带鼠标功能的键盘
- 一个接口实现
- - 报告描述符示例
- 多个接口实现
- - 复合设备和组合设备
  - 配置描述符集合的实现
  - 报告的返回
- 附 STM32 枚举日志

复合设备：Compound Device 内嵌 Hub 和多个 Function，每个 Function 都相当于一个独立的 USB 外设，有自己的 PID/VID/DID。
组合设备：Composite Device 内只有一个 Function，只有一套 PID/VID/DID。
这里使用组合设备来实现

带鼠标功能的键盘

要实现带鼠标功能的键盘有两种方式

一个接口，但是使用两个应用集合和两个报告
两个接口，分别实现键盘和鼠标

一个接口实现

设备描述符，配置描述符，HID 描述符 (注意报告描述符的长度) 和端点描述符等保持不变，唯一不同的是报告描述符和报告描述符的长度。

报告描述符示例

端点 0 最大包长为 64，分包传输如下

0x5 0x1 0x9 0x6 0xa1 0x1 0x85 0x1 0x5 0x7 0x19 0xe0 0x29 0xe7 0x15 0x0 0x25 0x1 0x95 0x8 0x75 0x1 0x81 0x2 0x95 0x1 0x75 0x8 0x81 0x1 0x5 0x8 0x19 0x1 0x29 0x5 0x95 0x5 0x75 0x1 0x91 0x2 0x95 0x1 0x75 0x3 0x91 0x1 0x5 0x7 0x19 0x0 0x2a 0xff 0x0 0x15 0x0 0x26 0xff 0x0 0x95 0x6 0x75 0x8

0x81 0x0 0xc0 0x5 0x1 0x9 0x2 0xa1 0x1 0x85 0x2 0x9 0x1 0xa1 0x0 0x5 0x9 0x19 0x1 0x29 0x5 0x15 0x0 0x25 0x1 0x95 0x5 0x75 0x1 0x81 0x2 0x95 0x1 0x75 0x3 0x81 0x1 0x5 0x1 0x9 0x30 0x9 0x31 0x15 0x81 0x25 0x7f 0x95 0x2 0x75 0x8 0x81 0x6 0x9 0x38 0x15 0x81 0x25 0x7f 0x95 0x1 0x75 0x8 0x81

:0x6 0x5 0xc 0xa 0x38 0x2 0x15 0x81 0x25 0x7f 0x95 0x1 0x75 0x8 0x81 0x6 0xc0 0xc0 0x5 0xc 0x9 0x1 0xa1 0x1 0x85 0x3 0x15 0x0 0x26 0xff 0x3 0x19 0x0 0x2a 0xff 0x3 0x95 0x1 0x75 0x10 0x81 0x0 0xc0 0x5 0x1 0x9 0x5 0xa1 0x1 0x85 0x4 0x5 0x1 0x9 0x30 0x9 0x31 0x9 0x32 0x9 0x35 0x9 0x33 0x9

0x34 0x15 0x81 0x25 0x7f 0x95 0x6 0x75 0x8 0x81 0x2 0x5 0x1 0x9 0x39 0x15 0x1 0x25 0x8 0x35 0x0 0x46 0x3b 0x1 0x95 0x1 0x75 0x8 0x81 0x2 0x5 0x9 0x19 0x1 0x29 0x20 0x15 0x0 0x25 0x1 0x95 0x20 0x75 0x1 0x81 0x2 0xc0

上述报告描述符设置了四个报告

KEYBOARD：ID 为 1
MOUSE：ID 为 2
CONSUMER_CONTROL：ID 为 3
GAMEPAD：ID 为 4

报告返回时，报告的最低为 a 指定报告 ID 即可
例如键盘报告的返回, 最低为 1

0x1 0x0 0x0 0x4 0x0 0x0 0x0 0x0 0x0

0x01 表示键盘的报告
0x04 表示 a 按下

鼠标报告的返回最低为为 2

0x2 0x0 0x5 0x5 0x0 0x0

0x02 表示鼠标的报告
0x05 表示 x 轴移动量
0x05 表示 y 轴移动量

其他报告的返回类似。

多个接口实现

复合设备和组合设备

USB - 描述符之间的关系中可以知道，多个接口实现时，一个接口实现鼠标，一个接口实现键盘，所以此时的配置描述符集合为

{配置描述符，接口 1 描述符接口描述符 (键盘接口)，类特殊描述符 (HID 描述符 - 键盘)，端点描述符 (键盘输入端点)，接口 2 描述符接口描述符 (鼠标接口)，类特殊描述符 (HID 描述符 - 鼠标)，端点描述符 (鼠标输入端点)，
}

配置描述符集合的实现

0x9 0x2 0x3b 0x0 0x2 0x1 0x0 0xa0 0x32 0x9 0x4 0x0 0x0 0x1 0x3 0x1 0x1 0x4 0x9 0x21 0x11 0x1 0x0 0x1 0x22 0x41 0x0 0x7 0x5 0x81 0x3 0x8 0x0 0xa 0x9 0x4 0x1 0x0 0x1 0x3 0x1 0x2 0x5 0x9 0x21 0x11 0x1 0x0 0x1 0x22 0x4d 0x0 0x7 0x5 0x82 0x3 0x8 0x0 0xa

配置描述符 (0x9 0x2 0x3b 0x0 0x2 0x1 0x0 0xa0 0x32)
键盘接口描述符
- 接口描述符 (0x9 0x4 0x0 0x0 0x1 0x3 0x1 0x1 0x4)
- 类特殊描述符 (HID 描述符：0x9 0x21 0x11 0x1 0x0 0x1 0x22 0x41 0x0)
- 端点描述符 (0x7 0x5 0x81 0x3 0x8 0x0 0xa)
鼠标接口描述符
- 接口描述符 (0x9 0x4 0x1 0x0 0x1 0x3 0x1 0x2 0x5)
- 类特殊描述符 (HID 描述符：0x9 0x21 0x11 0x1 0x0 0x1 0x22 0x4d 0x0)
- 端点描述符 (0x7 0x5 0x82 0x3 0x8 0x0 0xa)

配置描述符的 bNumInterfaces(第五个数据) 的值为 2，表明有两个接口
接口描述符的 bInterfaceNumber(第三个数据) 表示接口的编号，从 0 开始。
接口描述符的 iInterface(最后一个数据) 表示接口字符串的索引，主机在获取字符串描述符时，需要根据索引返回相应的字符串。

报告的返回

0x0 0x0 0x4 0x0 0x0 0x0 0x0 0x0
0x0 0x5 0x5 0x0 0x0

往对应的端点写数据即可。
