Webrotary-encoder - a generic driver for GPIO connected devices. ¶. 14.1. Function ¶. Rotary encoders are devices which are connected to the CPU or other peripherals with two wires. The outputs are phase-shifted by 90 degrees and by triggering on falling and rising edges, the turn direction can be determined. Some encoders have both outputs low ... WebAug 18, 2015 · 2 Answers. Yes, that will work. I suggest you have something like a 1 kΩ resistor in series. That will limit the maximum current to 3.3 mA. That will save the day when by mistake you set both GPIOs as outputs, one as a 1 and the other as a 0. Without the resistor that would result in a damaging short circuit. It is perfectly ok to do this ...
