Resolved! Can the STM32G4’s DMA multiplexer (DMAMUX) be synchronized to a timer other than LPTIM?

I’m working with an STM32G474RE chip, and I’m trying to use the synchronization feature of the DMA multiplexer to time when a DMA transfer to SPITX should occur. I’d like to have this timed synchronously to some other timer events.Looking at the docu...

Resolved! GPIO for SPI communication ST example is not set?

Dear ST Hello,I am using the ST example for SPI communication for getting started with STM32F429i-discovery.This the header of the main file. ******************************************************************************   * @file SPI/SPI_FullDuple...

Using IDLE Line Detection + DMA on STM32L42x

In my opinion one of the simplest ways to receive an unknown amount of data has been this post which details how to use IDLE line detection to trigger the DMA to call the HAL_UART_RxCpltCallback function. This then reads the data received via UART fr...

I use STM32F030R8T8 programming with CUBE and TrueStudio. I have a problem with the frame error in UART communication on RS485 line. I have implemented the error_callback function to reset the error, but receiving remains blocked.

In a similar question it is recommended to carry out the instructions:void HAL_UART_ErrorCallback (UART_HandleTypeDef * huart){ // I implement this .. but eventually you can decide with different approach // Many macros / proc on this code .. is just...

Is here any reason for using HSE crystal with STM32L431 ?

Every L4 board that I've seen had footprint for HSE crystal routed but not populated. As I understand it is because MSI has automatic calibration on LSE clock. In my latest design I did the same - reserved place for HSE but marked it DNP. The 32.768k...
