[Plib-devel] X45 and X52 and buttons

[Jim C. <j.c...@zy...>]

Hi,
Without wishing to extend this thread too far - as well as the buttons 
on X52 problem (ie more than 32) there was also a problem with X45 not 
having its "dial" recognised so I added patch to jsMacOSX.cxx :
		if (page == kHIDPage_GenericDesktop) {		
			switch (usage) /* look at usage to determine function */
			{
				case kHIDUsage_GD_X:
				case kHIDUsage_GD_Y:
				case kHIDUsage_GD_Z:
				case kHIDUsage_GD_Rx:
				case kHIDUsage_GD_Ry:
				case kHIDUsage_GD_Rz:
				case kHIDUsage_GD_Slider: // for throttle / trim controls
            case kHIDUsage_GD_Dial:
					//printf(" axis\n");
					/*joy->os->*/addAxisElement(joy, (CFDictionaryRef) element);
					break;
					
				case kHIDUsage_GD_Hatswitch:
					//printf(" hat\n");
					/*joy->os->*/addHatElement(joy, (CFDictionaryRef) element);
					break;
					
				default:
					ulSetError(UL_WARNING, "input type element has weird usage 
(%lx)\n", usage);

whether this was the case on other platforms I dont know! It does show 
that more advanced joysticks have facilities that may have to be 
tailored!! - we may need to recognise GD_Wheel as well for instance.
The HIDusage tables on the Mac do give a pointer to the range of 
possibilities (including a special section for simulation) - see "HID 
Usage Tables" specification:
      http://www.usb.org/developers/hidpage/#Class_Definition
under "GenericDesktop" and "Simulation" pages.

cheers
