USB组合设备实现的结合鼠标和游戏手柄设备

资料介绍
his Technical Brief describes a USB combination
device consisting of a mouse and a gamepad imple-mented on a PIC16C765. Previous technical briefs
describe the translation of a PS/2

mouse to a USB
mouse (TB055) and the translation of a gameport
gamepad to a USB gamepad (TB054). These two
devices were combined to form the USB combination
device described in this brief. Details about the transla-tion and implementation of the mouse and the game-pad are not covered. Refer to the earlier briefs for this
information as well as their circuit diagrams. This brief
focuses on setting up the descriptors appropriately for
a combination device.
