cubeMX配置流程

pinout&configuration

打开cubeMX
芯片选择stm32f103c8te
pa1引脚设置为GPIO_EXTI1
NVIC中使能EXTI line1 interrupt
RCC中HSE选择Crystal/ceramic Resonator
SYS中Debug选择serial wire
USB中勾选Device（FS）
USB_DEVICE中Class选择HID
设备描述符修改vid和pid的值（避免和连接到电脑上其他usb设备冲突而引起错误）
GPIO中pa1配置成Pull-down(按键接3.3v和pa1中间，若配置成Pull-up，则按键接gnd和pa1中间）

clock Configuration

PLL选择HSE
PLLMul选择x9
USB Prescaler选择/1.5
SYSCLK选择PLLCLK
最终配置结果usb48MHz，SYSCLK72MHz，检测无错

project manager

填写project名称

2.设置project Location

ToolChain/IDE选择MDK-ARM v5.27
code Generator 分别选择 copy only the necessary library files 和 Generate peripheral initialization as a pair of '.c/.h' files per peripheral
生成代码并打开项目

打开MDK-KEIL5

打开usbd_hid.c
修改USBD_HID_CfgFSDesc（HID设备全速配置描述符）

*USB_HID_CONFIG_DESC_SIZ 大小改为41U

*Descriptor of Joystick Mouse interface 中端点数量改为0x02,接口协议改为0x01

*配置描述符末尾新增输出端点描述符

3. 修改报告描述符HID_MOUSE_ReportDesc

*替换报告描述符内容为

//将整个报告描述符复制替换过去， 其中键盘REPORT_ID是1，鼠标REPORT_ID是2
      0x05, 0x01,                    // USAGE_PAGE (Generic Desktop)

*修改HID_MOUSE_REPORT_DESC_SIZE为117

3. 打开main.c

*设置全局变量

uint8_t KeyBoard[9] = {1,0,0,0,0,0,0,0,0};
uint8_t KeyBoard01[9] = {1,0,0,0,0,0,0,0,0};
uint8_t Mouse[9] = {2,0,0,0,0,0,0,0,0};

*引入外部变量

extern USBD_HandleTypeDef hUsbDeviceFS;

*声明并建立函数void key_test_tunc(void)

void key_test_func(void)
{
    KeyBoard[3] = 8;//e,修改并发送KeyBoard[3]的值触发不同按键
    USBD_HID_SendReport(&hUsbDeviceFS,(uint8_t*)&KeyBoard,sizeof(KeyBoard));
    HAL_Delay(15);
    USBD_HID_SendReport(&hUsbDeviceFS,(uint8_t*)&KeyBoard01,sizeof(KeyBoard01));
    HAL_Delay(100);
}

*声明并建立函数void mouse_test_func(void)

void mouse_test_func(void)
{
    Mouse[3] = -2; //up
    for(int count = 0;count<0x40000;count++)
    {
        USBD_HID_SendReport(&hUsbDeviceFS,(uint8_t*)&Mouse,sizeof(Mouse));
    }
}
