由于STM32CubeMX配置HID协议时，只能配默认值，以下为需要修改的地方
|
||
|
||
|
||
|
||
|
||
|
||
/*
|
||
*更改HID_FS_BINTERVAL轮询时间，每1ms更新一次
|
||
*/
|
||
|
||
更改usbd_config.h文件：
|
||
|
||
原：
|
||
#define HID_FS_BINTERVAL 0xA //10ms
|
||
|
||
改为：
|
||
#define HID_FS_BINTERVAL 0x01 //1ms
|
||
|
||
|
||
|
||
|
||
|
||
|
||
|
||
/*
|
||
*更改usbd_hid鼠标报文，使鼠标可以发送最大6字节数据，保证x,y轴移动数据不丢包
|
||
*
|
||
*全部复制粘贴
|
||
*/
|
||
|
||
更改usbd_hid.h文件：
|
||
|
||
#define HID_EPIN_ADDR 0x81U
|

#define HID_EPIN_SIZE 0x06U //最大数据为6Byte
