good tutorial thanks a lot keep it up

Another super usefull video! Little addition, I had to set the output speed to very high for a 50mhz clock. See OSPEEDR register.

Thanks a lot this is great stuff! I was using SPI DMA transfer with HAL to send data to a DAC, but realized it took 1.5us for the transfers to start, limiting a lot the maximum update frequency of the system, considering sending 16bits at 50mhz only takes about 500ns. So using simply the DR register together with your interrupt explanation (to send the 2nd channel data after the first one is done) is a much better solution.

Thanks. It worked for me. For anyone playing with a development board NUCLEO-H745ZI-Q ( MCU : STM32H745ZIT6), replace USART_ISR_TXE by USART_ISR_TXE_TXFNF. It will work well.

For calculating the baud rate... why the input frequency is 4MHz when USART1 is connected to ABP2 which frequency is 80MHz?

Great video! Very informative! Looking forward to more register level programming tutorials!

Is this what is meant by bare-metal programming of GPIO?

please take more video about STM32 Bare metal

it works! thanks

I don't have the pack installer enabled for my keil uvision (non commercial) what should I do ?

Your typing is a bit too fast for me to follow, but, that's why they pay you the big bucks. It's a good thing that this controller is not too complex! Actually, it's a good example of the "double-edged sword" oh having incredible flexibility in a small device, but requiring quite a bit of internal configuration to get through the flexible pathways... I started with XC6801, 1978, which was a kind of beginning of the trend, with 2 or 3 functions on port pins, and a few registers to get the desired results.

Thanks for showing monitor screen big enough to see on my tablet, since I'm stuck in a hospital bed...

Your videos on this subject are absolute GOLD, thanks so much!

Such a useful video and such a nice presentation!! Thankyou so much... hats off to the efforts taken for making this video

make more videos

The Mic quality though! ASMring into my ear

Absolutely fantastic! I've scoured countless resources in search of a comprehensive guide on configuring and initializing hardware from scratch, steering clear of manufacturer libraries. Your content is a gem-thank you for simplifying what seemed like a daunting task!

Curious, when you start a project. Do you install any of the GPIO packs or do you only install the Device startup and CMSIS core packs?

My spi driver search is finally successfull now, Thankyou so much Z- The-Programmer

hello so, where i can get myUART.h file?)))

This is excellent! Most others are using cubeide which is fine but more stuff to learn. I like to just look at the datasheets although these are a bit gnarly.

Such an insightful video, i hope u keep making more videos about writing device drivers for Microcontrollers like STM32 for different peripherals such as UART DMA I2C I2S ADC, i really hope that man, keep up the good work 👌

Well done! All of this effort for a simple UART interface! Well achieved and thank you for your excellent presentation. (Love the graphics)

very clear and straight to the point. Thank you!!

Thanks.

At 3:08 you say you start enabling the timer by setting bit one of the clock enable register. (1u << 0) sets bit zero not bit one. Isnt it?

my guy you're a life saver xoxo <3

hello, a very good job ,please continue making videos, do you have any community to join ?like discord or something

Very very good sir Plz make more videos ,on UART,SPI ,I2C, CANN ,EXTRA by St link, and stlink v2

Very good sir

This is great could you please make a video using interrupts for timer output compare and input compare?

i am not able to read more than 256 bytes in externnal spi

bro where you install that dark theme for keil

Hello, this is a great example. Can you please correct the github link. It shows 404 error.

Noice

great start

Getting better

Love your voice!

Interesting!

Very Informative!

Great vid! Very Informative. Please more

Good explanation! Thanks you

Great video! One recommendation is that it is best practice to use the CMSIS library and all the defines that come with it. It is almost impossible for someone to tell what (0x1 << 1) means(unless you want to dig through the reference manual) when you could use RCC_AHB1ENR_GPIOBEN. This is still bare-metal programming and it greatly increases the readability of your code. Great work!

Really nice video

Great, good work!

Love the Tutorial man, very simple, clearly explained and easy to follow, I have a suggestion and a request. the suggestion being, you should include a link to the downloadable source code for whose who are following your tutorials at a pace, and secondly can you please do a video on STM32 serial communications?.....keep up the great videos.....
