Very very good for engineers like me who kind of are aware of basic stuff but don't know their way around IDE's and have last done embedded C during academic years. Many thanks an God Bless :)
One comment - I had to stop and start IAR Workbench after installation before I got the option to pick C under project types when creating a project. Before stopping and starting all I got was ARM for an option. When clicking on ARM I got nothing underneath it. What a wonderful set of lessons. Thank you for these. You really rock!

You are a fantastic teacher. Thanks for taking the time to do this series. Since I am using the Tiva C series Launchpad TM4C123GXL board I configured the microprocessor to TM4C123FH6PM in the IAR workbench - works perfectly with your tutorials.
The ARM Cortex-M uses the THUMB2 instruction set and does not use the ARM instruction set at all. Many THUMB2 instructions are 2-byte wide. However, some instructions, such as some branch instructions are 32-bit wide. All instructions must be aligned at 2-byte boundary (even address).

Awesome resource for beginners like me, thank you! I notice a difference in the assembly instructions generated in IAR and those generated in ARM uVision. Is there some way to configure the disassembly window to show the same instructions so I can step through the code with the video?
To my knowledge there is no way to make two different compilers produce the same exact code. Please note that this is NOT a matter of configuring the disassembly window in the debugger. The disassembly view merely shows the code stored in ROM and that code had been produced by the compiler. The compilers have a large degree of freedom in allocating the CPU registers to temporary variables, and many other things. In fact, this is how compilers compete with each other, by making claims like: "compiler ABC produces smaller or faster code than compiler XYZ". However, the most important aspects of the generated machine code will be the same for all compilers. For example, most functions will return with the BX LR instruction. --MMS

Hello Sir, Thanks for your this Embedded system series I enjoyed a lot with my applications and all its because of your help. But today i was again revising your lectures and in "Embedded Systems Programming Lesson 1: Counting" at 11:35 by mistaken you said:- a single hexa decimal represents a 4 "byte" (nibble) instead of "bits". Again thanks for your valuable help.
Nice tutorial. I've looked at a few of your tutorials quite some time ago, thinking I had to use the same development board. I got a little smarter, decided to use what I had...Atmel SAM4L-EK. I followed your tutorial with my board and it works. Way cool. Great job with the tutorials. On to the next lesson...
The question: "Can I use a board XYZ for this course" is by now the most frequently asked. The answer is NO. This course goes beyond generalities and frequently steps down to the low-level. This is the most effective way to learn truly embedded programming. To do this, you need specific software tools and a specific board. The boards and software tools used in this course are explained in lesson-0 ( ua-cam.com/video/hnj-7XwTYRI/v-deo.htmlsi=LXIj9_w36c6hSCVI ).
Thank you for the great videos, For me at (7:35) the highlighted instructions shows (0x40: 0x2000) instead of (0x40: 0x2001), why is there a difference?
I'm really glad that you liked the video. I'm not collecting any donations, but if you'd like to help, please spread the word about the course, so that others can benefit as well. For example, I think that a comment about this course on Embedded.com in one of their discussion forums could be very helpful. --MMS
Hello sir, I must be missing some setting because whenever I press DEBUG, it goes to startup code and all STEP buttons become inactive. By the way I am following this video using KEIL. The thing is it works whenever I am using your code . Do you have any video that shows the complete set up for KEIL uvision? Thanks for updating this series of lesson!
Great start to the course and looking forward to the rest. I do have one question about lesson 1. When I download and debug and step into, my program is counting (in hexadecimal) from R0 and not R1 like in your program. I have downloaded your program to my laptop and it counts from R1 (just like from your lesson) but for some reason my program counts from R0. Do you know why this might be or am I missing something. Thanks a lot.
