Subject: [SDL] src/joystick/bsd/SDL_sysjoystick.c patch
The *BSD USB HID joystick code has two serious bugs:
1. If a joystick reports unhandled hid_input usage (for example HUG_RZ or
HUG_DIAL), then the last handled value will be overwritten with an
arbitrary value. (Fixed in the patch below by adding a default case.)
2. The current code does only handle logical coordinates in the range 0-255,
while a big part of available joysticks report -128 - 127. (This is solved
in the patch below by first center the range around 0, and then stretch
it to the correct range.)

============================================================================== Using the Simple DirectMedia Layer with EPOC/SymbianOS 6.0 ============================================================================== ============================================================================== I. Building the Simple DirectMedia Layer libraries: You can get Symbian SDK from: http://www.symbian.com. First create "Epoc" directory under SDL main directory and unpack EpocBuildFiles.zip in it. To build the librarys goto "epoc" directory and type: bldmake bldfiles abld makefile vc6 (for creating Microsoft Visual C++ makefiles) abld build wins udeb (building for wins emulator) abld build armi urel (building for real device) ============================================================================== II. Building the Simple DirectMedia Layer programs: Building SDL test programs is easy once you have built the libraries: abld test build wins udeb abld test build armi urel Supported real screen resolutions 320 x 200 x 8 bit 320 x 200 x 12 bit 640 x 200 x 8 bit 640 x 200 x 12 bit Supported "emulated" screen resolutions 640 x 400 x 8 bit 640 x 400 x 12 bit 640 x 480 x 8 bit 640 x 480 x 12 bit "Emulated" resolutions are implemented by by shrinking the screen vertically i.e. only every second scanline is drawn. This is mainly ment to be used for testing quick ports of programs. Using faked resolutions is a waste of memory and cpu power! ============================================================================== III. Running test programs Copy executable to the device and run it from the File manager. The Esc key quits demo programs. In Crystal, Exe programs do not appear in task list nor in Extras :-(. Test programs are tested in Nokia 9210 Communicator. Special keys used in SDL: The Caps lock key enables or disables the virtual cursor. Function keys are mapped as follows: F1=chr+q, F2=chr+w,..., F8=chr+i, F9=chr+a,..., F12=chr+d. ============================================================================== IV. Enjoy! :) If you have a project you'd like me to know about, or want to ask questions, go ahead and join the SDL developer's mailing list by sending e-mail to: sdl-request@libsdl.org and put "subscribe" into the subject of the message. Or alternatively you can use the web interface: http://www.libsdl.org/mailman/listinfo/sdl You can find more info about Epoc version of SDL from Hannu Viitala's homepage http://www.mbnet.fi/~haviital ==============================================================================
