it seem that Cameras with chdk currently running clear a bit in

physw_status[1]

when a key is press

read here for more what values a SX210 bring

http://chdk.setepontos.com/index.php?topic=5722.msg56662#msg56662

but the ixus 1000 HS we now want to get working, set the bit when a key is press.see here the key values

http://chdk.setepontos.com/index.php?topic=5722.msg56510#msg56510

and for the IX1000 HS this code for example work wrong and return 0 when a key is press and 1 when no key is press for every key that is check

long kbd_is_key_pressed(long key) {
    int i;
    for (i=0;keymap.hackkey;i++) {
        if (keymap.hackkey == key) {
           // return ((kbd_new_state[keymap.grp] & keymap.canonkey) == 0) ? 1:0; // default chdk code, work not for IX1000HS
          return ((kbd_new_state[keymap.grp] & keymap.canonkey) == 0) ? 0:1; // work for IX1000HS
        }
    }
    return 0;
}

but there need other functions in platform.... kybd.c change to get it work.
Are there Cameras that work in same way as IX1000 HS ?

maybe DSLR ?

If somebody have such a problem the wrong pysw_status address is used.there seem more addresses here that store keyboard values.

you need use the address that clear a bit on keypress

when use in 100d this seem correct.
 
DEF(physw_status, 0x34408)                 // found at FF834B8C

i see now when a key is not press all bits are set.
I see also that SD card write protect can now see too

I am happy that this cam is not diffrent and hope can get the keyboard soon correct working and maybe the Video key can work as alt key
