stm32 hid游戏手柄程序
用USB键盘程序修改成了 USB游戏手柄，是3轴 12按钮的
用手头的STM32F103C8T6最小系统板 测试过 可以用了
USB每次传输5字节
1：x轴
2：y轴
3：滑块
4 ：按钮 1234
5 ：按钮5678 9 10 11 12
需要修改的地方很多 我就不详细说了
提供一个程序工程下载的链接

醉经升级了WIN10系统，发现识别不了USB手柄了
修改下面的描述符就可以了
const u8 CustomHID_DeviceDescriptor[CUSTOMHID_SIZ_DEVICE_DESC] =
{
0x12, /*bLength */
USB_DEVICE_DESCRIPTOR_TYPE, /*bDescriptorType*/
0x00, /*bcdUSB */ 改成0x00
0x02, 改成0x02
0x00, /*bDeviceClass*/
0x00, /*bDeviceSubClass*/
0x00, /*bDeviceProtocol*/
0x40, /*bMaxPacketSize40*/
0xF3, /*idVendor (0x0483)*/
0x04,
0x04, /*idProduct = 0x5750*/
0x01,
0x00, /*bcdDevice rel. 2.00*/
