Got a remote like this one?

Apple Remote

First, you’ll need an IR receiver.

Get a Vishay TSOP38438 or a similar. The important parameters are: operating voltage (3.3v), and carrier frequency (38kHz). Your receiver looks more or less like this:


Pins are numbered from 1 to 3 starting from the left with the lens facing up. Connect pin 1 to GPIO18 (pin 12) on the Raspberry Pi, pin 2 to any GND/ground pin (6, 9, 14, 20, 25, 30, 34, 39 on the Raspberry Pi), and pin 3 to any 3.3V pin (1 or 17 on the Raspberry Pi).

Enable the gpio-ir driver

Add the following to the end of your /flash/config.txt file:


Assign the correct keymap

The linux kernel reads flashes from the IR remote and needs to translate them into events readable by Kodi.

Paste the following into the following file - /storage/.config/rc_keymaps/a1156:

# table a1156, type: NEC
0x87eeda0a KEY_UP
0x87eeda0c KEY_DOWN
0x87eeda05 KEY_ENTER
0x87eeda06 KEY_RIGHT
0x87eeda09 KEY_LEFT
0x87eeda03 KEY_ESC

Set up the keymap to be loaded as default by pasting the following into /storage/.config/rc_maps.cfg:

* * a1156

Reboot your Pi

Your kodi instance, once loaded should now respond to your Mac remote.

Troubleshooting: Is my remote sending signals?

Grab your smartphone and turn on your camera. Then point the camera at the IR LED in the remote and press a button. You should see flashes - if not, your remote probably doesn’t work.

Troubleshooting: Does my IR receiver work?

Log into your Raspberry Pi and run ir-ctl -r and press some buttons on the remote. If you see a bunch of output like this, your remote is picked up by the IR receiver:
