Keyboard does work now with a little workaround because SD4000 has no Print Key. I need to find a way to use Key combination to enter ALT mode like (SET+UP).

I changed kbd.c like SX110, because camera did shutdown when overwrite physw_status (kbd_fetch_data() did return wrong values).

Now Camera does shutdown if you enter CHDK menu.  >:(

Regular CHDK Logo works again.

CHDK Display is still in Greyscale.

Finally, CHDK Menu does work!!  :D

Fixed some wrong stubs while compare to SX210 beta in my code and SX210 code  ;)

Tested:
  • Keyboard
  • Textreader
  • some Scripts
  • Calendar
  • Games (but with wrong color)
  • Debug Stuff and Memory Browser

Using KEY_LEFT as ALT Button is a bit annoying...

Fixed ALT mode key by using BIT mask for two Keys: KEY_UP +  KEY_LEFT. This means user has to press both buttons to enter CHDK.

kbd.c
Code: (c) [Select]
// Base values in Play Mode
// physw_status[0] = 0x800C91F      // 1
// physw_status[1] = 0xFFE          // 2 (Mode Switch: Auto)
// physw_status[2] = 0x400000       // 3
// Mode Switch:
// physw_status[1] 0x1 Auto
// physw_status[1] 0x0 Photo
// physw_status[1] 0x2 Video
// physw_status[2] 0x20000 SD-Card READONLY
static KeyMap keymap[] = {
    { 0, KEY_UP         , 0x00000004 },
    { 0, KEY_DOWN       , 0x00000001 },
    { 0, KEY_LEFT       , 0x00000008 },
    { 0, KEY_RIGHT      , 0x00000002 },
    { 1, KEY_SET        , 0x00000040 },
    { 0, KEY_SHOOT_FULL , 0x00000800 },
    { 0, KEY_SHOOT_HALF , 0x00000100 },
    { 1, KEY_ZOOM_IN    , 0x00000010 },
    { 1, KEY_ZOOM_OUT   , 0x00000020 },
    { 1, KEY_MENU       , 0x00000080 },
    { 0, KEY_PRINT      , 0x0000000C },   // ALT Key workaround: KEY_UP +  KEY_LEFT (camera has no print key)
    { 0, 0, 0 }
};
This also means theres no need for alt_mode_key_mask.

Still canon firmware has redraw issus sometimes before and after ALT mode (redraw recovers after some seconds most of the time).

Beta v1 is available

Here is Beta v1 if somebody want to test it...

http://drop.io/chdk_ixus300_sd4000

Please write you feedback here.

Edit: Only "Firmware Update" chdk start does work yet. ALT-Keys are UP+LEFT (press them together).

Any idea how to "fix" the different color palette?

CHDK does actually can display colors, but default chdk color does not "fit"...

Code: [Select]
http://pixeldoc.kicks-a ss.net/projects/chdk/ixus300_sd4000/canon_ixus300_sd4000_color_palette.jpg
Weird thing is, chdk does even use different color pallette in play and rec mode on this camera...

Code: [Select]

Not CHDK using a different palette, the canon firmware does this. It's quite common.

To "fix" the palette for CHDK, look at gui_draw.h and pick values that make the displays usable. Try the already defined palettes first to see if one works.

Don't forget what the H stands for.

pixeldoc,
try changing the diferente palette numbers is camera.h

Code: [Select]
#define CAM_BITMAP_PALETTE    5

Some questions about your status:
-Do the overrides in taking pictures work?
-The pictures are blurry?  -> If so check this: http://chdk.setepontos.com/index.php/topic,5045.msg54835.html#msg54835
-Raw?

I already though it depents on canon firmware

Looks like no CAM_BITMAP_PALETTE match perfectly... I'll have to do more testing.

I've tested them, no one seems to fit...

capt_seq_task() and movie_record_task() are not done yet, so no overrides yet.
Pictures are not blurry.
Raw not tested yet.
