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
代码语言：javascript复制//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

0xc0, // END_COLLECTION
0xc0 // END_COLLECTION*修改HID_MOUSE_REPORT_DESC_SIZE为117
3. 打开main.c
*设置全局变量
代码语言：javascript复制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
代码语言：javascript复制extern USBD_HandleTypeDef hUsbDeviceFS;*声明并建立函数void key_test_tunc(void)
代码语言：javascript复制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)
代码语言：javascript复制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));
}
}
