STM32 General-purpose timer cookbook - Example of chapter 6.2 not working as intended
Hi everybody,I'm trying to test the examples of the General-purpose timer cookbook (AN4776) with a STM32 Nucleo-F446RE board and a breadboard with LEDs and resistors.This is my first time to use timers for PWM.I copied and adapted the code of chapter...
Correct way to clear TIM_SR_UIF after setting TIM_EGR_UG?
Hello,to update e,g. PSC before starting a timer, an update event has to be generated. This update event will set UIF and to avoid an interrupt from the update event, the UIF flag needs to be cleared. A sequence TIM1->EGR = TIM_EGR_UG; TI...
