Controller LEDs

Read state

read-led-state.gpc

int led_state;

main {
    led_state = get_led(LED_1);
    set_val(TRACE_1, led_state);
}

States are 0..3: off, on, fast blink, slow blink.

Set state

init {
    set_led(LED_1, 1);
}

Finite blink count

finite-blink-count.gpc

main {
    if(event_press(PS5_CROSS)) {
        set_ledx(LED_1, 3);
    }

    set_val(TRACE_1, get_ledx());
}

get_ledx() reports whether a finite sequence is active. A blink count of zero leaves the LED on.

Return control to the console

main {
    if(event_press(PS5_CIRCLE)) {
        reset_leds();
    }
}
