Hello to all.
I’m working on a mod for the Jay-D so we can use it as a MIDI controller.
I want to try the Bluetooth functionality and the first test code is working.
I used the ESP32-BLE-MIDI library https://www.arduino.cc/reference/en/libraries/esp32-ble-midi/.
My problem now is to have a working code to listen faders/encoders/buttons values change.
I tried to use classic Arduino coding like “Serial.print(analogRead(37))” since from the schematic one fader is connected directly to the analog pin 37 on the ESP32 but I don’t get anything on Serial Monitor.
This is the only working code that shows faders’ values on Serial Monitor.
But it doesn’t send those values thru MIDI protocol.
#include <Arduino.h>
#include <BLEMidi.h>
#include <CircuitOS.h>
#include <JayD.h>
#include <Loop/LoopManager.h>
#include <Input/InputJayD.h>
int valuePotLrec;
int valuePotRrec;
int valuePotMrec;
byte midiNote = 0;
void potentiometer_POT_L_moved(uint8_t value){
valuePotLrec = value;
midiNote = map(valuePotLrec, 0, 255, 0, 127);
BLEMidiServer.noteOn(0, valuePotLrec, 127); //Start sending Left fader value thru MIDI as a note
delay(1000);
BLEMidiServer.noteOff(0, valuePotLrec, 127); //Stop sending Left fader value thru MIDI as a note
delay(1000);
Serial.print("POT_LEFT: ");
Serial.println(valuePotLrec);
}
void potentiometer_POT_R_moved(uint8_t value){
valuePotRrec = value;
Serial.print("POT_RIGHT: ");
Serial.println(valuePotRrec);
}
void potentiometer_POT_MID_moved(uint8_t value){
valuePotMrec = value;
Serial.print("POT_MID: ");
Serial.println(valuePotMrec);
}
void setup() {
Serial.begin(115200);
Serial.println("Initializing bluetooth");
BLEMidiServer.begin("BLE MIDI JAYD");
Serial.println("Waiting for connections...");
JayD.begin();
//pinMode(PIN_BL, OUTPUT); digitalWrite(PIN_BL, LOW);
InputJayD::getInstance()->setPotMovedCallback(POT_L, potentiometer_POT_L_moved);
InputJayD::getInstance()->setPotMovedCallback(POT_R, potentiometer_POT_R_moved);
InputJayD::getInstance()->setPotMovedCallback(POT_MID, potentiometer_POT_MID_moved);
}
void loop() {
LoopManager::loop();
/*THIS IS THE MIDI THRU BLE LIBRARY'S EXAMPLE CODE
* if(BLEMidiServer.isConnected()) {
midiNote = map(valuePotLrec, 0, 255, 0, 127);
BLEMidiServer.noteOn(0, midiNote, 127); // If we've got a connection, we send an A4 during one second, at full velocity (127)
delay(1000);
BLEMidiServer.noteOff(0, midiNote, 127); // Then we make a delay of one second before returning to the beginning of the loop
delay(1000);
