LED control seems to work fine and I added my personal touch :p but strange as it seems, the blue (DP) led isn't PWM, while the AF and tally led are  ??? Ah well :)
Edit: on the S5, obviously.

I noticed that that on the SD series, to turn on the blue LED, it is a 2-step process of writing to two memory locations.  This may be due to the higher voltage requirements for blue LED's - they may have a separate power supply for the blue LED that also needs to be controlled.

Party-cam 8)

I tried PostLEDMessage on my A720, it works fine, I can control all the LEDs (copied ewavr's code, cheers to him) but only AF can control brightness. Useful values for brightness range from 30 to 100.

Changes are in trunk.

Cheers.

I can see it now, a thief picks up your camera and it starts playing, "STEP AWAY FROM THE CAMERA. PUT IT DOWN AND STEP AWAY FROM THE CAMERA! This camera is going to self destruct in 30 seconds after all the lights start flashing!"

and I can see the thief throwing your camera far away and running :-)

In German sounds: "AUA"!!
I already fired a half way empty flash cap to my finger. :'( (from old camera, batteries removed, flash fired, ...)
And it wouldn't work for A-Series as the only metal part is the lens ...
And you're sure it wouldn't disturb the camera?  :haha another old cam died of it's own flash, because the paper protecting the rest of the pcb was attached in a wrong way.
