* ONCHANGE(vpin) - flag when the rotary encoder position has changed from the previous position
* IFRE(vpin, position) - test to see if specified rotary encoder position has been received
*
* Further to this, feedback can be sent to the rotary encoder by using 2 Vpins, and sending a SET()/RESET() to the second Vpin.
* Feedback can also be sent to the rotary encoder by using 2 Vpins, and sending a SET()/RESET() to the second Vpin.
* A SET(vpin) will flag that a turntable (or anything else) is in motion, and a RESET(vpin) that the motion has finished.
*
* In addition, defining a third Vpin will allow a position number to be sent so that when an EXRAIL automation or some other
* activity has moved a turntable, the position can be reflected in the rotary encoder software. This can be accomplished
* using the EXRAIL SERVO(vpin, position, profile) command, where:
* - vpin = the third defined Vpin (any other is ignored)
* - position = the defined position in the DCC-EX Rotary Encoder software, 0 (Home) to 255
* - profile = Must be defined as per the SERVO() command, but is ignored as it has no relevance
*
* Defining in myAutomation.h requires the device driver to be included in addition to the HAL() statement. Examples:
*
* #include "IO_RotaryEncoder.h"
* HAL(RotaryEncoder, 700, 1, 0x70) // Define single Vpin, no feedback or position sent to rotary encoder software
* HAL(RotaryEncoder, 700, 2, 0x70) // Define two Vpins, feedback only sent to rotary encoder software
* HAL(RotaryEncoder, 700, 3, 0x70) // Define three Vpins, can send feedback and position update to rotary encoder software
*
* Refer to the documentation for further information including the valid activities and examples.
