Hello,I would like to know if there is a possibility to readback the MPU confiugration for each configured region? HAL only provides a setter function. If I take a look into the internal implementation, it seems that regions get overwritten, when I ...

STM32H745I-Disco PWM Input Frequency Not detecting

Hi, I am trying to detect a 3v PWM frequency with my STM32, I have my live expresions setup for my variables, but the values do not budge from 0. Im sure it is something up with my code. Any help would be appreciated cheers.

Has anyone got any examples of how to read the built-in PDM microphone of the Discovery IoT Board (B-L475E-IOT01A)?

3-Wire SPI to demo board not working?

Good afternoon.I have configured SPI2 on STM32L476RG as Master Half Duplex, clock = 4MHz, CPOL = 1, CPHA = Edge 2. I am connected to a Pololu 2736 demo board (LSM6DS33). The timing diagram for the part shows resting clock as high (CPOL = 1) and MIS...