The most likely difference between "your program" and "my program" is a different optimization level of the C compiler. The upcoming lessons of the course explain the embedded build process, but the compiler has a lot of freedom in allocating the CPU registers. In particular, the use of R0 instead of R1 is perfectly legal. Also, one more comment about counting: The program is not "counting in hexadecimal." The CPU is always counting in binary. Only the debugger shows the values in hex, but you can change it to show decimals. --MMS
hi i am in the second semester of BS computer science, know some data structures but nothing beyond that, what are the minimum prerequisites for someone who would like to test if they like embedded system programming, how far will this course make me go, if i have not accumulated much programming experience already
Thank you so much for taking the time to make these videos. I already have a TI-C3200 Launchpad. How can I use it with the IAR workbench? The debugger driver is missing
By now, the desire to use a different embedded board or a different development toolchain it is perhaps the most frequently asked question. Unfortunately, it won't allow you to follow along and use the specific project files that accompany this course (at state-machine.com/quickstart ). To really benefit from this video course, you need the exact same hardware and software. The TivaC LauchPad has been selected specifically for its low cost ($12.99). Also, the course uses only free development toolchains (initially IAR EWARM KickStart, later TI CCS free edition, and later ARM-KEIL MDK evaluation version). --MMS
This is perhaps the most frequently asked question. The short answer is NO. To follow along this video course you need the exact board that is being used (TavaC LaunchPad). This is because the *peripherals* of this board are different than STM32, even though the CPU is the same Cortex-M4. I hope this makes sense. --MMS
Haha - I am also many years in Programming, but I have only 10 fingers. :-( But Programming for a long time modifies the body. I have 4 eyes: One to look at the actual line of code, one for the CPU Registers, one for the Disassembly and the last one on the keyboard, because I never have been able to type without looking on the keyboard. ;-)
Are cortex m0+ and cortex m4f too different from each other? I'm planning to follow your videos, which I'm very thankful that you uploaded them in youtube, but my mcu is cortex m0+.
Hello, I think the structure of this free is excellent. Thank you for the course. I just have 1 question. I am using keil microU, since it is free. I see the course is done with iar, but also keil is supported/mentioned. I can understand and follow along with most of the video. I was wondering if you had videos/resources dealing with keil microU? I have everything setup, drivers, devices detected no problems there. Staring at lesson 1 main.c, counter example right now. It's just that there are some differences and I'd like to make sure I can follow along to best of my ability, given the differences between iar and keil, I'd like to avoid selecting an option that sounds like it is correct but for keil it is actually another option. For example I can open the pre-made lesson 1, but in making a new project I am unsure about some things and so I haven't done it. I will keep trying and maybe I figure it out. I am new to much of this but am eager to learn. Thanks again for the playlist.
Hi FM1908Y! The KEIL-MDK toolset with the uVision IDE is introduced in lesson #21 ua-cam.com/video/AoLLKbvEY8Q/v-deo.htmlsi=U-K3HAi46PSLujWc&t=94 . Please watch. --MMS
@@StateMachineCOM Thank you for your response. I have just 1 other quick question. I noticed next to debug option, f7, there is a flash option. I know the tivac board comes with a pre-installed program that displays light which the user can change by pressing the button near it. I was given several tivac boards by friends for this course. I clicked on flash, and now the default light program won't appear. Is there a way to factory reset or something like that? I'm not sure if I've done something that could cause trouble for me later. Curious to know if there is something I could do. Thanks again for your response and this course.
@@FM1908Y You should know that every program that you upload to the board (TivaC, STM32 NUCLEO, and most others) overwrites the previous program and stays in the board *permanently* . This is because the program is placed in the Flash memory inside the microcontroller, which works similarly as a USB drive. So, even if you power down the board, your most recent program starts right up when you turn it on again. If you wish to go back to the original factory demo program, you need to get that program (could be just the binary) from somewhere and you need to upload that to the board. Now, is it potentially dangerous? You bet it is! If you program some garbage, you might lock up your board. In fact, TivaC can be locked up quite easily. If this happens to you, please go to the companion web-page to this video course ( www.state-machine.com/video-course ) and look for the document "Troubleshooting TivaC LaunchPad". You'll find there how to unlock a "bricked" TivaC board. --MMS
@@StateMachineCOM Thank you very much again for your response. As you can see I am still very much new to this. Sometimes my excitement gets the better of me. Thank you for your time and comments. I do programming as a hobby (C mostly), but I'd like to learn more about embedded C/microcontrollers to take care of basic functionality at my place of business. I own a restaurant so I've written things in C to take care of basic managerial tasks, so embedded C seems like something fun to implement for basic tasks, like lights or sensors for various things. Thanks again!
