Momentary Button Toggle

[cferrarini]

I want to adapt DigitalCC class to use a momentary button as toggle, this was written only for an on/off switch. Can anyone help with the code? Thanks Celso

include "DigitalCC.h"

include "MIDI_Controller.h"

using namespace ExtIO;

DigitalCC::DigitalCC(pin_t pin, uint8_t controller, uint8_t channel) // Constructor : pin(pin), controller(controller), channel(channel) { ExtIO::pinMode(pin, INPUT_PULLUP); // Enable the internal pull-up resistor on the pin with the button/switch }

DigitalCC::~DigitalCC() { // Destructor ExtIO::pinMode(pin, INPUT); // make it a normal input again, without the internal pullup resistor. }

void DigitalCC::invert() // Invert the button state { invertState = true; }

void DigitalCC::refresh() { // Check if the button state changed, and send a MIDI CC accordingly bool state = ExtIO::digitalRead(pin) ^ invertState; // read the button state and invert it if "invert" is true

if (millis() - prevBounceTime > debounceTime) { int8_t stateChange = state - buttonState;

if (stateChange == falling)
{ // Button is pushed
  buttonState = state;
  MIDI_Controller.MIDI()->send(CONTROL_CHANGE, 
    channel + channelOffset * channelsPerBank, 
    controller + addressOffset * channelsPerBank, 127);
}

if (stateChange == rising)
{ // Button is released
  buttonState = state;
  MIDI_Controller.MIDI()->send(CONTROL_CHANGE, 
    channel + channelOffset * channelsPerBank,
    controller + addressOffset * channelsPerBank, 0);
}

} if (state != prevState) { prevBounceTime = millis(); prevState = state; } }
