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.)

================================================================= Patch version 0.8 of SDL(Simple DirectMedia Layer) for Nano-X API ================================================================= Author: Hsieh-Fu Tsai, clare@setabox.com There are two patch files in this package. 1. The first patch file, nanox.patch, is to fix a bug in Nano-X. This patch is proposed by Gary James (gjames@twcny.rr.com). It fixes the client side GrClose(). In the original version, GrOpen() can only be called once. When the GrOpen() is called at the second time, the program will terminate. In order to prevent this situation, we need to insert "nxSocket = -1" after "close(nxSocket)" in GrClose(). If you do not have this problem, you may skip this step. ============= Quick Install ============= 1. ./configure --disable-video-x11 --disable-video-fbcon \ --enable-video-nanox \ --with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal] 2. make clean 3. make 4. make install (as root) ============ Nitty-gritty ============ --with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal] If the wrong pixel type is used, the program will crash when the sub-routine updates the screen. This option depends on SCREEN_PIXTYPE which is defined in Microwin0.89pre7/src/config. SCREEN_PIXTYPE is used to define the pixel type in Microwindows/Nano-X. I only test the program when the pixel type is in "rgb" (Microwin under X11) or "888" (framebuffer in 24-bit). --enable-nanox-debug Show debug messages --enable-nanox-share-memory Use shared-memory to speed up ============================================= Some programs can be used to test this patch. ============================================= 1. http://www.cs.berkeley.edu/~weimer/atris (a tetris-like game) 2. http://www.libsdl.org/projects/newvox/ 3. http://www.libsdl.org/projects/xflame/ 4. http://www.libsdl.org/projects/optimum/ 5. http://www.gnugeneration.com/software/loop/ ========= Todo List ========= 1. Create hardware surface 2. Create YUVOverlay on hardware 3. Use OpenGL 4. Gamma correction 5. Hide/Change mouse pointer ===================== Supporting Institutes ===================== Many thanks to go to Setabox Co., Ltd. and CML (Communication and Multimedia Laboratory, http://www.cmlab.csie.ntu.edu.tw/) in the Department of Computer Science and Information Engineering of National Taiwan University for supporting this porting project. =================== Contact Information =================== Welcome to give me any suggestion and to report bugs.
