Struct Delay

pub struct Delay { /* private fields */ }

System timer (SysTick) as a delay provider

Implementations

impl Delay

pub fn new(syst: SYST, clocks: Clocks) -> Self

Configures the system timer (SysTick) as a delay provider

Limitations

Depending on the core clock, this delay provider can delay between 1 minute (for 72 Mhz) up to almost 9 minutes (for 8 Mhz). Higher input values will be capped to these limits.

For accuracy purposes and because this is a blocking, busy-waiting function, if delays in the second to minute range are needed, use timers instead.

pub unsafe fn peripheral(&mut self) -> &mut SYST

Get access to the underlying register block.

Safety

This function is not memory unsafe per se, but does not guarantee anything about assumptions of invariants made in this implementation.

Changing specific options can lead to un-expected behavior and nothing is guaranteed.

pub fn free(self) -> SYST

Releases the system timer (SysTick) resource