Great lectures. I'm looking forward to complete it. In college we are using TI MSP430g2553 launchpad I'm wandering is it compatible with the lectures. Thanks again for the lectures especially introducing the IAR workbench simulator. In earlier course we used Edsim for 8051 which helped a lot to understand how the instructions work.
This course focuses on ARM Cortex-M, so most lessons use that specific CPU. However, lesson 11 and lesson 17 also used the MSP430g2553 LaunchPad to demonstrate differences between Cortex-M and a simpler CPU.
In principle, you should be able to use any IDE for the presented code, and VS Code is one of those "sexy" ones currently gaining popularity. However, such a change involves a different compiler for ARM, different startup code, and different linker script (later lessons in this course explain all these things). So to make it practical, support for VSCode would require creating a ready-to-use projects for this IDE. Adding such projects is possible in the new, updated, and extensible project structure introduced in the updated lesson-0 ( ua-cam.com/video/hnj-7XwTYRI/v-deo.htmlsi=RX8ElGhH_slY1UgV ). Adding such projects to all 40 lessons at this point would be a huge undertaking, but perhaps some of the projects could be added depending on popular demand. --MMS
Another question. Minute 8:58. Line underlined in green. 0x42:0x1c49. 0x42 is the addres of the memory but i don't understand what is this 0x1c49. Thanks
8:18 Aren't ARM instructions 32 bits (so 4 bytes)? Since each memory address holds one byte, shouldn't the addresses be incrementing by 4 each time? Eg 0x40, then 0x44, then 0x48, etc.
The ARM Cortex-M CPU does NOT execute the classic "ARM" instructions. Instead, this CPU executes the THUMB2 instruction set, where most instructions are 16- bit, but some are 32-bit. This means that all instructions are aligned at even addresses, but not necessarily divisible by 4.
@@StateMachineCOM Thank you for your quick response! I'm so glad to see that you actively respond to your viewer's questions! I have been frustrated many a times by content creators who just post tutorial videos but don't participate in comment discussions.
Sorry if this has been covered somewhere already but can I follow this course on mac or linux? I have the hardware already. If not it's no worries, I will still benefit from studying these videos
Yes, the question about using Linux or macOS host computers has been asked a lot. Here is my standard answer: You might try to install VSCode and then some extensions for embedded programming (e.g., please google for "Keil Studio extensions"). I've not tried it yet, so I can't comment on how it works in practice. The approach of this course is to provide the simplest and easiest path for getting started. And this means using the Windows environment because, for better or worse, historically the embedded community chose Windows as the primary development platform. That's why most embedded tools work on Windows first, and then maybe on other platforms. Today, you have other options, but if you are truly serious about embedded development, I would still recommend getting yourself a Windows machine. --MMS
@@StateMachineCOM Thanks, I assumed Linux would be the standard OS. I'm going to try and follow along with Keil Studio for VS Code on my Linux machine. Cheers again for this fantastic resource.
@@takyon24 Some embedded projects have indeed moved to Linux. For example, the Zephyr RTOS clearly prefers Linux (but again, what would you expect from a Linux foundation project?) Also, Linux is preferred for CI/CD work because it better supports containers like Docker. However, most of these things are also available on Windows (with WSL). Actually, Windows is making a come back. After all, the most popular and "sexy" VSCode is developed by... Microsoft. --MMS
Yes, you can use Keil/ARM MDK with the TivaC LauchPad board. But you will need to create the Keil projects yourself, because the projects available from the companion web-page at state-machine.com/quickstart are for IAR EWARM. This course switches to Keil/ARM MDK at lesson 21. This lesson 21 explains also how to download and install the free (size limited) version of Keil MDK. --MMS
Hi i am trying to follow your tutorials, love the way you explain. I am having one problem that my c dialect in compiler options shows only c89 and c11. how can i have similar dialect? is it ok to use the same dialect?
