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