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 ...
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...
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...
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...

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...
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....
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...
Hi , I am using STM32L031x4 MCU for my project. In the document it shows 2 UART ports, can I use these 2 UARTS simultaneously ?I need 2 different UARTS for sensors.
I am using the MDK-ARM tool to develop our application.When I enable the "Trace Exceptions" function to trace all exceptions, it always show "No synchronization" in red below. And no exception can be seen from the table.I also uploaded the trace cloc...
