We are pleased to announce that IRLib2 has now added support for the SAMD51 processor on the Adafruit Metro M4. Other M4 platforms will be supported as they become available.
The SAMD51 processor runs at 120 MHz. It has 512 KB flash and 192 KB RAM. This is a much more powerful processor than the M0 class SAMD21.
We support PWM output on pins 0-13 and input on any digital input pin.
The code is currently available on Github at https://github.com/cyborg5/IRLib2
