STM32 MCUs Embedded software

Good evening everyone, I work with freeRTOS running on STM32F4. I receive data via UART and I want it to be with a binary semaphore, how to write the interrupt routine ?

Adding FreeRTOS without stack overflow check enabled leads to debug control loss.

As the title says, on a STM32F3DISCOVERY development board, if I create a fresh project with CubeMX,using OpenSTM32Workbench as an IDE, enable SWD support and FreeRTOS, but without the support for stack overflow detection in the FreeRTOS configuratio...

STM32L032CB: USB COM VCP; device is not identified on host computer. Clock and CDC Settings not correct?

Hi,I am using STM32L032CB MCU and a USB-C port and would like to achieve a virtual port com with CDC. I have generated the project with CubeMX where i enabled usb mode and configuration and assigned two pins DM and DP. Furthermore, i have enabled usb...

USB CDC to DAC

Hi, I am succesfully sending the data through libusb to the changed CDC example. But i need to use the CDC_Receive_FS function to send the data from USB buffer to DAC with DMA. So USB transfer speed is faster than the speed Timer triggers the DAC-DM...

How to check when Usart Tx is complete after DMA memory to Usart transfer?

STM32F334K6I am using LL_DMA memory to Usart function to transmit DMX data, and using the DMA_TransmitComplete interrupt to trigger the DMX break signal.This interrupt occurs before the last two bytes have been sent by the Usart, so the DMX frame is...
