Struct riot_wrappers::led::LED

pub struct LED<const I: u8>(/* private fields */);

The Ith LED (calling the LED<I>_{ON,OFF,TOGGLE} macros).

The preferred interface for turning a LED on and off is switch_hal::OutputSwitch.

LEDs are accessible safely; any not implemented on a board are silently ignored.

LEDs are wrapped into embedded-hal 0.2 GPIOs for compatibility reasons (but that integration is discontinued with embedded-hal 1.0); GPIO is interpreted such that “high” is having the LED on, and “low” is off.
