We are pleased to announce that IRLib2 support for SAMD21 has been rewritten and greatly improved. It will allow us to and support for more boards using that processor much more easily.

Also the documentation available in Microsoft Word, Adobe PDF, and EPUB e-book format as received a major update. This is the first update or rewrite since the extensive 116 page manual was originally written.

The updated code and documentation are now available on GetHub at https://github.com/cyborg5/IRLib2

The user’s manual now includes extensive details about support for SAMD21 processors such as those used in Arduino Zero, Arduino MKR series, Adafruit M0 boards including the Circuit Playground Express. We’ve also shared online a Google docs spreadsheet that gives a handy reference to pin numbers we support on the SAMD21 processor. You might find it a useful reference for other purposes as well. The document can be found at https://docs.google.com/spreadsheets/d/1rY79Hfl4f9e5TQBas_rWI3LeyTD8Hr-lhqi349ZwVXU/edit?usp=sharing

The documentation now also includes an explanation of protocol 12 CYKM which facilitates IR transmission of mouse and keyboard commands. These are especially useful in creating assistive technology devices for the disabled.
