// An example sketch using the joystick library, demonstrating multiplexer support
// In this example, we have 21 buttons we want to attach.
// Unfortunately, the Arduino Uno only has 17 pins we can use!
// So we've added an 8-channel multiplexer, connected to pins A1-A5.
//
// Note: this may not be the best approach for this many simple buttons. Using an input matrix
// would require as few as 10 inputs in this scenario, for example. This is just a demo :)
#include <Joystick.h>

// All of our digital pins and A0 are taken up with pushbuttons

// to get more room for our inputs, we add an 8-bit multiplexer
uint8_t mux = joystick.AddMux(A1, {A2, A3, A4, A5}, 4);
// now we can add the rest of the buttons
joystick.AddButton(A1, BUTTON_PASSTHRU, true, true, mux, 1); // the last parameter is which channel/pin the input is attached to on the multiplexer
