We are pleased to announce the release of the latest version IRLib 2 which now includes partial support for the Adafruit Trinket M0 and Adafruit Gemma M0 boards. IRLib2 is a library for Arduino and related boards that facilitates the receiving, decoding, and transmitting of infrared signals such as those used by TV remotes. The code is available on Github at https://github.com/cyborg5/IRLib2

All forms of input are available on any of the digital input pins. There are limitations however on the output pins. Neither of the boards support hardware PWM on the pin 1. So that support will not be forthcoming. Theoretically the Trinket M0 should be able to use pin 3 or pin 4 but for some reason we cannot get that code to work. Similarly the Gemma M0 should be able to do output on pin 2 but it does not work either. Both boards are configured to default output on pin 0 and that works fine. Alternately you can use pin 2 on the Trinket M0.

Anyone who can help us figure out what’s going wrong we deeply appreciate it. Feel free to email me or discuss the issue publicly on Github issue #44 links here. https://github.com/cyborg5/IRLib2/issues/44

Late Update February 9, 2018: Resolved problems with Trinket M0. It can now use pins 3 and 4. Thanks to Limor “LadyAda” Fried who found the problem. I defy you to name another electronics CEO who will take the time to debug someone else’s library. Another in a long list of reasons Adafruit is such an amazing organization. It turns out there never was a problem with the Gemma M0. My initial tests must’ve been wrong.
