    Hello & welcome, BlueMagic !
    Using the manual CHDK load in play mode through the firmware update function, the CHDK splash screen comes up...
    Do you have any ideas what's wrong here?
    Nothing is wrong there, the only thing you should do is ... reading the manual: Firmware usage    ;)

    • To enter the CHDK <Alt> mode, press the PRINT button
    • To enter the CHDK main menu, press MENU while you're in <Alt> mode
    • After you've set up your CHDK settings, leave the <Alt> mode by pressing PRINT again

    Ha! That is good news! Thank you!
    I got it to work.
    Must've missed those instructions in the install guide.
    I will download and read the manual now to start exploring the CHDK.

    Thanks to anyone contributing to CHDK and this port! :)

    Hello & welcome, tkgafs !
    my question is can the camera be powered from the usb socket ?
    No, this is not possible, USB is only used for data connection.

    Thanks for the information

    I'll look into building my own power supply in that case

    Can the SX200 be triggered using a home made USB remote ?

    thanks again

    Yes, USB remote is available in all CHDK versions: --> CHDK wikia: USB remote

    With a small microcontroller (e.g. a Picaxe chip like the 08M, easily programmable with a nice BASIC language) it is also possible to do several actions like zoom in/out...

    Very good job for this porting, i have tried it and it work fine.

    Not sure, I am having the same problem on my SD980. You might want to use the DNG format.

    I have tried this but when i select the DNG format, i have the error message "Cannot load CHDK/badpixel.bin please run CHDK/SCRIPTS/TEST/badpixel.lua"
    Maybe this part is not ported yet ?

    Code: (c) [Select]
    //in camera.h (example alternative configurations)


    #define ASPECT_XCORRECTION(x)  ( ( (((x) *3)>>1) ) ) //for screen 480x240

    //and for grids

    #define ASPECT_GRID_XCORRECTION(x)  ( ((x)<<2)/3  )  //for screen 480x240

    //and in lib.c (for 480x240 for example)

    long vid_get_bitmap_screen_width()
    {
            //here will be good the SCREENX, SCREENY macros to change only one file (camera.h)
    return 480;
    }

    long vid_get_bitmap_screen_height()
    {
    return 240;
    }


    That are the best code for me to see the Menu in full screenwidth.

    The Letters in the Menu good readable.
