Struct Fwdgt 

pub struct Fwdgt { /* private fields */ }

The watchdog before it is started, the only state its period can be set in.

Implementations

impl Fwdgt

pub fn start(self, psc: FwdgtPsc, rld: u16) -> FwdgtRunning

Sets the period and starts counting down; there is no way back.

The timeout is (rld + 1) ticks of IRC40K / psc. Blocks while the dividers reach the counter, which runs at 40 kHz.

Panics

If rld exceeds 12 bits.

pub fn start_timeout<const NOM: u64, const DENOM: u64>( self, timeout: Duration<u32, NOM, DENOM>, ) -> FwdgtRunning

Same as start, but takes the period as a duration and picks the dividers itself.

Any scale works with no conversion at the call site — 2.secs(), 500.millis(). Truncating, so the realised timeout is at most one tick short of the request; anything past 26 s saturates there, and zero becomes one tick.
