Struct teensy4_bsp::SysTick

pub struct SysTick(_);

This is supported on crate feature systick only.

A type that represents the system timer, SYSTICK

SysTick implements the embedded_hal's DelayMs trait. It may be used to implement simple, blocking delays.

Example

use teensy4_bsp as bsp;

let core_peripherals = cortex_m::Peripherals::take().unwrap();
let mut systick = bsp::SysTick::new(core_peripherals.SYST);

systick.delay(50 /* ms */);

Implementations

impl SysTick

pub fn new(systick: SYST) -> SysTick

Convert the normal cortex-m SYST peripheral into a Teensy SysTick

new will configure the systick counter for a 1ms tick. When new() returns, systick is counting.

Safety

new is safe because it assumes that it has the only SYST instance. The only way you could acquire two SysTick is if you've unsafely obtained a second SYST instance.

pub fn delay(&mut self, ms: u32)

Blocks for ms milliseconds
