LED addresses for the A470

Hi all.

Anyone know the LED addresses for the A470? I errr.....thought i knew what they were....turns out I was wrong lol.

There a a few references to various programs that blink the A470 LED's (http://chdk.setepontos.com/index.php/topic,1602.0.html) for example. Any idea what blinker program MrSpoon is referring to in reply #7?

Thanks :)

I'd try
0xC022008C
0xC0220088
0xC0220084
0xC0220080

Found by looking for the string LEDCon, finding the function that uses it (sub_FFC3015C), leading to sub_FFCC3E14 which appears to set up a table of addresses and states.

Of course I could be wrong, if those addresses convert your camera to pure anti-matter, don't blame me ;)

Don't forget what the H stands for.

Hey, I just came on the check for A470 progress as it happens! I didn't keep note of all the LED addresses I found I'm afraid :-[

I mention one of them in this thread though and link to the blinker I was using :)

EDIT: Just in case anybody reads this thread, I've added which LED is at each address:

AF LED = 0xC0220080
Blue LED = 0xC0220084
Orange state LED = 0xC0220088
Green state LED = 0xC022008C
