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

Ocassionally wrong CAN bit rate with STM32G0B1CBT3

I am trying to use a STM32G0B1CBT3 for standard (non-FD CAN communication).The device is running from a 8 MHz HSE oscillator.This is the clock topology I am using: As you see the CCS is disabled and the CAN clock and the system clock is running on 64

CAN messsages not transmitting even after successful return

Hello, hope you all are doing well.I am unable to transmit messages over CAN using DMA on my STM32G431RB Nucleo board. My JLink didn’t show any errors in my code flow, but my logic analyzer did not register any CAN messages on the TX pin (PA12), and

Raw Ethernet: How can I remove the CRC upon receipt?

Hello everyone, I have the following use case: I want to receive raw data via Ethernet, which works fine, but I have a problem: When I send 100 bytes, I only receive 14 bytes in my software on the MCU (STM32H7S3L8). I was able to fix this by settingA

Problems Erasing STLink IC on a Nucleo board

Hello,I have a Nucleo-L432KC with a dead microcontroller, but the STLink IC is ok.I wanted to use the STM32F103 to develop some USB code, so I removed the broken L432 and populated the reprogramming header for the SWD, CN2.I connected there a STLINK-

LoRaWAN_End_Node_LBM v1.5.0, US915, B-WL5M-SUBG1, TX Power Too Low - with possible solution

In testing the LoRaWAN_End_Node_LBM application supplied with STM32CubeWL-1.5.0 release I found that the output power is substantially lower than the same test setup with the LoRaWAN_End_Node application supplied with STM32CubeWL-1.4.0.  This te

Hello, I am working with X-NUCLEO-WB05KN1 together with NUCLEO-U083RC. I had previously tested U0 consumption in Stop mode and I got around 1.5uA (using 3.3V supply and LSI). From the datasheet it says that STM32WB05KZ should be an ultra low-power MC

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
