Required Methods§

source

fn regs() -> TimBasic

Get access to the basic 16bit timer registers.

Note: This works even if the timer is more capable, because registers for the less capable timers are a subset. This allows writing a driver for a given set of capabilities, and having it transparently work with more capable timers.

Provided Methods§

source

fn start(&mut self)

Start the timer.

source

fn stop(&mut self)

Stop the timer.

source

fn reset(&mut self)

Reset the counter value to 0

source

fn set_frequency(&mut self, frequency: Hertz)

Set the frequency of how many times per second the timer counts up to the max value or down to 0.

This means that in the default edge-aligned mode, the timer counter will wrap around at the same frequency as is being set. In center-aligned mode (which not all timers support), the wrap-around frequency is effectively halved because it needs to count up and down.
