Deprecation Note:

This crate will soon be deprecated in favor of avr-device.

The approach of generating the svd from hand-written register definitions has proven to be way to tedious to be scalable. In avr-device, we base our work on atdf files provided by Atmel(Microchip). This allows much faster growth of the list of supported devices (and peripherals). Please head over there if you want a register-access-crate for AVR microcontrollers.

`ATmega32U4`

Low level access to ATmega32U4 registers. Refer to the ATmega32U4 datasheet for more detailed information.

Implemented Peripherals

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

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