Struct microbit::display::MicrobitDisplayTimer

pub struct MicrobitDisplayTimer<T>(_)
 where
    T: Instance;

A TIMER peripheral programmed to manage the display.

MicrobitDisplayTimer instances implement the DisplayTimer trait.

The timer is set to 16-bit mode, using a 62.5kHz clock (16 µs ticks). The primary cycle takes 6ms.

Uses CC0 for the primary cycle and CC1 for the secondary alarm. Uses the CC0_CLEAR shortcut to implement the primary cycle.

Implementations

impl<T> MicrobitDisplayTimer<T> where
    T: Instance, 

pub fn new(timer: T) -> MicrobitDisplayTimer<T>

Returns a new MicrobitDisplayTimer wrapping the passed TIMER.

Takes ownership of the TIMER peripheral.

pub fn free(self) -> T

Gives the underlying nrf51::TIMERn instance back.
