2 buttons 4 functions help

I'm using my own button class here KTS_Button.h (3.3 KB) but you're welcome to write your own, use mine or just see how I'm doing it in my one:

I wouldn't claim that this is the best or the right way (just how I would approach it), but it does allow a set-up that's pretty easy to use and extend like this:

// Version 0.0

#define NUM_BUTTONS 2

#include "KTS_Button.h"

KTS_Button buttons[NUM_BUTTONS] = { 7, 6 };

enum Modes {
  RUN = 0,
  EDIT,
  NUM_MODES
}; Modes mode = RUN;

char* modeNames[NUM_MODES] = { "Run Mode", "Edit Mode" };

void cycleModes() {
    mode = mode + 1;
    if(mode == NUM_MODES)
      mode = 0;
    Serial.print(F("Mode Change: "));
    Serial.println(modeNames[mode]);
}

void printMessages() {
  switch(mode) {
    case RUN:
      Serial.println(F("Run Mode Short Press"));
    break;

    case EDIT:
      Serial.println(F("Edit Mode Short Press"));
    break;
  }
}

void setup() {
  Serial.begin(9600);
  buttons[0].setShortExecute(&printMessages);
  buttons[1].setLongExecute(&cycleModes);
}

void loop() {
  for (int i = 0; i < NUM_BUTTONS; i++) {
    switch (buttons[i].read()) {
      case SINGLE_PRESS:
        buttons[i].shortExecute();
        break;

      case LONG_PRESS:
        buttons[i].longExecute();
        break;
    }
  }
}
