Is it Possible to change the timer count direction dynamically without having to wait for it to over- or underflow?

2021-08-10
Hello dear ST-Community,here is a brief explaination of my problem:I'm using multiple stepper-motors in my system.I want to use 3 timers per stepper.Timer generates the PWM signal for the stepper-driver (easy to achive)Timer captures the signal of th...