The newer IAR EWARM (v8.11) seems no longer to support the C99 standard. Instead, they still support the C89 and C11. For this course, please select the newer C11 (ISO/IEC 9899:2011) language standard. --MMS
Hi my launch pad came with the LXM4F120H5Q instead of the LM4F120H5Q, when I tryed to enter into debug mode I get a fatal error pup up, How can I fix this?
i like your videos...i am more interested and i need some information...is this possible in IAR that we can watch the GPIO port in Analyzer or something like that...or if we design a graphic interface for the ports....if this is possible then how i can do that...
It doesn't work that way. To follow along this course and directly use the projects from the accompanying web-page (www.state-machine.com/quickstart/ ), you would need to use the exact same development board (TivaC LaunchPad). Having said that, the general concepts you will learn will apply to Infineon, ST, NXP, Renesas, Silicon Labs, and many other ARM Cortex-M-based MCUs. --MMS
Really like the video series so far. But ran into a snag. My counter does not increment at all. I even tried directly assign it values on each line and it still does not change. Am I in the wrong view or something?
Thanks this is a great tutorial. My question is I have OmapL138 development board and would like to use it with these examples could you please help me the settings. thanks
+Bashir Abdi The OmapL138 is a dual-core SoC with ARM926EJ-S and C674x DSP. The ARM9 core is the "classic" ARM, which is *different* than the ARM Cortex-M used in this course. (Of course there are some similarities, but ARM9 and Cortex-M have different instruction sets--ARM/THUMB vs THUMB-2, respectively). For these reasons this course is not applicable to your OmapL138.

I followed your tutorial with my board and it works. Way cool. Great job with the tutorials. On to the next lesson...
Great lessons, You are a very good teacher
Great tutorial. Question...the memory view location does not have the same data as in the Disassembly view
Brilliant! Many thanks!
Hi, I want to know that can i use raspberry pi 3 model b for this course? Thanks For Sharing the Knowledge.
The question: "Can I use a board XYZ for this course" is by now the most frequently asked. The answer is NO. This course goes beyond generalities and frequently steps down to the low-level. This is the most effective way to learn truly embedded programming. To do this, you need specific software tools and a specific board. The boards and software tools used in this course are explained in lesson-0 ( ua-cam.com/video/hnj-7XwTYRI/v-deo.htmlsi=LXIj9_w36c6hSCVI ).
Nice tutorial. The flow and style is great.. Did you write the narration script ahead of time?
Thanks..
Yes, absolutely. I prepare a script and carefully optimize it for maximum content with minimal waste of time.
Great video, Miro! Are the instructions 2-bytes wide because of the Thumb encoding?
You are awesome ..😎💯
Awesome tutorial. Which graphics editor did you use for your presentation?
The tutorial was recorded and edited in Screencast-O-matic professional edition.
Thank you very much.
Very nice tutorial! thank you
Thank you for the great videos, For me at (7:35) the highlighted instructions shows (0x40: 0x2000) instead of (0x40: 0x2001), why is there a difference?
sorry your computer showed (0x40: 0x2100)
Thanks a lot for the great work !
Where do I go to donate? This has been extremely helpful so I would like top give back to those that made my job so much easier.
I'm really glad that you liked the video. I'm not collecting any donations, but if you'd like to help, please spread the word about the course, so that others can benefit as well. For example, I think that a comment about this course on Embedded.com in one of their discussion forums could be very helpful.

Hello sir, I must be missing some setting because whenever I press DEBUG, it goes to startup code and all STEP buttons become inactive. By the way I am following this video using KEIL. The thing is it works whenever I am using your code . Do you have any video that shows the complete set up for KEIL uvision?
Thanks for updating this series of lesson!
how a great course, thank you so much for your effort. God bless you, he is coming soon, be ready.
