|

*
|
||||
* USBD_User_HID_0.c implements the application specific functionality of the
|
||||
* HID class and is used to receive and send data reports to the USB Host.
|
||||
*
|
||||
* The implementation must match the configuration file USBD_Config_HID_0.h.
|
||||
* The following values in USBD_Config_HID_0.h affect the user code:
|
||||
*
|
||||
* - 'Endpoint polling Interval' specifies the frequency of requests
|
||||
* initiated by USB Host for \ref USBD_HIDn_GetReport.
|
||||
*
|
||||
* - 'Number of Output Reports' configures the values for \em rid of
|
||||
* \ref USBD_HIDn_SetReport.
|
||||
*
|
||||
* - 'Number of Input Reports' configures the values for \em rid of
|
||||
* \ref USBD_HIDn_GetReport and \ref USBD_HID_GetReportTrigger.
|
||||
*
|
||||
* - 'Maximum Input Report Size' specifies the maximum value for:
|
||||
* - return of \ref USBD_HIDn_GetReport
|
||||
* - len of \ref USBD_HID_GetReportTrigger.
|
||||
*
|
||||
* - 'Maximum Output Report Size' specifies the maximum value for \em len
|
||||
* in \ref USBD_HIDn_SetReport for rtype=HID_REPORT_OUTPUT
|
||||
*
|
||||
* - 'Maximum Feature Report Size' specifies the maximum value for \em len
|
||||
* in \ref USBD_HIDn_SetReport for rtype=HID_REPORT_FEATURE
