USB键盘数据格式以及按键键值

USB键盘数据包含8个字节

BYTE1 – 特殊按键

|–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（Windows键） 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 – 好像必须为0，反正0没错

BYTE3-BYTE8 当前按下的普通按键键值，也就是最多六个按键

上面这些东西很容易查到，而且能查到很详细的，但是具体按键的键值在网上查了查，没看到。最后在USB HID USAGE TABLE文件里面找到了，分享出来。
