System calls

buttonPushed()

Since 0.4.6:

Can be used to determine how long the System button (SETUP on Photon, MODE on other devices) has been pushed.

Returns uint16_t as duration button has been held down in milliseconds.

// EXAMPLE USAGE
void button_handler(system_event_t event, int duration, void* )
{
    if (!duration) { // just pressed
        RGB.control(true);
        RGB.color(255, 0, 255); // MAGENTA
    }
    else { // just released
        RGB.control(false);
    }
}

void setup()
{
    System.on(button_status, button_handler);
}

void loop()
{
    // it would be nice to fire routine events while
    // the button is being pushed, rather than rely upon loop
    if (System.buttonPushed() > 1000) {
        RGB.color(255, 255, 0); // YELLOW
    }
}
