Using Mechanical Rotary Encoders with PIC microcontrollers. Chipkit boards have limited support. The intent of this article is not to rehash a well known concept, but to show the particulars of my implementation. Incremental encoder interfaces commonly use a quadrature decoder to convert the A and B signals into the direction and count enable (clock enable) signals needed for controlling a synchronous, bidirectional (up- and down-counting) binary counter. These A and B channels (quadrature) are defined as pulses per revolution (ppr) and define the smallest. Notice also how A and B channels and the Z pulse are formed with the transparent parts. A counter with quadrature decoder as well as a latch for the zero impulse can be read or enabled by the control. Incremental Encoders : An encoder is an electrical mechanical device that converts linear or rotary displacement into digital or pulse signals.
