Detecting headphone events on kindle touch

[inuxy]

Where am I able to detect certain events on the kindle? I would like to make a script that listens for these events. One event I would be interested in is when a headphone jack is inserted.

The easiest way is to have your script call "waitforkey". To find all the keycode events, try causing events while this command is running in SSH:

while :;do waitforkey;done

It will show unique keycodes for headphone insertion and removal. On 5.0.x firmware (which booted up with the accelerometer enabled), waiforkey will even show keycodes for rotation events.

Headphone events only seem to generate waitforkey keycodes in K5 diags in the latest firmware update. Rotation events also return keycodes from K5 diags. That is where I tested my scripts in the past because diags has a lot more free RAM than main.

It appears that in main (K3 and K5), events like headphone insert/remove are not detected. It would be interesting to see if copying waitforkey from K5 diags to other bootmodes or devices would work.

I just copied the K5 diags waitforkey to /mnt/us, then I rebooted to main. From main, the diags waitforkey does not return headphone events, so it must depend on library or kernel support. Bummer...

Since it's now using X, anyone checked if X gets any of these events (via something like xev)?
