Hello! Im receiving data by UART with DMA and now I wonder, how is HAL_UARTEx_RxEventCallback is ejecuted?Because I'm receiving and saving chunks of data in a buffer, then adding a header and a tail in this buffer to send it by USB, but I realized th...
Hello everyone,Is there a setting/command to limit the slew rate of I2C signals of a STM32F429ZI-Disco board? I know this feature is available on some Microchip micro-controllers.Thank you.
I know controllers push data to stack, PC to LR, etc. but how does this happens? Is it through software or hardware?If through software then where is the code which does this? and where does it come from? is it the compiler which adds it?If it is thr...

I cannot disable SPI global interrupt in SPI Settings--> NVIC sub settings when DMA is used for SPI. When DMA is activate, SPI global interrupt check box became deactive. I am not sure if it is a problem or not. I suspect from everything because I ha...
Hi everyone,I am working on a FD-CAN project and i am able to send a 64 byte data frame. But I want to send multiple frames of data with different IDs. Any help would be greatly appreciated!
Hello,I am working on a project with STM32H753 MCU and I want to reset the back up registers of the MCU every time I reset the MCU. With VBat presented on my board via external battery. The only way to do this is by writing to the specific register r...
I use Keil and V6 complier as project eaxmple in link, there is local var s in main() if set s=120 take more time USART2 Tx (PA2) can't send anything but set s=2,or comment this take time line it's work�?？ when not work condition PA2 always low ,...
hello everyone, I have question about SPI. I want to send 5 data repeatedly using hal_spı_transmit() function that means first data that will be send is pointer addres later the value will be send , first data is written to SPI->DR but secondly data ...
Hi everyone, I would like to use MAX3098E IC with STM32F303RE MCU. Should I connect the OUTZ index pin to the timer or just I/O ?Thanks
