STM32的USB库里定义了这样的一个结构体
typedef struct _USER_STANDARD_REQUESTS
{
void (*User_GetConfiguration)(void); /* Get Configuration */
void (*User_SetConfiguration)(void); /* Set Configuration */
void (*User_GetInterface)(void); /* Get Interface */
void (*User_SetInterface)(void); /* Set Interface */
void (*User_GetStatus)(void); /* Get Status */
void (*User_ClearFeature)(void); /* Clear Feature */
void (*User_SetEndPointFeature)(void); /* Set Endpoint Feature */
void (*User_SetDeviceFeature)(void); /* Set Device Feature */
void (*User_SetDeviceAddress)(void); /* Set Device Address */
}USER_STANDARD_REQUESTS;
但是在调用时似乎是一个数组的形式
USER_STANDARD_REQUESTS User_Standard_Requests =
{
Joystick_GetConfiguration,
Joystick_SetConfiguration,
Joystick_GetInterface,
Joystick_SetInterface,
Joystick_GetStatus,
Joystick_ClearFeature,
Joystick_SetEndPointFeature,
Joystick_SetDeviceFeature,
Joystick_SetDeviceAddress
};
可以这样调用的吗， |
