Arduino M5Core2 Buttons

SirMichael

I'm having trouble understanding how to use the M5Stack Core2, creating new buttons for my project.

I can use the 3 buttons (A, B & C) and for some screens, I need two more buttons, with similar properties.

I've been studying the Example: events_buttons_gestures_rotation.ino but I can't make heads or tails of it. I've added print statements to see which subroutines are executed and I don't understand what the "doRotation()" or what the swipe gestures do.

The only thing that I've discovered in playing with it is that if I press one of the buttons twice quickly that the "toggleColor" is executed.

The few comments are useless to me.

Is there a simpler example somewhere that I can use to create a few buttons when I need them for the "wasReleased()" and "wasPressedFor()" functions?

I found what I was looking for, a simple sketch to create a button. I did some minor massages, taking from the events_buttons_gestures_rotation.ino and figured it out.

#include <M5Core2.h>

ButtonColors on_clrs = { RED, WHITE, WHITE };
ButtonColors off_clrs = { BLACK, WHITE, WHITE };
Button myButton(10, 10, 80, 60, false, "Button", off_clrs, on_clrs, TL_DATUM );

void setup() {
  M5.begin();
  M5.Buttons.draw();
}

void loop() {  
  M5.update();
  if (myButton.wasReleased()) Serial.print("* ");
  
}
