It's kinda ridiculous that seemingly three quarters of the people who write graycode decoder firmware get it wrong, despite the correct methods being publicly available with sample code since 15-20 years at least.

It's also an assignment that close to every electrical/computer engineer would have had to do as part of their degree.

I guess you only need to understand ~50% of the course material to get your degree though.

Sounds like clicky 3-pin A/B bi-phase type though. I’ve done stupid things and tried to read that and two buttons with single ADC. That jumped around when Vref fluctuates.
