Can I use the analog multiplexer library of 8, to connect one of 16? #94

Closed Xicury closed 4 years ago

Xicury commented 5 years ago

Greetings I have a question friends, I try to use the MIDI_Controller library to use the digital multiplexer to connect 16 potentiometers in a 16-output analog multiplexer, I see that the library codes only have 1 analog and 3 digital pins for communication, in my In case my multiplexer has 4 digital for communication with the 16 channels, my question is, could the multriplexer work with the library codes simply by increasing that pin to the library code?

----------------------------------------------ORIGINAL CODE-----------------------------------------

include // Include the library

// Create an instance of 'AnalogMultiplex' with the output pin of the multiplexer connected to // analog input pin A0 and the address pins connected to pins 2, 3 and 4. AnalogMultiplex multiplexer(A0, { 2, 3, 4 } );

// Create 8 new instances of the class 'Analog', on the 8 pins of the multiplexer, // that send MIDI messages with controller 7 (channel volume) on channels 1 - 8 Analog potentiometers[] = { {multiplexer.pin(0), MIDI_CC::Channel_Volume, 1}, {multiplexer.pin(1), MIDI_CC::Channel_Volume, 2}, {multiplexer.pin(2), MIDI_CC::Channel_Volume, 3}, {multiplexer.pin(3), MIDI_CC::Channel_Volume, 4}, {multiplexer.pin(4), MIDI_CC::Channel_Volume, 5}, {multiplexer.pin(5), MIDI_CC::Channel_Volume, 6}, {multiplexer.pin(6), MIDI_CC::Channel_Volume, 7}, {multiplexer.pin(7), MIDI_CC::Channel_Volume, 8} };

void setup() {}

void loop() { // Refresh the MIDI controller (check whether the potentiometer's input has changed since last time, if so, send the new value over MIDI) MIDI_Controller.refresh(); }

You should be able to just pass 4 pin numbers to the constructor.
