# Setup
|
||
|
|
|

This describes getting a silver apple remote (A1294) working with a headless piCorePlayer. It requires `v5.0.0`, which includes fixes for how `squeezelite` is called so that it finds the `~tc/.lircrc` file.
|
||
|
|
|
||
|
|
I'm using it with an IQaudio DAC+ with a 3-pin header soldered into the appropriate holes.

LIRC has a git repository, [lirc git repo][lirc-git], but unfortunately its web-based git browser isn't working. If you clone the repo, you'll find a [configuration document][lirc-config] that's interesting reading.
|
||
|
|
|
||
|
|
The [LIRC project web site][lirc] includes a database of `lircd.conf` files for various remotes that includes entries for the silver and white apple remotes. **BUT**, they're for an older version of LIRC and don't work with the piCorePlayer version. I found functional versions on the net for the [A1294][lirc-a1294] and the [A1156][lirc-1156] (*untested).

[Squeezelite][squeezelite] uses the [lirc_client][lirc-client] API to interact with LIRC. It compares events that it receives with a set of cmds from the "squeezeplayer" remote and then from a table populated from a `.lircrc` file. When piCorePlayer has LIRC installed and you've uploaded a custom `lircrc` file, squeezeplayer is run with the `-i /home/tc/.lircrc` option.

# Debugging
|
||
|
|
|
||
|
|
1. use `sudo mode2 -d /dev/lirc0` to see the raw events coming from LIRC. This is the lowest-ish level and will confirm that you have the kernel bits in place and the hardware wired up correctly.
|
||
|
|
2. use `irw` to dump the higher level events (e.g. `KEY_OK`), which confirms that you have a `lircd.conf` file that works for your device.
|
||
|
|
3. enable ir debug (or sdebug?) output in the piCorePlayer squeezelite page and watch the log file (e.g. ssh into the pi at `tc` and `tail -f /var/log/pcp_squeezelite.log`) to see what squeezelite is doing with the events.