Great start to the course and looking forward to the rest. I do have one question about lesson 1. When I download and debug and step into, my program is counting (in hexadecimal) from R0 and not R1 like in your program. I have downloaded your program to my laptop and it counts from R1 (just like from your lesson) but for some reason my program counts from R0. Do you know why this might be or am I missing something. Thanks a lot.
The most likely difference between "your program" and "my program" is a different optimization level of the C compiler. The upcoming lessons of the course explain the embedded build process, but the compiler has a lot of freedom in allocating the CPU registers. In particular, the use of R0 instead of R1 is perfectly legal. Also, one more comment about counting: The program is not "counting in hexadecimal." The CPU is always counting in binary. Only the debugger shows the values in hex, but you can change it to show decimals. --MMS
Some programmers have 16 fingers, but some have 2 fingers, there are also programmers who have 8 fingers, but they are rare.
hi i am in the second semester of BS computer science, know some data structures but nothing beyond that, what are the minimum prerequisites for someone who would like to test if they like embedded system programming, how far will this course make me go, if i have not accumulated much programming experience already
11:17 omg those 16 fingers, programmers' :P
laughing so hard LOL
LOL
you are god, thanks for this! I will have to figure out how to transfer my programs from linux
Hi, Thank you for this video, I am having problems with create new project.there are no project templates. all it has is "Empty Projects"
Thank you so much for taking the time to make these videos. I already have a TI-C3200 Launchpad. How can I use it with the IAR workbench? The debugger driver is missing
By now, the desire to use a different embedded board or a different development toolchain it is perhaps the most frequently asked question. Unfortunately, it won't allow you to follow along and use the specific project files that accompany this course (at state-machine.com/quickstart ). To really benefit from this video course, you need the exact same hardware and software. The TivaC LauchPad has been selected specifically for its low cost ($12.99). Also, the course uses only free development toolchains (initially IAR EWARM KickStart, later TI CCS free edition, and later ARM-KEIL MDK evaluation version). --MMS
Thank you so much for the effort 😀
Hello Julio, do your laptop see the device?
Great Work! can I use the cortex M4 from STelectronics for this tutorial?
This is perhaps the most frequently asked question. The short answer is NO. To follow along this video course you need the exact board that is being used (TavaC LaunchPad). This is because the *peripherals* of this board are different than STM32, even though the CPU is the same Cortex-M4. I hope this makes sense. --MMS
at 11:36 you say 4 bytes is a nibble. that is incorrect. a nibble represents 4 bits
very good tut!!! thank you
OK, in the upcoming lessons I will explain how to generate the map file and I will show how to read it.
--Miro
Haha - I am also many years in Programming, but I have only 10 fingers. :-(
But Programming for a long time modifies the body. I have 4 eyes: One to look at the actual line of code, one for the CPU Registers, one for the Disassembly and the last one on the keyboard, because I never have been able to type without looking on the keyboard. ;-)
can we also use Raspberry pi for learning this programming
Are cortex m0+ and cortex m4f too different from each other? I'm planning to follow your videos, which I'm very thankful that you uploaded them in youtube, but my mcu is cortex m0+.
Hello, I think the structure of this free is excellent. Thank you for the course. I just have 1 question. I am using keil microU, since it is free.
I see the course is done with iar, but also keil is supported/mentioned. I can understand and follow along with most of the video. I was wondering if you had videos/resources dealing with keil microU?
I have everything setup, drivers, devices detected no problems there. Staring at lesson 1 main.c, counter example right now.
It's just that there are some differences and I'd like to make sure I can follow along to best of my ability, given the differences between iar and keil, I'd like to avoid selecting an option that sounds like it is correct but for keil it is actually another option. For example I can open the pre-made lesson 1, but in making a new project I am unsure about some things and so I haven't done it. I will keep trying and maybe I figure it out.
I am new to much of this but am eager to learn. Thanks again for the playlist.
Hi FM1908Y! The KEIL-MDK toolset with the uVision IDE is introduced in lesson #21 ua-cam.com/video/AoLLKbvEY8Q/v-deo.htmlsi=U-K3HAi46PSLujWc&t=94 . Please watch. --MMS
@@StateMachineCOM Thank you for your response. I have just 1 other quick question. I noticed next to debug option, f7, there is a flash option.
