Variable frequency square wave generator 1hz to 100khz
2017年6月15日 · Hello All, I'm trying to feed the input pin on a M542T stepper driver with a square wave of variable frequency driven by a potentiometer. I'd like to drive i/o pin in the background somehow so that I can still have a larger number of lines of code running in the main loop without causing unwanted delays. I've tried a few approaches so far: digital write, delay, digital write, …
