Functions
static void	SetupHardware (void)
int	main (void)
	Main program entry point.
void	EVENT_USB_Device_Connect (void)
	USB Device connect event callback.
void	EVENT_USB_Device_Disconnect (void)
	USB Device disconnect event callback.
void	EVENT_USB_Device_ConfigurationChanged (void)
	USB Device configuration change event callback.
void	EVENT_USB_Device_ControlRequest (void)
	USB Device control request receive event callback.
void	EVENT_USB_Device_StartOfFrame (void)
bool	CALLBACK_HID_Device_CreateHIDReport (USB_ClassInfo_HID_Device_t *const HIDInterfaceInfo, uint8_t *const ReportID, const uint8_t ReportType, void *ReportData, uint16_t *const ReportSize)
	HID class driver callback for the user creation of a HID IN 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.
void	CALLBACK_HID_Device_ProcessHIDReport (USB_ClassInfo_HID_Device_t *const HIDInterfaceInfo, const uint8_t ReportID, const uint8_t ReportType, const void *ReportData, const uint16_t ReportSize)
	HID class driver callback for the user processing of a received HID OUT 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.
