WebSep 26, 2024 · According to my cheap handheld oscilloscope the frequency is stuck at 60Hz even if I change OCR2A. I can't explain why. Then there's a problem with the duty cycle. If OCR2B is at 6 the duty cycle is at ca. 13%. If OCR2B is at 37 the duty cycle is close to 0%. I expected the duty cycle to be much higher the lower OCR2B is. Why is this not the case? WebIn theory a square wave has an instantaneous rise and fall. But it has a dwell time based on the frequency. Lets take a 1 hz square wave. The signal goes from zero to 100% [1] in an …
