Hello,
I'm trying to create a hid report descriptor for a joystick with an X and Y axis and around 4 buttons. I've searched the web and I haven't been able to find any concise reading on how to build up a report descriptor. I've tried HID Tool under windows, but it seems really buggy and crashes frequently. Is there any alternative?
If anybody has a good tutorial/hidtool replacement/joystick + button report descriptor I'd really appreciate it.
thanks.

Re: hid report descriptor help
Here is a generic 8 button x,y hid. I never have a single bit of trouble with it.
Are you sure its the descriptor that is the trouble?
Code: Select all
const char generic_usbHidReportDescriptor[] PROGMEM = {
0x05, 0x01, // USAGE_PAGE (Generic Desktop)
0x09, 0x05, // USAGE (Game Pad)
0xa1, 0x01, // COLLECTION (Application)
0x09, 0x01, // USAGE (Pointer)
0xa1, 0x00, // COLLECTION (Physical)
0x09, 0x30, // USAGE (X)
0x09, 0x31, // USAGE (Y)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x26, 0xff, 0x00, // LOGICAL_MAXIMUM (255)
0x75, 0x08, // REPORT_SIZE (8)
0x95, 0x02, // REPORT_COUNT (2)
0x81, 0x02, // INPUT (Data,Var,Abs)
0xc0, // END_COLLECTION
0x05, 0x09, // USAGE_PAGE (Button)
0x19, 0x01, // USAGE_MINIMUM (Button 1)
0x29, 0x08, // USAGE_MAXIMUM (Button 8)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x25, 0x01, // LOGICAL_MAXIMUM (1)
0x75, 0x01, // REPORT_SIZE (1)
0x95, 0x08, // REPORT_COUNT (8)
0x81, 0x02, // INPUT (Data,Var,Abs)
0xc0
};Are you sure its the descriptor that is the trouble?
