【请问 ch374 设置NUMlock指示灯问题】

这个是HID类协议。你可以看下HID类协议。


把你配置描述符的值和SET-REPORT发的数组SetupSetReport里的值全部发上来看看


unsigned char SetupSetReport[]={0x21,0x09,0x00,0x02,0x00,0x00,0x01,0x00};


配置描述符的值呢?


const UINT8C SetupGetDevDescr[] = { 0x80, 0x06, 0x00, 0x01, 0x00, 0x00, 0x12, 0x00 }; /* 获取配置描述符 */ const UINT8C SetupGetCfgDescr[] = { 0x80, 0x06, 0x00, 0x02, 0x00, 0x00, 0x04, 0x00 }; /* 设置USB地址 */ const UINT8C SetupSetUsbAddr[] = { 0x00, 0x05, 0x02, 0x00, 0x00, 0x00, 0x00, 0x00 }; /* 设置USB配置 */ const UINT8C SetupSetUsbConfig[] = { 0x00, 0x09, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 }; /* SET IDLE */ unsigned char SetupSetidle[]={0x21,0x0a,0x00,0x00,0x00,0x00,0x00,0x00}; /* 获取HID 报告描述符 */ unsigned char SetupGetHidDes[]={0x81,0x06,0x00,0x22,0x00,0x00,0x81,0x00}; /* SET REPORT */ unsigned char SetupSetReport[]={0x21,0x09,0x00,0x02,0x00,0x00,0x01,0x00};
