Initial version of this page

This is a first try for a "build your own CHDK" tutorial. I hope I did not make too many mistakes, since I don't really know much about C. Please feel free to correct or add things as you like.
I'd like to have written some words about the files in the 'core' folder, but I don't know enough of it. Most file names are self-explanatory (gui_batt, gui_calendar etc.), but some I do not understand at first (gui_fselect, gui_mbox, nothumb, Makefile). --Harvester 12:13, 21 May 2007 (UTC)

A build question - I've built on Windows successfully on one laptop, but on another laptop when I try to build in the cmd shell I see:

  • Error from getconsolebufinfo Oyi
  • Error from setcursor Oyi

When I press enter, I see the messages again. The shell is hung. The 'Oyi' characters change. Anyone seen this?

Later... I've made some progress. The problem seems to be due to the 'gmake.exe' in the build environment. When I rename it to 'gmakefoo.exe' and build using 'gmakefoo fir' it works. Under cygwin too, not just dos. Not sure what's up. --Mike McCabe

USB access?

Can scripts written for chdk access the camera's USB port? If yes, I'd like to build a GPS peripheral for automatic geotagging.

  • No, at the moment CHDK can only recognize the USB power signal, this is used for the USB remote control feature. Fe50 21:40, 1 July 2008 (UTC)