I know the tivac board comes with a pre-installed program that displays light which the user can change by pressing the button near it. I was given several tivac boards by friends for this course.
I clicked on flash, and now the default light program won't appear. Is there a way to factory reset or something like that?
I'm not sure if I've done something that could cause trouble for me later. Curious to know if there is something I could do. Thanks again for your response and this course.
@@FM1908Y You should know that every program that you upload to the board (TivaC, STM32 NUCLEO, and most others) overwrites the previous program and stays in the board *permanently* . This is because the program is placed in the Flash memory inside the microcontroller, which works similarly as a USB drive. So, even if you power down the board, your most recent program starts right up when you turn it on again. If you wish to go back to the original factory demo program, you need to get that program (could be just the binary) from somewhere and you need to upload that to the board.
Now, is it potentially dangerous? You bet it is! If you program some garbage, you might lock up your board. In fact, TivaC can be locked up quite easily. If this happens to you, please go to the companion web-page to this video course ( www.state-machine.com/video-course ) and look for the document "Troubleshooting TivaC LaunchPad". You'll find there how to unlock a "bricked" TivaC board. --MMS
@@StateMachineCOM Thank you very much again for your response. As you can see I am still very much new to this. Sometimes my excitement gets the better of me. Thank you for your time and comments.
I do programming as a hobby (C mostly), but I'd like to learn more about embedded C/microcontrollers to take care of basic functionality at my place of business. I own a restaurant so I've written things in C to take care of basic managerial tasks, so embedded C seems like something fun to implement for basic tasks, like lights or sensors for various things. Thanks again!
Thank You Sir
Great lectures. I'm looking forward to complete it. In college we are using TI MSP430g2553 launchpad I'm wandering is it compatible with the lectures. Thanks again for the lectures especially introducing the IAR workbench simulator. In earlier course we used Edsim for 8051 which helped a lot to understand how the instructions work.
This course focuses on ARM Cortex-M, so most lessons use that specific CPU. However, lesson 11 and lesson 17 also used the MSP430g2553 LaunchPad to demonstrate differences between Cortex-M and a simpler CPU.
Are we able to use Visual Studio Code IDE to follow along?
In principle, you should be able to use any IDE for the presented code, and VS Code is one of those "sexy" ones currently gaining popularity. However, such a change involves a different compiler for ARM, different startup code, and different linker script (later lessons in this course explain all these things). So to make it practical, support for VSCode would require creating a ready-to-use projects for this IDE. Adding such projects is possible in the new, updated, and extensible project structure introduced in the updated lesson-0 ( ua-cam.com/video/hnj-7XwTYRI/v-deo.htmlsi=RX8ElGhH_slY1UgV ). Adding such projects to all 40 lessons at this point would be a huge undertaking, but perhaps some of the projects could be added depending on popular demand. --MMS
Hi , The registers you are viewing, minute 7:08, are of the board that you have selected and you will have definitely connected to your PC? Thanks
Another question. Minute 8:58. Line underlined in green. 0x42:0x1c49. 0x42 is the addres of the memory but i don't understand what is this 0x1c49. Thanks
@@lorenrus The 0x1C49 is the machine instruction which means "ADDS R1, R1, #1"
8:18
Aren't ARM instructions 32 bits (so 4 bytes)? Since each memory address holds one byte, shouldn't the addresses be incrementing by 4 each time? Eg 0x40, then 0x44, then 0x48, etc.
The ARM Cortex-M CPU does NOT execute the classic "ARM" instructions. Instead, this CPU executes the THUMB2 instruction set, where most instructions are 16- bit, but some are 32-bit. This means that all instructions are aligned at even addresses, but not necessarily divisible by 4.
@@StateMachineCOM Thank you for your quick response! I'm so glad to see that you actively respond to your viewer's questions! I have been frustrated many a times by content creators who just post tutorial videos but don't participate in comment discussions.
