capsules_extra::screen::screen_on_led

Struct ScreenOnLedSingle

Source 
pub struct ScreenOnLedSingle<'a, L: LedIndexed> { /* private fields */ }
Expand description

A simple wrapper type to contain the index of the LED.

Since we don’t have a single GPIO pin to use, we instead store the index and call into the shared ScreenOnLed.
