1、北通游戏手柄协议说明2011.11.16Iciyin纠结了好几天，手柄这个终于搞定了，难于usb协议。协议不会啊，所以选择了使用ch376芯片，很强大的一个芯片啊，支持读U盘，SD卡等我使用的模块是:STATUSP333U3SD.C8D7SD.加SD_DD5PCS3-IXRXCH376S20620512101RDDOML~3模块跟51单片机接好线示，打开串口调试助手就能查看返冋的数据。51跟CH376接线的接法：D0-D7P00-P07INTOP32CSP26AOP20WRP36RDP37游戏手柄是北通BTP-C0

2、24以下是我的分析：手柄采用USB协议，通信成功麻获取HID类设备的数据如下:UZuycoUUCOal02302UJ91UZ75ybuae150026OKLEIFANOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO53142531425314567788566778550000000000000000000000000000OOOOOOOOOOOOOO11OOOOOOOOOOOOOOub77777
