This library provides a series of bindings for memory-mapped registers, peripherals, and many other functionalities related to AVR microcontrollers.

Any project using this library must use avr-gcc as its C backend.

NOTE: the contents of the library are highly experimental, they are not recomended for use in production code, APIs may break at any time!

nim >= 2.0.6

The nim modules that offer IO register mappings and ISR definitions are generated using the chips' datasheets as a reference.

The library currently supports the following chips:

• ATMega16U4
• ATMega32U4
• ATMega328P
• ATMega640
• ATMega644
• ATMega1280
• ATMega1281
• ATMega2560
• ATMega2561

nimble install avr_io

There are three main documentation sources for this project:

• The wiki hosted within the avr_io github page.
• The examples contained within the examples directory, that hosts a series of nimble projects ready to use and to be consulted, going quite thoroughly in detail on how to use the library.
• The in-comment documentation.

You can generate the documentation for this module and its submodules by running the following command from the root directory of the project:

nim doc --project --index:on -d:USING_ATMEGA328P --outdir:docs src/avr_io.nim

Note that you have to specify the microcontroller you are using, like when setting up the library.
