Resolved! FDCAN monitoring bus when MCU in sleep mode
Is it possible for STM32H5 to monitor the CAN bus when MCU is in sleep mode? Upon CAN bus activity detection, MCU automatically performing the wakeup sequence to be back in normal run mode.

Resolved! I2C Master_Transmit error because of NAK
My setup is as follows: I have a NUCLEO-H563ZI with an STM32H563ZIT6 and I am communicating through I2C with the 6D IMU, ISM330DCL. Moreover the ISM330DCL is on the STEVAL-MKI182V2.My I2C-bus is very confusing. First I get everything set up exactly a...
Resolved! One bit shift in SPI communication on STM32H7
I'm working on SPI communication between two Nucleo-H743ZI boards. I'm using ST's HAL, and the SPI polling API HAL_SPI_TransmitReceive.It's working fine until a bandwith of 12Mbits/s (SPI kernel clock at 200Mhz and prescaler 16, the CPU is always at ...
FUOTA IAP Updating Only Part of a Program
My goal is to implement an In-App Programmer (IAP) that can update part of our firmware from data we receive over a wireless network. We do not want to update the full firmware because it's too large and would take too long/consume too much power.I'm...
Resolved! Driving external shift register chain using USART as "SPI Master" - STM32L051
I have an application that requires a large number of digital outputs, but they can be very slow.The "true" SPI ports in my design are already in use for higher-performance peripherals, so my plan is to use a USART in synchronous mode to generate the...
STM32L4S5 Discovery Kit, how to use X-CUBE-AWS
I am doing various tests using the STM32L4S5 MCU board.Among them, I register this board with AWS and communicate with MQTT messagesTo do so, we connected to AWS using a package called X-CUBE-AWS provided by ST and actually communicated the sensor va...

Resolved! STM32F091 crashes during debug but runs normal without debugging
Hi everyone,I observed a strange behaviour while creating software for a STM32F091. I am using CubeIDE and HAL. FreeRTOS is used as well. The application is running as expected so far, but when I try to run it in debug mode it does not work. It crash...
STM32F405RGT6
Hi all, I have a flight controller which has a STM32F405RGT6 MCU and is working 100%.Another flight controller (different brand) has a damaged STM32F405RGT6 MCU and I would like to swap them instead of buying a new MCU online due to time constraints....
How to use center aligned PWM mode associated with Timer 1 in STM32G030x?
The following article helped us to use timers to trigger ADC conversions periodically. We now require to trigger ADC conversions at the centre of PWM pulse to get an accurate readings from ADC channels. Please help us with a solution to use center al...
