STM32 Blue Pill Timer PWM Mode with LED Dimmer Example

WebNow, given that the entire PWM range (0% up to 100%) has a 16-Bit of resolution or 65536 discrete levels. The motor rotation range is (12% – 3% = 9%) and this 9% has (9/100)*65536 discrete levels of control. This means that the servo motor’s angular range (0° up to 180°) is mapped to nearly 5900 discrete levels. WebJan 24, 2024 · The full story is that I found this problem a few years ago, occasionally the timer interrupts would come way too early. That's when I found that the interrupt flag sometimes got set when TIMx->CCRx was assigned. I solved that by always clearing the interrupt flag right after assigning TIMx->CCRx. tsb account terms and conditions
