Why is it necessary to use the I2C debugger to get the simulation to work? Shouldn't the DS1307 return the clock information when it is selected and initialized? If we built this actual circuit you would not have an I2C debugger but the clock would function, correct? I am trying to understand what the need for the I2C debugger is in the proteus simulator... Thank you
+Hưng Nguyễn Quốc Hi. The procedure will be more or less the same only some small changes to the code. The major thing to note is PIC18F26K20 operates with 3.3V while PIC16F887 operates with 5V
I noticed that the display of the seconds is quite erratic. Sometimes it jumps a couple of seconds at a time and is delayed at other times. At first i thought it was something to do with your editing but when I simulated it myself I had the same problem. Is this a simulation problem or will it be the same when in hardware?
Hi. It might be a simulation problem as it reads current time form your computer, and this can be affected by your computer CPU available resources as simulation is quite a memory intensive task. In hardware you may not experience the same problem.
what happens if the read data is longer than 8 bit? The example you did the highest return value was 99 (0x63) so what happen if the return data is 65535? Would i have to do i2c read twice to get the first 8 bit(MSB?) then the next 8 bit(LSB)? how would I combine this data to be usable information?
To read more than once or to access multiple registers, you can call a read function multiple times as explained in this video: ua-cam.com/video/E_bAO7MwadQ/v-deo.html
+Enrrique Flores hi ! I guess you mean DS3231. There is no much differences between this chip and the DS1307 except for accuracy. The DS3231 is more accurate. It's not much affected by outside temperature. The code of the DS1307 should work well with DS3231 as they have the same time registers and can be accessed the same way. Read the datasheet and compare.
+Enrrique Flores go ahead and use the i2c functions as described in the tutorial. Buf remember there are registers and instructions which are not available when using a PIC16F device such as LAT register, etc.
+Siti Nazirah Hj Damit Slow compared to what? Remember this is simulation it's not always gonna run like in hardware. Maybe it's your simulation that's slow. There is a simulation clock at the bottom bar of proteus runing immediately once you press the run button. Check if your minutes are in synchronous with that clock.
I used 18f26k20 in both my Proteus and mikroc pro. It display ds1307 clock and sare at one corner on Proteus but is the LCD that is no displace. At the stimulation log, error U1 (Pic18 )PC =0x0300.
Hi, one more great video thanks, i want to write code to count minutes when i press button, for example when i press button if it is 14:50 and press one more time 14:55 it should count and display every minute like 1, 2,3,4,5 or simply make another counter, how can i do that thanks a lot
Student Companion SA i am trying to make counting system , like money, lets say every 1 minute is 2$ , so i have this real time digital clock and when i press it should start counting and should be displayed like a counter, for example when 1 m passes 2$ , 2 passes 4$ should be displayed, thanks
+Islombek Mamatov then you probably won't need a real time chip. You can use a pic internal timer or even interrupt to achieve this. When a button is pressed it can generate an interrupt then you can start counting.
Student Companion SA i got it , thank you I also found when i run this tutorial simulation in proteus seconds are changing very slowly like 1 second in display changing in 3 seconds, can you explain that?
Usually because this is simulation, it will not run as real as in hardware, it will depend on some simulation limitation, the speed of your computer among others. But if the simulation is very slow, check the oscillator frequency you selected is not too low compared to the oscillator frequency you used in your project.
Hi! I have a micro sd card module and a ds3231 RTC module. One of this module work with SPI, other is work with I2C. My question is can i use this modules in one MSSP on pic? (I have a pic 18f4685). I found "I2C bit banging" for my problem, but didn't understand anything how can i do it.
The I2C and SPI use the same module in the PIC, so you can either use only the SPI or I2C if the PIC habe only one MSSP module, the only option to use both is to use the bit banging for one interface. But if you choose a PIC with 2 MSSP modules, you can use both SPI and I2C hardware modules. Why did you choose this PIC and you are not even using CAN bus? If you choose a PIC with 2 MSSP modules, you can make your life easy.
My project code is 75k of flash. So i need to choose min. 96k flash size MCU. I live in Turkey and you can't find the all MCUs in Turkey. And also i don't have a smd soldering station. At the first i didn't know am i need SPI ind I2C modules at the same MCU. So i choosed the pic18f4685 DIP version. I don't need a CAN bus communication. I will use 2 SPI, 1 I2C module and uart communication. Therefore i will change the MCU to has 2 MSSP and 128k flash size MCU. (If ı find MCU has a usb interface, it'll be nice.) If i didn't find DIP model in Turkey, maybe i will buy from abroad. Thank you for answering my question!
Yes, there are many MCUs in DIP packages that have 128KB of memory that you can use and have more than 1 MSSP. That can make your code easier to write than by using bitbanging. Also try to select a newer PIC model, there are cheaper, more powerful and with more features than old ones like the one you selected. There is no good reason to start a new project using an old PIC if newer alternative is available.
You can use this tool to set your PIC requirements and it will give you a list that meet your requirements: www.microchip.com/maps/Microcontroller.aspx If shipping cost is not a lot, you can always buy directly from Microchip, they are quite cheaper. But try to buy first locally in Turkey if possible.
@@StudentCompanion Do you have any suggestions? I was using the pic16f series 6 years ago, I switched from flash failure to the 18f series. I don't know the new MCUs very well.
Yup, this tutorial is excellent. Has anyone figured out an idiot proof way of loading config bits using MIKROC pro and pickit3 ? i've purchased the MikroProg but I haven't played with it yet. Cheers, Lucius
Hi. Do you mean MPLAB Code Configurator? If that's what you mean, this is mikroC tutorial it does not use it. It has its own library functions. It's a different compile than XC8.
Firstly, thanks for your fast reply. I tried to make PIC's ADC reads voltage divider from keys. And when you press a key, it will give you a voltage value. The PIC compares with a range and "know" what key was pressed. Have you ever try it ?

j'ai pas compris bien
@@salmam5118 que ce que tu n'a pas compris? la conversion? tu ne sais pas c'est quoi le bcd? Tu ne sais pas pourquoi nous avons fais la conversion? Il faut bien decrire ta question pour que nous savions ton problem.
Please guys who can help me with something ? I want to turn on a LED after 22:00h but I cant figure out how to do this condition !!! who can help me !!
+walid_ Thegift hi. Will the LED remain ON after that?
the condition is about turning on the LED between 7:00h and 22:00h and its still off after 22:00h to 7:00h that's what I need to do in my program, but the problem is that I didn't understand how to do this condition with this program and how can I get the hour to write it in the if condition !!!! if(!!!!!!!){PORTD.RD0=1;}else{PORTD.RD0=0;}
Thank's
Please send me source code hex file & design file

please provide me codes and proteus simulation anyone
led text moving message with keyboard usb project still waiting plus code
Hi Daniel Simiyu, We are busy with your project, which PIC are you going to use? You want it to use USB but pic16f88/16f877a don't have USB interface. you can only use UART with these PIC
thanks for your efforts and making projects real ,can we use 16f877a for UART and 18f450 for usb. Now now now oh USB VS UART, very difficult again/ my wishes are to use keyboard as my text message input and have minimum components
+Daniel Simiyu You Can use USART and send data from your windows terminal.
