Implemented Peripherals

This crate not yet done and support for a lot of peripherals is still missing. The following have been implemented already:

  • PORTB: Digital IO
  • PORTC: Digital IO
  • PORTD: Digital IO
  • PORTE: Digital IO
  • PORTF: Digital IO
  • TIMER0: 8-bit Timer/Counter0 with PWM
  • TIMER1: 16-bit Timer/Counter1
  • TIMER3: 16-bit Timer/Counter3
  • TIMER4: 10-bit High Speed Timer/Counter4
  • EXT_INT: External Interrupts
  • USB: USB Controller

If support for a peripheral you need is missing, please open an issue or implement it yourself and send a pull request ;)

Generating this crate

This crate is built using svd2rust. However, as there are no svd files available for ATmega32U4, a python script is used to generate the svd file. Take a look at gen-svd.py and svd/peripheral.py.

Peripherals can be specified in a toml format which should make adding new ones easier. Use the existing ones as reference (eg. svd/timer0.svd).

To actually perform a build, run build.sh.
