STM32U5 FDCAN version

Hello all,we intend to use the STM32U5 in a project that uses CAN FD. I have learned that the initial CAN FD version 1.0 specification from Bosch [1] in 2012 had a bug that prevented the CRC detecting some error types, which led to changes during the...

printf and float

So, I'm having an issue getting the printf() function suite to work with floating point values.First, understand that I am not using STM32CubeIDE. It's a good tool, but I've had too many issues/complications using it. I use a custom Makefile and VSc...

I want to write a program for the STM32F303VC board that uses SPI interface to make a comunication between the MCU and the L3GD20 gyroscope and read the values of the 3 axis.

The results are always the same: x=-6.145, y=-6.149, z=-6.149 , even if I move my board. What's wrong?#include <stm32f30x.h>void GPIO_Config();void SPI_Config();uint8_t L3GD20_Read(uint8_t reg);void L3GD20_Write(uint8_t reg, uint8_t data);void L3GD20...
