Use of C language bitfields for device register I/O in STM32CubeC5

I noticed that stm32c5xx_hal_fdcan.c uses C language bitfields to access device registers. Since bitfields are compiler specific, every knowledgeable embedded software engineer knows that using bitfields to access device registers is non-standard and

Random SPI communication timeout with STM32H7 when reading sensor data continuously

I am working on an STM32H7-based project where I continuously poll sensor data over SPI in DMA mode. Everything works as expected for the first few hours, but occasionally the SPI bus freezes and triggers a timeout error (HAL_SPI_ERROR_TIMEOUT).Reset

RAM HAL library code relocation firmware update on single back flash controller (STM32G070)

Hi, I wrote a flash bootloader for STM32G070 using IAR ide.It gets via modbus RTU the command/data to manage the FSM that does the update procedure.Because the master during erasing/programming needs a real time update on overall progression, the .in

L6983 output is the same as the supply voltage

Hi, I have been trying to implement the L6983 in my design for about 4 month now and still don’t get the desired output. After checking the Fsw pin, it seems I don’t get any clock output, do you have any idea what would be the cause of this issue ? H
