ifndef DIGIMIDI_WRITEOUT

[apiel]

PR to be able to set #define DIGIMIDI_WRITEOUT 1 in order to define our own void usbFunctionWriteOut(uchar *data, uchar len) in the .ino file.

Example:

// NOTE Need to comment out usbFunctionWriteOut in DigiMIDI.h
#define DIGIMIDI_WRITEOUT 1

#include <DigiMIDI.h>

DigiMIDIDevice midi;
void setup() {
  pinMode(0, OUTPUT);
  pinMode(1,OUTPUT); //Pitch is output
  pinMode(5, OUTPUT); //Gate is output
  //Setup Timer1 to do PWM DAC for Pitch
  TCCR1 = _BV(PWM1A) | _BV(COM1A1) | _BV(CS10);
  GTCCR = 0;
  OCR1C = 239; //Set CV PWM range to 240
  OCR1A = 0; //Set initial Pitch to C2
  digitalWrite(5,LOW); //Set initial Gate to LOW;
  //*/
}
void loop() {
  midi.update(); //Check if any MIDI data is received  
}

void usbFunctionWriteOut(uchar *data, uchar len)
{
    uint8_t note = data[2]; // Get note for key on/off
    if (note < 36)
        note = 36;    // If note is lower than C2 set it to C2
    note = note - 36; // Subtract 36 to get into CV range
    if (note > 60)
        note = 60; // If note is higher than C7 set it to C7
    if (data[1] == 0x90)
    {                          // If note on
        digitalWrite(5, HIGH); // Set Gate HIGH
        digitalWrite(0, HIGH);
        OCR1A = note << 2;     // Multiply note by 4 to set the voltage (1v/octave)
    }
    if (data[1] == 0x80)
    {                         // If note off
        digitalWrite(5, LOW); // Set Gate LOW
        digitalWrite(0, LOW);
        OCR1A = note << 2;    // Multiply note by 4 to set the voltage (1v/octave)
    }
}
