#STM32 USB HID复合设备 两个接口 键盘+数据传输 功能
本人想要做一个USB设备，它能够模拟键盘给PC发数据，并且也能够和PC进行数据通信，这里键盘只做了发送功能，并不能接受PC端的大小写切换从而改变键盘灯的颜色。
具体逻辑如下：
这里的做法是，USB为复合设备，有两个接口，一个接口为：传输数据的自定义接口（两个端点，双向传输），另一个接口为：键盘（一个端点，只能键盘给PC发）
先使用STM32CUBEMX生成一个模板工程，并且将其修改为HID传输数据。

1、首先打开USB
2、接着把USB设置为下图HID模式
3、选择外部时钟
4、配置时钟树
5、配置USB设置
下面的USB设置就有点讲究了，
6、确认后，生成代码
打开刚才建立的工程，在 usbd_custom_hid_if.c 文件里，找到 CUSTOM_HID_ReportDesc_FS 这个函数，把刚才生成的报文文件覆盖掉函数里面的文件，代码如下：
/** Usb HID report descriptor. */
__ALIGN_BEGIN static uint8_t CUSTOM_HID_ReportDesc_FS[USBD_CUSTOM_HID_REPORT_DESC_SIZE] __ALIGN_END =
{
0x06, 0x00, 0xff, // USAGE_PAGE (Vendor Defined Page 1)
0x09, 0x01, // USAGE (Vendor Usage 1)
0xa1, 0x01, // COLLECTION (Application)
0x09, 0x01, // USAGE (Vendor Usage 1)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x26, 0xff, 0x00, // LOGICAL_MAXIMUM (255)
0x95, 0x40, // REPORT_COUNT (64)
0x75, 0x08, // REPORT_SIZE (8)
0x81, 0x02, // INPUT (Data,Var,Abs)
0x09, 0x01, // USAGE (Vendor Usage 1)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x26, 0xff, 0x00, // LOGICAL_MAXIMUM (255)
0x95, 0x40, // REPORT_COUNT (64)
0x75, 0x08, // REPORT_SIZE (8)
0x91, 0x02, // OUTPUT (Data,Var,Abs)
0xc0 // END_COLLECTION
};然后再修改将usbd_conf.h做对应修改：
#define USBD_CUSTOMHID_OUTREPORT_BUF_SIZE 64
#define USBD_CUSTOM_HID_REPORT_DESC_SIZE 34同时修改usbd_customhid.h文件中的发送与接收长度为64
#define CUSTOM_HID_EPIN_SIZE 0x40
#define CUSTOM_HID_EPOUT_SIZE 0x40到这里基本就算做出一个USB设备了，我们编译下载程序看看。
如果电脑显示了这个USB设备，但是有黄色感叹号，说明USB枚举成功，可是驱动安装失败，这时我们可以libusb自带的inf-wizard工具生成USB驱动程序，要怎么安装驱动解决这个问题可以参考驱动安装：https://blog.csdn.net/niepangu/article/details/44984325，驱动安装成功的话，到这里我们就可以看到USB正常列举出来啦，下面我们就可以写USB数据收发代码了。
USB数据传输：参考http://www.stm32cube.com/article/138
关于数据传输，HID设备是采用轮询方式传输的，ST默认20ms速度实在不敢恭维，还得要改一下枚举时的声明，同样是usbd_customhid.c文件，
__ALIGN_BEGIN static uint8_t USBD_CUSTOM_HID_CfgDesc[USB_CUSTOM_HID_CONFIG_DESC_SIZ] __ALIGN_END =
{
....
....
0x20, /*bInterval: Polling Interval (20 ms)*/
/* 34 */
....
....
