LIRC/Ansible configuration for NAD amplifier

These configuration files were pulled from a much larger configuration and might not work out of the box in isolation, but hopefully can be helpful.

Assumes that an infrared LED is connected to the Raspberry Pi on GPIO pin 17. KiCAD files for a shield PCB are included in I tried using a commercial IR hat but it didn't work - it used a different pin which interfered with my sound card. A DigiKey parts list is included in parts.csv.

This is for a NAD SR712 amplifier. Configuration files for other devices can be found here. If you can't find the settings for your device you can try to reverse engineer the infrared protocol, I did this successfully for an unusual projector using an oscilloscope - it is possible!
