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

STM32CubeMX2 Failing to Start

I am running STM32CubeMX2 (1.1.1) on a Mac (Tahoe 26.6.2) and I did (with some difficulty) get it installed and running. I configured a MCU (STM32C552CEUx) and generated an STM32CubeIDE project. No problem.I went back and copied the .ioc2 file, renam

CRC – trouble understanding bit reversal

I’ve trawled through several CRC-related threads without finding an explanation of this: How to properly set up bit reversal.Normally, I use CRC-16 XMODEM, which uses the 0x1021 polynomial and no bit reversal. This works perfectly fine when I use thi

How to move a project to a new directory?

I would like to move the project from:C:\ST\STM32Cube_FW_WB_V1.24.0\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_HeartRateFreeRTOSto:C:\Projects\Myprojectso that I can make modifications at will and not worry about corrupting the original code.

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

HAL2 User Data pointers tp *non* const

This is a feature request.In HAL2, we can configure an STM32CubeMX2 project to use User Data pointers (pointers managed only by the application, not the HAL2 library). E.g. setting USE_HAL_UART_USER_DATA to 1 will add the field `const void *p_user_da
