/*
* CDJ-1000 MK3 Jog Wheel + Touch Sensor Test
* =============================================
* Board: Arduino Pro Micro (ATmega32U4, 5V/16MHz)
* Wiring: JOG1 → D2 (INT1 — hardware interrupt)
* JOG2 → D3 (INT0 — hardware interrupt)
* TCH → D4 (active LOW, pull-up on JOGB PCB)
* V+5 → VCC (5V)
* GND → GND
*
* Both encoder pins use hardware interrupts — no missed
* pulses even at full scratch speed.
*
* Touch sensor is a pressure-sensitive sheet switch (DSX1065)
* with 22kΩ pull-up (R2007) and 22nF debounce cap (C2002)
* already on the JOGB PCB. TCH is HIGH when not touched,
* LOW when platter is pressed down.
*
* Install: Sketch > Include Library > Manage Libraries >
* search "Encoder" by Paul Stoffregen (PJRC)
*
* Flash: Board = "Arduino Leonardo", then Upload as normal.
* Rename this file to .ino or add it to an .ino
* wrapper if your IDE requires it.

/* Encoder Library - SpeedTest - for measuring maximum Encoder speed

*/
// This SpeedTest example provides a simple way to verify how much
// CPU time Encoder is consuming. Connect a DC voltmeter to the
// output pin and measure the voltage while the encoder is stopped
// or running at a very slow speed. Even though the pin is rapidly
// pulsing, a DC voltmeter will show the average voltage. Due to
// software timing, it will read a number much less than a steady
// logic high, but this number will give you a baseline reading
// for output with minimal interrupt overhead. Then increase the
// encoder speed. The voltage will decrease as the processor spends
// more time in Encoder's interrupt routines counting the pulses
// and less time pulsing the output pin. When the voltage is
// close to zero and will not decrease any farther, you have reached
// the absolute speed limit. Or, if using a mechanical system where
// you reach a speed limit imposed by your motors or other hardware,
// the amount this voltage has decreased, compared to the baseline,
// should give you a good approximation of the portion of available
// CPU time Encoder is consuming at your maximum speed.
// Encoder requires low latency interrupt response. Available CPU
// time does NOT necessarily prove or guarantee correct performance.
// If another library, like NewSoftSerial, is disabling interrupts
// for lengthy periods of time, Encoder can be prevented from
// properly counting the intput signals while interrupt are disabled.
// This optional setting causes Encoder to use more optimized code,
// but the downside is a conflict if any other part of your sketch
// or any other library you're using requires attachInterrupt().
// It must be defined before Encoder.h is included.
