Hi ST_community."Programing STM32F429ZIT6 micro"I have a question: what are the options to burn/download a program into a STM32F429?At this moment, I am working on STM32F429ZIT6-DISC1 board, now, everything is ok, everything is done it throughout ST_...

Hello STM32 Community.I need your support, I am trying to do a small project where I need to use for example a var where PWM frequency is saved, as I need to calculate the period I just write a division 1/test_float and the result must be the period....

Hi all.I am trying to connect 2 STM32F103C8 (blue pill board).I run a test using just ONE STM32 using SPI1 as Master and SPI2 as Slave, all configurations were working fine (FullDuplex, Master Transmite. receive only Slave....every test was fine (all...

Hello everyone.I am working on a project, where It has 6 PWM channels, and there will be 3 channels active at time, As all PWM channels must have the same frecuency, all PWMs channel must start and stop at the same time, I am trying to define TIM2 as...

Hi ST Community.I need your help. I am working on a PWM Proyect, Duty cicle must be change every period, and there is delta time where the PWM must be OFF.I am using a Timer, it fire an interrution and this interruption set a flag to 1 in order to r...

Hi gregstm.When I said PIN 138 connected to GND, I was thinking in a final project board, no in an experimental board, but I was thinking to use a header to be used when I needed to burn the program or change it any time I need if it necessary..... b...

Hi Tesla DeLorean.Thanks a lot for your quickly answer.I was checking the APP Note AN2606, so using USART1 (for example) we can flash/debug the MCU, boot0 (PIN 138) must be connected to GND, so, Main Flash memory is selected as boot space.So, the ST-...

TDK, thanks a lot for yopur comments.I was making some mistakes, In order to see/check if SPI was working between STM32F103 was using debuger:if i use just one break point....in HAL_SPI_ErrorCallback, the comunitacion work fine, as there is not any e...

How to burn (download) a program into a Micro if I am not using a Experimental board as Discovery board....

STM32F103, Why some division are equal to zero when the result must be a float value, but not zero.

Two STM32F103C8´s connected by SPI. Master is sending data=3 as test, Slave STM received the data, HAL_SPI_RxCpltCallback is fire, but HAL_SPI_ErrorCallback is fire too, HAL_SPI_GetError=4 (overload)

TIM2 as Master and TIM3 as Slave is not working on Blue Pill board (STM32F103C8)

STM32F103C8, How to stop PWM signal?
