Description | The Wiring encoder library provides for 4 encoder channels, so it can drive up to 4 encoders at a time. The encoder's phaseA cable can be connected to digital I/O pins 2, 3, 38 or 39 exclusively, on the Wiring I/O board. This is because the library is based on external interruptions which can only happen on these specific pins. The phaseB cable can be connected to any other digital I/O pin of the Wiring I/O board. The attach(phaseAPin, phaseBPin) method attaches an Encoder variable to the pins where the encoder is connected. | ||||||
