// Decoder TEST v0.21 -- Andrew Micklich -- September 2016
// ------------------------------------------
// SETUP:
// Connect Arduino MEGA digital pins 22-29 to D0-D7 on the HTCL
// Connect digital pin 31 to X/Y
// Connect digital pins 33 and 32 to EN1, EN2 respectively
// Connect digital pin 34 to SEL2
// Connect digital pin 36 to SEL1
// Connect digital pin 35 to RSTX
// Connect digital pin 30 to RSTY
// Connect digital pin 36 to OE
// Connect digital pin 38 to CLK
// Connect 5V Arduino pin to 5V input on optical encoder and V_DD on HTCL
// Connect GND Arduino pin to GND on optical encoder and V_SS on HTCL
// Connect Channel A on encoder to CHA_X on HTCL
// Connect Channel B on encoder to CHB_X on HTCL
// NOTE: Index Channel not yet supported in code
// TEST TEXT
// --------------------------------------------
// Known Bugs:
// None
// --------------------------------------------
// Known Limitations:
// If encoder is turned too rapidly, will not record (Hardware limits? Clock limits?)
// Only 16-bit count currently, eventually can support 32-bit if necessary
