Hello,I am trying to use the HAL_UARTEx_ReceiveToIdle_DMA function() but the IDLE function don't work.I call the function here : /* Extern variables */ extern UART_HandleTypeDef huart4; extern osEventFlagsId_t comEventHandle; extern osMessageQueueId...

Hello everyone, I'm working on a motor control project using an STM32 microcontroller (TIM1 and TIM8 timers), and I need to implement a soft Break to safely stop the PWM signals with proper transitions (respecting Dead Time and setting the outputs to...

Thank you Karl,The DMA doesn't work since the new STM32G473. I have tried with your example but it is not working with the G473 and the NULL byte. I have gave up, and change to normal UART IT. Thank you for your help.

Here some frames KO (modbus) : Here some frames OK (UART ASCII) :

I have tried something, if I use Realterm and I send some ASCII byte, it works like a charm. BUT If I use KScada Modbus Doctor V2.10 the IDLE doesn't work. I am wondering if the frame is ok on modbus doctor. But my other question is, if I have a prob...

Here the code attached. it is a .C file and the IOC project.

After your reply I have checked something, and I thing I have something interesting.When I use Putty and I send only 1 bytes the IDLE work every time.If I send 2 bytes, the IDLE is never called and its never re-works.I have to reboot the micro to re-...
