HOW TO INTERFACE GAME CONTROL OF XP USING KEIL MCB2140 HID EXAMPLE WITHOUT RTOS

I WANT TO INTERFACE MY KIT WITH TWO SWITCHES AND 2 VARIABLE RESISTANCE TO TO DISPLAY DATA ON X AN Y AXIS OF GAME CONTROL AND SWITCH TO ENABLE DIGITAL INPUT 1 AND 2 RESPECTIVELY.

Tsuneo Chinzei
I HAD LEARNED YOUR GENERIC PROGRAM TO SEND THE ARRAY FOR INPUT AND OUTPUT REPORT AND IMPLIMENT IT AND CHANGE THE CONFIGURATION TO GET GRAPHICAL INTERFACE ALSO BUT i DONT UNDERSTAND THE REPORT SECTION AND THEIR PROPER USE HOW TO CHANGE IT ACCORDING TO OUR REQUIREMENT.

EAGERLY WAITING FOR ANY HELP
