USB-HID鼠标、键盘通讯格式

原帖地址：http://www.amobbs.com/forum.php?mod=viewthread&tid=4823160&page=1&authorid=249202

想用STM32做个无线键鼠遥控、找了好几天没有找到完整的USB鼠标键盘协议介绍。最后自己收集整理了一份，希望对需要的朋友有所帮助。
废话不多说，进入正题：

鼠标发送给PC的数据每次4个字节
BYTE1 BYTE2 BYTE3 BYTE4
定义分别是：
BYTE1 —
|–bit7: 1 表示 Y 坐标的变化量超出－256 ~ 255的范围,0表示没有溢出
|–bit6: 1 表示 X 坐标的变化量超出－256 ~ 255的范围，0表示没有溢出
|–bit5: Y 坐标变化的符号位，1表示负数，即鼠标向下移动
|–bit4: X 坐标变化的符号位，1表示负数，即鼠标向左移动
|–bit3:    恒为1
|–bit2:    1表示中键按下
|–bit1:    1表示右键按下
|–bit0:    1表示左键按下
BYTE2 — X坐标变化量，与byte的bit4组成9位符号数,负数表示向左移，正数表右移。用补码表示变化量
BYTE3 — Y坐标变化量，与byte的bit5组成9位符号数，负数表示向下移，正数表上移。用补码表示变化量
BYTE4 — 滚轮变化。
由于手上没有USB鼠标，对BYTE1的4-7位没有测试，对于BYTE2 BYTE3做个测试，BYTE1的4-7全为0的时候，BYTE2 BYTE3的正负表示鼠标移动方向

键盘发送给PC的数据每次8个字节
BYTE1 BYTE2 BYTE3 BYTE4 BYTE5 BYTE6 BYTE7 BYTE8
定义分别是：
BYTE1 —
|–bit0: Left Control是否按下，按下为1
|–bit1: Left Shift 是否按下，按下为1
|–bit2: Left Alt 是否按下，按下为1
|–bit3: Left GUI 是否按下，按下为1
|–bit4: Right Control是否按下，按下为1
|–bit5: Right Shift 是否按下，按下为1
|–bit6: Right Alt 是否按下，按下为1
|–bit7: Right GUI 是否按下，按下为1
BYTE2 — 暂不清楚，有的地方说是保留位
BYTE3–BYTE8 — 这六个为普通按键
键盘经过测试。
例如：键盘发送一帧数据 02 00 0x04 0x05 00 00 00 00
表示同时按下了Left Shift + ‘a’+’b’三个键
对于键码和PS2的键盘有所不同，具体请看附件。

2011.6.23补充说明
补充对于键盘BYTE2的说明：
参照百合网（http://www.baiheee.com/OpenSource/Easy%20USB%2051%20Programer/Easy%20USB%2051%20Programer12.htm）键盘的报告描述符，如下
/*******************************************************************************************/
//这里只列出了第二个字节的说明
//这样的数据段个数为1
0x95, 0x01,                   // REPORT_COUNT (1)
//每个段长度为8bits
0x75, 0x08,                   // REPORT_SIZE (8)
//输入用，常量，值，绝对值
0x81, 0x03,                   // INPUT (Cnst,Var,Abs)

//上面这8个bit是常量，设备必须返回0
/*******************************************************************************************/
这里只是指明了这是一个以字节为单位的输入数据，并没有指明它的取值范围。

在HID1.11协议的Appendix B–>B.1 Protocol 1 (Keyboard) 的报告描述符中也有这样的说明（HID1.11协议的59页）
/*******************************************************************************************/
Report Count (1),
Report Size (8),
Input (Constant), ;Reserved byte
Report Count (5),
Report Size (1),
/*******************************************************************************************/
在注释中说明，这个字节是保留字节。
这里我也把HID1.11传上来给大家研究。