0x20,/* bInterval: Polling Interval (20 ms) */
/* 41 */
}这两个地方随心来改，最小可以改到0x01。这就快很多啦。（这里可以不做修改，我的电脑上生成的是5ms）到这里数据传输准备工作就做好了，下面我们先来说一下USB发送:
先定义个发送BUFF：
uint8_t send_buf[64] = {//定义一个USB的发送BUFF
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,
17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,
40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64};再包括发送函数头文件以及声明一个外部定义（main.c文件中）：
#include "usbd_customhid.h" //包括发送函数头文件
extern USBD_HandleTypeDef hUsbDeviceFS; //外部声明USB发送函数现在可以在main函数里添加发送代码了，我这里设置按一下按键就发送一次，同时led亮1s：
while (1)
{
/* USER CODE BEGIN 3 */
if(HAL_GPIO_ReadPin(GPIOE,k1_Pin)==0)
{
//按键消抖
while(HAL_GPIO_ReadPin(GPIOE,k1_Pin)==0);
//点亮指示灯
HAL_GPIO_WritePin(GPIOE,led1_Pin,GPIO_PIN_RESET);
//USB发送数据
USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, send_buf, sizeof(send_buf));
//实际发送到上位机的数据有65个，一个报文ID：0 + 64个send_buf 数据，一共65个数据到上位机
HAL_Delay(1000);
//关闭指示灯
HAL_GPIO_WritePin(GPIOE,led1_Pin,GPIO_PIN_SET);
}
}发送函数就是这么简单，接下来说接收函数了，接收函数是中断接收的，建立工程时已经默认开启了。下面就说一下USB接收：
先在main.c定义个接收BUFF：
unsigned char USB_Recive_Buffer[64]; //USB接收缓存
unsigned char USB_Received_Count = 0;//USB接收数据计数打开usbd_custom_hid_if.c文件，添加外部声明：
extern unsigned char USB_Recive_Buffer[64];
extern unsigned char USB_Received_Count;接着在usbd_custom_hid_if.c文件中找到 static int8_t CUSTOM_HID_OutEvent_FS(uint8_t event_idx, uint8_t state) 函数，当USB接收完数据后，就会进入到这个函数，我们可以在这里添加接收函数，把函数修改如下：
/**
* @brief Manage the CUSTOM HID class events
* @param event_idx: Event index
* @param state: Event state
* @retval USBD_OK if all operations are OK else USBD_FAIL
*/
//当芯片完成一组数据接收的时候，中断会调用CUSTOM_HID_OutEvent_FS这个回调函数
static int8_t CUSTOM_HID_OutEvent_FS(uint8_t event_idx, uint8_t state)
{
/* USER CODE BEGIN 6 */
char i;
HAL_GPIO_TogglePin(GPIOE,led1_Pin);
/*查看接收数据长度
USB_Received_Count = USBD_GetRxCount( &hUsbDeviceFS,CUSTOM_HID_EPOUT_ADDR );
printf("USB_Received_Count = %d \r\n",USB_Received_Count);
USB_Received_Count = USBD_GetRxCount( &hUsbDeviceFS,CUSTOM_HID_EPIN_ADDR );
printf("USB_Received_Count_in = %d \r\n",USB_Received_Count);
*/
USBD_CUSTOM_HID_HandleTypeDef *hhid; //定义一个指向USBD_CUSTOM_HID_HandleTypeDef结构体的指针
hhid = (USBD_CUSTOM_HID_HandleTypeDef*)hUsbDeviceFS.pClassData;//得到USB接收数据的储存地址
for(i=0;i<64;i++)
{
USB_Recive_Buffer[i]=hhid->Report_buf[i]; //把接收到的数据送到自定义的缓存区保存（Report_buf[i]为USB的接收缓存区）
//printf("USB_Recive_Buffer[%d] = 0x%x \r\n",i,USB_Recive_Buffer[i]); //打印接收到的信息，确认是否正确，调试用
}
return USBD_OK;
/* USER CODE END 6 */
}这样就 USB_Recive_Buffer[i] 里面就保存到接收到的数据了，用Bus Hound可以看到已经成功啦。
这里我使用的不是Bus Hound，而是这个软件，个人感觉用起来更顺手（需要的可以加我企鹅：1205775165）
以上实现了数据传输，接下来只需要再添加一个键盘的interface就行，后续步骤参考了如下
参考1
参考2
在usbd_customhid.c文件中找到如下定义
/* USB CUSTOM_HID device FS Configuration Descriptor */
__ALIGN_BEGIN static uint8_t USBD_CUSTOM_HID_CfgFSDesc[USB_CUSTOM_HID_CONFIG_DESC_SIZ] __ALIGN_END =
{
0x09, /* bLength: Configuration Descriptor size */
USB_DESC_TYPE_CONFIGURATION, /* bDescriptorType: Configuration */
USB_CUSTOM_HID_CONFIG_DESC_SIZ,
/* wTotalLength: Bytes returned */
0x00,
0x01, /*bNumInterfaces: 1 interface*/
0x01, /*bConfigurationValue: Configuration value*/
0x00, /*iConfiguration: Index of string descriptor describing
the configuration*/
0xC0, /*bmAttributes: bus powered */
0x32, /*MaxPower 100 mA: this current is used for detecting Vbus*/
........................
