Enable

Turns the LED screen on and off

led.enable(false);

Parameters

  • on is a boolean that defines the on/off state of the screen

Example: Turning off the screen

This program turns off the screen when pressing button B

input.onButtonEvent(Button.B, ButtonEvent.Click, () => {
    led.enable(false)
});

Pins: P3, P4, P6, P7, P9, P10

These pins are coupled to the LED matrix display, and also its associated ambient light sensing mode. To disable the display driver feature (which will automatically disable the light sensing feature) call the DAL function led.enable(false). To turn the display driver back on again later, call led.enable(true).
