getting embassy run and time-keeping

[djdisodo]

embassy_time driver for avr
example
patch for embassy

[djdisodo]

here's new version of the driver repo

this supports higher resolution for both Instants and scheduling

it uses TC1 instead

example code driving stepper motor

i found it 0.5ms step to be unstable not recommended

this code can run at the same time while other async code running

set source clock by changing feature on embassy_time_drvier
for example 16MHz(which uno uses)

[dependencies]
embassy-time-driver = { version = "0.1.0", features = ["tick-hz-16_000_000"]}

set prescalar with feature

[dependencies.avr_tc1_embassy_time]
path = "../avr_embassy_time"
default-features = false
features = ["prescalar64"]

embassy_time is very lightweight and you can use it even without embassy

so i'll recommend to use this crate even if you won't use async code