........................ 省略
........................
0x03, /* bmAttributes: Interrupt endpoint */
CUSTOM_HID_EPOUT_SIZE, /* wMaxPacketSize: 2 Bytes max */
0x00,
CUSTOM_HID_FS_BINTERVAL, /* bInterval: Polling Interval */
/* 41 */
};
这部分就是配置描述符， 我们把这部分其中的
0x01, /*bNumInterfaces: 1 interface*/修改为
0x02, /*bNumInterfaces: 1 interface*/表示有两个接口
并在最后添加如下代码：
/************** Descriptor of Joystick Keyboard interface ****************/
0x09, /*bLength: Interface Descriptor size*/
USB_DESC_TYPE_INTERFACE,/*bDescriptorType: Interface descriptor type*/
0x01, /*bInterfaceNumber: Number of Interface*/
0x00, /*bAlternateSetting: Alternate setting*/
0x01, /*bNumEndpoints*/
0x03, /*bInterfaceClass: HID*/
0x01, /*bInterfaceSubClass : 1=BOOT, 0=no boot*/
0x01, /*nInterfaceProtocol : 0=none, 1=keyboard, 2=mouse*/
0, /*iInterface: Index of string descriptor*/
/******************** Descriptor of Joystick Keyboard HID ********************/
/* 50 */
0x09, /*bLength: HID Descriptor size*/
CUSTOM_HID_DESCRIPTOR_TYPE, /*bDescriptorType: HID*/
0x11, /*bcdHID: HID Class Spec release number*/
0x01,
0x00, /*bCountryCode: Hardware target country*/
0x01, /*bNumDescriptors: Number of HID class descriptors to follow*/
0x22, /*bDescriptorType*/
HID_KEYBOARD_REPORT_DESC_SIZE,/*wItemLength: Total length of Report descriptor*/
0x00,
/******************** Descriptor of Keyboard endpoint ********************/
/* 59 */
0x07, /*bLength: Endpoint Descriptor size*/
USB_DESC_TYPE_ENDPOINT, /*bDescriptorType:*/
HID_EPIN_ADDR, /*bEndpointAddress: Endpoint Address (IN)*/
0x03, /*bmAttributes: Interrupt endpoint*/
HID_EPIN_SIZE, /*wMaxPacketSize: 8 Byte max */
0x00,
CUSTOM_HID_FS_BINTERVAL, /*bInterval: Polling Interval (10 ms)*/
/* 66 */这里的/* 数字 */ 是用来记录当前数组有多大的。可以看到原来这个数组大小为USB_CUSTOM_HID_CONFIG_DESC_SIZ，
我们右键go to definition过去可以看到是
#define USB_CUSTOM_HID_CONFIG_DESC_SIZ 41U现在在结尾添加了一个接口的信息，总大小已经是66了，所以我们修改为66
#define USB_CUSTOM_HID_CONFIG_DESC_SIZ 66U添加后可以看到，有些宏定义是没有的，我们到usbd_conf.h文件夹中添加如下：
#define HID_KEYBOARD_REPORT_DESC_SIZE 63在usbd_custom.h中添加如下：
#define HID_EPIN_ADDR 0x82U
#define HID_EPIN_SIZE 0x08U我们增加了一个0X82这个端点，所以我们需要在初始化函数中添加对其的初始化。打开usbd_customhid.c文件，可以找到一个
static uint8_t USBD_CUSTOM_HID_Init(USBD_HandleTypeDef *pdev,uint8_t cfgidx)的函数， 我们在其中添加如下代码：
USBD_LL_OpenEP(pdev, HID_EPIN_ADDR, USBD_EP_TYPE_INTR, //KEYBOARD
HID_EPIN_SIZE); 我们在usbd_customhid.c文件中（尽量定义在文件的上方一点，最好在所有函数之前），添加一个键盘的报表
__ALIGN_BEGIN static uint8_t HID_KEYBOARD_ReportDesc[HID_KEYBOARD_REPORT_DESC_SIZE] __ALIGN_END ={
0x05, 0x01,// USAGE_PAGE (Generic Desktop)
