    Patch for IXUS120-SD940 (all firmware versions)

    This patch corrects a major bug in capt_seq.c for all firmware versions.  The bug had been partially masked by commenting out one of the calls to the CHDK hooks.  This resulted in impaired USB_Remote functionality and possible crashes in some shooting modes.

    This patch enables USB remote operation in "Synchable Remote" mode.  In this mode the camera does a "half shoot" on application of 5V on the USB port and a "full shoot" when the 5V is removed.
    Added changeset  1334

    Attached is a cosmetic patch regarding A410. It removes the "global" declaration and use of MoveFocusLensToDistanceA410() as it seems to be unneeded. It's now only a local function for the port.
    Added, changeset 1335

    Oh, btw. Is there something wrong with this patch for the SX100? If it gets accepted, I could do the same for the other firmware revision (the change should be trivial, but I will not be able to test that of course). Here is my previous post.
    I'm not clear if this is tested ?   If it is then it should be fine Looks like you do have that camera. On some cameras the second "taskhook" is only needed for some tasks, but in your case there is only one task started this way.

    The way our ifdefs are set up, it is hard to have features like extra long exposure enabled for only one sub so you'd need to do both before we can put it in the trunk.

    Don't forget what the H stands for.

    Yes, I have tested it on my 1.00c camera.

    Looking at some (earlier) discussions and also at some DryOS ports, it's still not clear to me, how this mechanism works. When I removed the modification of the 0x1934 location, the modified exp_drv_task() still managed to start. I have only tested this twice: first time with the camera started in playback mode, second time with the camera started with a long press on the on/off button. Both tests were succesful.
    But, since most ports use two taskhook locations (with the override for exp_drv_task included in both), I decided to follow that practice.

    Yeah, I forgot about that. So here's the patch for both fw revisions, also included the fix for the vanishing menus.

    Hi, I ported the firmware version 100f to 100d, for the powershot a490, with the help of CHDK-PT.

    Everything seems to be working fine...

    I have attached a patch-file for the trunk. I think everything should be included. Could someone add this to the repository?

    The patch in previous post is against trunk revision 1344

    The patch is missing the 'capt_seq.c' file.

    I would also recommend verifying all the addresses that are reported as possibly incorrect in stubs_entry.S and correct if necessary (e.g. the levent_table and FlashParamsTable addresses in stubs_min.S).

    Here's a patch file to add get_config_value() and set_config_value() to Lua and uBASIC.  Its taken directly from CHDK-DE.

    This is in response to this request http://chdk.setepontos.com/index.php?topic=6429.msg73673#msg73673

    It actually seems like a good idea but reyalp may have some history as to why this was not added in the past.

    If its accepted,  I'll update the wiki as best I can.

    A patch to add four really simple scripts (Lua and uBasic versions so 8 files total) to the install files. These scripts implement the most common functions people want from CHDK (shoot with delay, intervalometer, motion detect, HDR).   Lots of room for people to experiment and improve.  What I was looking for was the most basic way to do the core CHDK scripted functions - curiously those are not included in the standard CHDK build.

    The scripts are written to be generic -  nothing specific to a particular camera model.

    Hi Phil,

    Here is the patch with capt_seq included. Sorry for that. I don't know how to check/correct the addresses in stubs_entry.S, but so far, things seem to be working.
    If someone can explain how to correct the addresses, assuming little foreknowledge, I can do that, but I have little time the next two weeks...
