How to find WiFi LED address?

Hi,

I want to use the WiFi LED of my S110 to generate a feedback signal back to my microcontroller.
It is a blue LED, do you think I can 'read' it proplerly by a fotodiode?
Is the address of the S110 WiFi LED already known? If yes what is the address please?
If not, how can I analyse the S110 firmware to find this address?

Thanks for any help!

According to the comments should be controllable with the camera_set_led function, see http://trac.assembla.com/chdk/browser/trunk/platform/s110/lib.c

I would guess this is also used for the debug LED, but if not the address should be nearby.

Note that by default the CHDK will blink the debug led in various situations (like saving raw) which might throw off your communication system. You could avoid this by making the debug_led function do nothing.
Don't forget what the H stands for.
