Hi, I am now building a custom hardware based on 75_300_R3.
I'm very new to electronics design, so I have been struggling.
The problem now is duty cycle value looks very weird.
It seems oscillating when do nothing(no input, motor not running), and when I turn motor in one direction by hand I get strange value.
It should be like this↓
It would be grateful if anyone can give me any suggestions where to check.