Sorry if this has been covered somewhere already but can I follow this course on mac or linux? I have the hardware already. If not it's no worries, I will still benefit from studying these videos
Yes, the question about using Linux or macOS host computers has been asked a lot. Here is my standard answer: You might try to install VSCode and then some extensions for embedded programming (e.g., please google for "Keil Studio extensions"). I've not tried it yet, so I can't comment on how it works in practice. The approach of this course is to provide the simplest and easiest path for getting started. And this means using the Windows environment because, for better or worse, historically the embedded community chose Windows as the primary development platform. That's why most embedded tools work on Windows first, and then maybe on other platforms. Today, you have other options, but if you are truly serious about embedded development, I would still recommend getting yourself a Windows machine. --MMS
@@StateMachineCOM Thanks, I assumed Linux would be the standard OS. I'm going to try and follow along with Keil Studio for VS Code on my Linux machine. Cheers again for this fantastic resource.
@@takyon24 Some embedded projects have indeed moved to Linux. For example, the Zephyr RTOS clearly prefers Linux (but again, what would you expect from a Linux foundation project?) Also, Linux is preferred for CI/CD work because it better supports containers like Docker. However, most of these things are also available on Windows (with WSL). Actually, Windows is making a come back. After all, the most popular and "sexy" VSCode is developed by... Microsoft. --MMS
can i use Tiva™ C Series LaunchPad instead??
Hi... there are any version for linux mint (IAR emmbedded workbench)
can i use keil instead of iar
pls reply i need urgently
Yes, you can use Keil/ARM MDK with the TivaC LauchPad board. But you will need to create the Keil projects yourself, because the projects available from the companion web-page at state-machine.com/quickstart are for IAR EWARM. This course switches to Keil/ARM MDK at lesson 21. This lesson 21 explains also how to download and install the free (size limited) version of Keil MDK. --MMS
wat is the difference between this emedded system programming and embedded c programming?
Hi i am trying to follow your tutorials, love the way you explain. I am having one problem that my c dialect in compiler options shows only c89 and c11. how can i have similar dialect? is it ok to use the same dialect?
The newer IAR EWARM (v8.11) seems no longer to support the C99 standard. Instead, they still support the C89 and C11. For this course, please select the newer C11 (ISO/IEC 9899:2011) language standard.
--MMS
Is it possible to use code compiler studio without connecting launchpad to the computer? I mean CCS as simulator.
Hi my launch pad came with the LXM4F120H5Q instead of the LM4F120H5Q, when I tryed to enter into debug mode I get a fatal error pup up, How can I fix this?
what is benefit of ARM over PIC
i like your videos...i am more interested and i need some information...is this possible in IAR that we can watch the GPIO port in Analyzer or something like that...or if we design a graphic interface for the ports....if this is possible then how i can do that...
Can i develop the Infineon 275 boards with this tool
It doesn't work that way. To follow along this course and directly use the projects from the accompanying web-page (www.state-machine.com/quickstart/ ), you would need to use the exact same development board (TivaC LaunchPad). Having said that, the general concepts you will learn will apply to Infineon, ST, NXP, Renesas, Silicon Labs, and many other ARM Cortex-M-based MCUs. --MMS
Thank you so much.
Really like the video series so far. But ran into a snag. My counter does not increment at all. I even tried directly assign it values on each line and it still does not change. Am I in the wrong view or something?
Nevermind, it just started working. Further digging says that the variable maybe was no longer available to optimize stuff. Weird.
Thanks this is a great tutorial. My question is I have OmapL138 development board and would like to use it with these examples could you please help me the settings. thanks
+Bashir Abdi The OmapL138 is a dual-core SoC with ARM926EJ-S and C674x DSP. The ARM9 core is the "classic" ARM, which is *different* than the ARM Cortex-M used in this course. (Of course there are some similarities, but ARM9 and Cortex-M have different instruction sets--ARM/THUMB vs THUMB-2, respectively). For these reasons this course is not applicable to your OmapL138.