0x09, 0x06,// USAGE (Keyboard)

0x15, 0x00,// LOGICAL_MINIMUM (0)

0x75, 0x03,// REPORT_SIZE (3)
0x91, 0x03,// OUTPUT (Cnst,Var,Abs)
0x95, 0x06,// REPORT_COUNT (6)
0x75, 0x08,// REPORT_SIZE (8)
0x15, 0x00,// LOGICAL_MINIMUM (0)
0x25, 0xFF,// LOGICAL_MAXIMUM (255)
0x05, 0x07,// USAGE_PAGE (Keyboard)
0x19, 0x00,// USAGE_MINIMUM (Reserved (no event indicated))
0x29, 0x65,// USAGE_MAXIMUM (Keyboard Application)
0x81, 0x00,// INPUT (Data,Ary,Abs)
0xc0
}还是在usbd_customhid.c文件中我们可以找到
static uint8_t USBD_CUSTOM_HID_Setup(USBD_HandleTypeDef *pdev,USBD_SetupReqTypedef *req)函数
在case USB_REQ_TYPE_STANDARD:下的case USB_REQ_GET_DESCRIPTOR:下 有如下代码
case USB_REQ_GET_DESCRIPTOR:
if (req->wValue >> 8 == CUSTOM_HID_REPORT_DESC)
{
len = MIN(USBD_CUSTOM_HID_REPORT_DESC_SIZE, req->wLength);
pbuf = ((USBD_CUSTOM_HID_ItfTypeDef *)pdev->pUserData)->pReport;
}
else
{
if (req->wValue >> 8 == CUSTOM_HID_DESCRIPTOR_TYPE)
{
pbuf = USBD_CUSTOM_HID_Desc;
len = MIN(USB_CUSTOM_HID_DESC_SIZ, req->wLength);
}
}把其中第一个if里面的东西修改为：
if(req->wIndex == 0){ // 如果是接口0 还是用以前的报表
len = MIN(USBD_CUSTOM_HID_REPORT_DESC_SIZE, req->wLength);
pbuf = ((USBD_CUSTOM_HID_ItfTypeDef *)pdev->pUserData)->pReport;
}
if(req->wIndex == 1){ // 如果是接口1 则使用 键盘报表
len = MIN(HID_KEYBOARD_REPORT_DESC_SIZE, req->wLength);
pbuf=HID_KEYBOARD_ReportDesc;
}我们仿照USBD_CUSTOM_HID_SendReport() 函数 写一个键盘的发送函数。我们在usbd_customhid.c中可以找到这个函数，并仿照写出如下
uint8_t USBD_KEYBOADR_HID_SendReport(USBD_HandleTypeDef *pdev,
uint8_t *report,
uint16_t len)
{
USBD_CUSTOM_HID_HandleTypeDef *hhid = (USBD_CUSTOM_HID_HandleTypeDef *)pdev->pClassData;
if (pdev->dev_state == USBD_STATE_CONFIGURED)
{
if (hhid->state == CUSTOM_HID_IDLE)
{
hhid->state = CUSTOM_HID_BUSY;
USBD_LL_Transmit(pdev, HID_EPIN_ADDR, report, len);
}
else
{
return USBD_BUSY;
}
}
return USBD_OK;
}在main.c 中添加头文件，如果有则不用添加
#include "usbd_customhid.h" 在usbd_customhid.h中添加声明
uint8_t USBD_KEYBOADR_HID_SendReport(USBD_HandleTypeDef *pdev,
uint8_t *report,
uint16_t len);最后调用 USBD_KEYBOADR_HID_SendReport函数即可。我们在主函数中定义数组：
uint8_t KEYBOARD_Buffer[8]={0x00,0x00,0x04,0x00,0x00,0x00,0x00,0x00};
uint8_t KEYBOARD_Zero[8]={0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};调用函数
USBD_KEYBOADR_HID_SendReport(&hUsbDeviceFS, KEYBOARD_Buffer,8)
HAL_Delay(300);
USBD_KEYBOADR_HID_SendReport(&hUsbDeviceFS, KEYBOARD_Zero,8)代表了STM32这个键盘向电脑发送a。
自此，一个STM32上的USB连接电脑后电脑识别为两个接口，
一个是键盘，一个是自定义通信的设备。可以同时模拟键盘的同时与PC进行数据通信。
键盘的按键定义参考了链接
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
第一列10进制键值，第二列16进制键值，第四列是按键
