实验方法：
1、USB_HID协议免驱动，此例程不需要驱。
2、将跳线冒跳至USB_OTG,通过Micro USB 线将iCore1S USB-OTG接口与电脑相连。
3、打开上位机软件usb_hid.e，即可进行测试。
实验现象：
核心代码：
int main(void)
{ /* USER CODE BEGIN 1 */

MX_RTC_Init();
MX_USB_DEVICE_Init();
SystemClock_Config(); /* USER CODE BEGIN 2 */ /* USER CODE END 2 */ /* Infinite loop */
/* USER CODE BEGIN WHILE */

{
/* USER CODE END WHILE */ /* USER CODE BEGIN 3 */
