) |
HID class driver callback for the user creation of a HID input report. This callback may fire in response to either HID class control requests from the host, or by the normal HID endpoint polling procedure. Inside this callback the user is responsible for the creation of the next HID input report to be sent to the host.
[in,out] | HIDInterfaceInfo | Pointer to a structure containing a HID Class configuration and state. |
[in,out] | ReportID | If preset to a non-zero value, this is the report ID being requested by the host. If zero, this should be set to the report ID of the generated HID input report. If multiple reports are not sent via the given HID interface, this parameter should be ignored. |
[out] | ReportData | Pointer to a buffer where the generated HID report should be stored. |
[out] | ReportSize | Number of bytes in the generated input report, or zero if no report is to be sent |

) |
HID class driver callback for the user processing of a received HID input report. This callback may fire in response to either HID class control requests from the host, or by the normal HID endpoint polling procedure. Inside this callback the user is responsible for the processing of the received HID output report from the host.
[in,out] | HIDInterfaceInfo | Pointer to a structure containing a HID Class configuration and state. |
[in] | ReportID | Report ID of the received output report. If multiple reports are not received via the given HID interface, this parameter should be ignored. |
[in] | ReportData | Pointer to a buffer where the received HID report is stored. |
[in] | ReportSize | Size in bytes of the received report from the host. |
bool HID_Device_ConfigureEndpoints | ( | USB_ClassInfo_HID_Device_t * | HIDInterfaceInfo | ) |
Configures the endpoints of a given HID interface, ready for use. This should be linked to the library EVENT_USB_Device_ConfigurationChanged() event so that the endpoints are configured when the configuration containing the given HID interface is selected.
[in,out] | HIDInterfaceInfo | Pointer to a structure containing a HID Class configuration and state. |
void HID_Device_MillisecondElapsed | ( | USB_ClassInfo_HID_Device_t * | HIDInterfaceInfo | ) |
Indicates that a millisecond of idle time has elapsed on the given HID interface, and the interface's idle count should be decremented. This should be called once per millisecond so that hardware key-repeats function correctly.
[in,out] | HIDInterfaceInfo | Pointer to a structure containing a HID Class configuration and state. |
void HID_Device_ProcessControlRequest | ( | USB_ClassInfo_HID_Device_t * | HIDInterfaceInfo | ) |
Processes incomming control requests from the host, that are directed to the given HID class interface. This should be linked to the library EVENT_USB_Device_UnhandledControlRequest() event.
[in,out] | HIDInterfaceInfo | Pointer to a structure containing a HID Class configuration and state. |
void HID_Device_USBTask | ( | USB_ClassInfo_HID_Device_t * | HIDInterfaceInfo | ) |
General management task for a given HID class interface, required for the correct operation of the interface. This should be called frequently in the main program loop, before the master USB management task USB_USBTask().
[in,out] | HIDInterfaceInfo | Pointer to a structure containing a HID Class configuration and state. |
