Crate atmega32u4_hal

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. Examples can be found in the port module.
• Port PWM: Using the 4 builtin timers, pwm can be configured for a few pins. For more info, take a look at the timer module.
• Delay: Delay using a busy loop. Implementation taken from the ArduinoCore library. Examples in the delay module.

Easy Globals

Because a lot of times you need to exchange data between your application code and interrupt handlers, this crate contains a safe abstraction for globals. While a global is accessed interrupts are disabled, so you don't need to worry about data races. For more info, take a look at the global module.

Re-exports

pub extern crate embedded_hal as hal;

pub use global::Global;
