Very cool - and even cooler (IMHO), while digger around related things on the web I found CHDK (http://scratchpad.wikia.com/wiki/CHDK) - a hack for C***n DIGIC II based cameras that enables raw mode, live histogram, live over/under exposed indications, *scripting* and a whole host of other stuff.


I have an A620 sitting on my desk here just waiting for me to have time to give it its dose of steroids...

Ok, looks like that will be RC5 code 0,0 (just like Matt said above sometimes works).

I presume it's sometimes because RC5 has a modulation of 36khz, not 38 and the bits are ~0.85ms on then 0.85ms off. Close to the pentax code, but not exact. RC5 doesn't have the long intro that the pentax sequence has, but it will have at least more of the ~1ms on/off repetitions than needed.

Interestingly there's this code on remote central marked up as wide/mid/tele for pentax cameras

0000 006E 0008 0000 01EE 0072 0026 0026 0026 0026 0026 0026 0026 0026 0026 0026 0026 0072 0026 0026

This is roughly the same as Matt's sequence, but with a long 'off' in the 2nd to last repeat. I wonder if the 7 on/off repeats encode 7 bits of info, with a zero being ~1ms on, 1ms off and a 1 being ~1ms on, 3ms off.

That would give me 128 codes to try to see if they do anything interesting

What make and model of TV? With luck I can pull the remote codes for it from the internet and see if a) it does the same on the K10D and b) is there a pattern that might enable more codes to be found...

cheers,

The burst cycle that Matt describes corresponds to the following Philips Pronto IR Code:

0000 006C 0008 0001 01F0 0073 0026 0026 0026 0026 0026 0026 0026 0026 0026 0026 0026 0026 0026 0026 0099 250D

This works fine triggering my K10D using my Pronto.

I know that there are various other learning/programmable remotes that can utilize Pronto IR codes (sometimes after conversion by a utility application), so hopefully this will prove useful to others.

Cheers Matt!
