Hi everyone, I've done these steps before on STM32F0, STM32F1 and STM32F4 microcontrollers to detect when a circular DMA buffer for UART "wraps" (The counter finishes with the array and starts from the beginning again) with complete successActivated ...

I want to clear all pending interrupts in my bootloader before jumping to the user application, otherwise an interrupt will remain pending and therefore other interrupts wouldn't be triggered in the user application.After reading the Cortex-M datashe...

Good day everybody, I can't get this simple CAN reception with interrupt to work on my STM32F303VC microcontroller. I have probed the TX and RX lines of the receiving side with a logic analyzer and I saw no problem, however I don't get any interrupts...

Good day everybody,In my current application (IR signal generation) I need to change the PWM width for every bit that I want to send. In my implementation (seen below) I change the ARR and CCR1 values for the durations that I need, and then I generat...

I decided to run an experiment on my STM32F767ZI microcontroller. I turned on the cycle count register (DWT->CYCCNT) and decided to run the program step by step on Keil. I set the clock to the maximum amount possible with a PLL on this MCU, which is ...

This fixed my problem! Thank you! Forgot to clear the interrupt before jumping to the user application from the bootloader

This was the only method that worked for me, thanks!I also got stuck on the osSemaphoreAcquire(s_xSemaphore, TIME_WAITING_FOR_INPUT) line on the new version of STM32CubeIDE, and after increasing INTERFACE_THREAD_STACK_SIZE to 700, my code that used t...

Yup, this was the answer. The debugger was messing the clock up.I put 100 nops and decided to measure the DWT->CYCCNT between the start of the first one and the end of the last one, and ended up with a difference of 93.I don't know why it's not exact...
