## Functions
bool | MIDI_Device_ConfigureEndpoints (USB_ClassInfo_MIDI_Device_t *const MIDIInterfaceInfo) ATTR_NON_NULL_PTR_ARG(1)
| Configures the endpoints of a given MIDI 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 MIDI interface is selected.
void | MIDI_Device_USBTask (USB_ClassInfo_MIDI_Device_t *const MIDIInterfaceInfo) ATTR_NON_NULL_PTR_ARG(1)
| General management task for a given MIDI 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().
uint8_t | MIDI_Device_SendEventPacket (USB_ClassInfo_MIDI_Device_t *const MIDIInterfaceInfo, const MIDI_EventPacket_t *const Event) ATTR_NON_NULL_PTR_ARG(1) ATTR_NON_NULL_PTR_ARG(2)
| Sends a MIDI event packet to the host. If no host is connected, the event packet is discarded. Events are queued into the endpoint bank until either the endpoint bank is full, or MIDI_Device_Flush() is called. This allows for multiple MIDI events to be packed into a single endpoint packet, increasing data throughput.
uint8_t | MIDI_Device_Flush (USB_ClassInfo_MIDI_Device_t *const MIDIInterfaceInfo) ATTR_NON_NULL_PTR_ARG(1)
| Flushes the MIDI send buffer, sending any queued MIDI events to the host. This should be called to override the MIDI_Device_SendEventPacket() function's packing behaviour, to flush queued events.
bool | MIDI_Device_ReceiveEventPacket (USB_ClassInfo_MIDI_Device_t *const MIDIInterfaceInfo, MIDI_EventPacket_t *const Event) ATTR_NON_NULL_PTR_ARG(1) ATTR_NON_NULL_PTR_ARG(2)
| Receives a MIDI event packet from the host. Events are unpacked from the endpoint, thus if the endpoint bank contains multiple MIDI events from the host in the one packet, multiple calls to this function will return each individual event.
static void | MIDI_Device_ProcessControlRequest (USB_ClassInfo_MIDI_Device_t *const MIDIInterfaceInfo) ATTR_NON_NULL_PTR_ARG(1)
| Processes incoming control requests from the host, that are directed to the given MIDI class interface. This should be linked to the library EVENT_USB_Device_ControlRequest() event.
