Resolved! STM32L031 RTC Wake up interrupt service routine never entered

TL;DR: I see that the WUTF bit in RTC ISR register is correctly set after the RTC wake up timer period elapses, but the interrupt service routine is never entered. RTC interrupt is enabled in NVIC though, and the interrupt service routine function na...

H-bridge control with PWM from different timers and channels

I would like to point out that I'm fairly new to STM programming and SMT32CubeIDE, but I have a problem to solve that I need help with:I am making a speed controller for a 3-phase BLDC motor, with 6 N-channel mosfets (two for each phase). These mosfe...
