UNO R3, Hairless MIDI Error: got unexpected data byte

Other Hardware Audio

Using the ardumidi.h library included with hairless bridge I get the error pointed at in the title plus an IDE Error stating:
"C:\Users\Utente\Documents\Arduino\libraries\ardumidi\ardumidi.cpp: In function 'void midi_command(byte, byte, byte, byte)':

exit status 1

Compilation error: exit status 1"

Here's the code:


#include <ardumidi.h>

// Wiring
const int potPin1 = A0;    // Potentiometer 1
const int potPin2 = A1;    // Potentiometer 2
const int buttonPin1 = 2;  // Button 1
const int buttonPin2 = 3;  // Button 2
const int ledPin = 4;      // LED

void setup() {
  // Com. Seriale
  Serial.begin(115200);

  // Bottoni Pull-Up
  pinMode(buttonPin1, INPUT_PULLUP);
  pinMode(buttonPin2, INPUT_PULLUP);

  // LED
  pinMode(ledPin, OUTPUT);
}

void loop() {
  // Lettura Valori Pot.
  int potValue1 = analogRead(potPin1);
  int potValue2 = analogRead(potPin2);

  //Scalatura
  int MIDIPot1 = map(potValue1, 0, 1023, 0, 127);
  int MIDIPot2 = map(potValue2, 0, 1023, 0, 127);

  // Status Bottoni
  int buttonState1 = digitalRead(buttonPin1);
  int buttonState2 = digitalRead(buttonPin2);

  // Controllo LED relativo a Bottone
  if (buttonState1 == HIGH) {
    digitalWrite(ledPin, HIGH);  // LED On
  } else {
    digitalWrite(ledPin, LOW);  // LED Off
  }

  // Invio MIDI
  if (buttonState1 == 1) {
    midi_note_on(0, 60, 127);
  } else {
    midi_note_off(0, 60, 0);
  }
  if (buttonState2 == 1) {
    midi_note_on(0, 64, 127);
  } else {
    midi_note_off(0, 64, 0);
  }

  midi_controller_change(0, 1, MIDIPot1);
  midi_controller_change(0, 2, MIDIPot2);

  // Delay
  delay(20);
}

I've been digging for days, reading stuff, I can't make it work and my exam is due in a week. Please, help me!

It looks like that arduimidi library is so out of date that it uses syntax for Serial.print() that was superseded many years ago. The BYTE parameter for Serial.print() is no longer supported, having been replaced by Serial.write()

I suggest that you find a later library unless you want to update the one that is causing the errors by editing it, which could be painful
