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

avr-hal is a new approach to writing the HAL crate, that was designed with support for many AVR microcontrollers in mind. The macros have been factored out into a common crate named avr-hal-generic, which the board HALs then use to instanciate their respective peripherals.

Hardware Abstraction Layer for ATmega32U4. Built ontop of atmega32u4 for register definitions and embedded-hal for hardware abstractions.

The following features are implemented as of now:

• Port digital IO: Digital input and output using embedded-hal traits.
• Port PWM: Using the 4 builtin timers, PWM can be configured for a few pins. Namely PB5, PB6, PB7, PC6, PC7 & PD0.
• Delay: Delay using a busy loop. Implementation taken from the ArduinoCore library.
