Detailed Description

Type define for an Audio class-specific MIDI IN jack. This gives information to the host on a MIDI input, either a physical input jack, or a logical jack (receiving input data internally, or from the host via an endpoint).

See also:

USB_MIDI_Descriptor_InputJack_t for the version of this type with non-standard LUFA specific element names.

Note:

Regardless of CPU architecture, these values should be stored as little endian.

Field Documentation

uint8_t USB_MIDI_StdDescriptor_InputJack_t::bDescriptorSubtype

Sub type value used to distinguish between audio class-specific descriptors.

uint8_t USB_MIDI_StdDescriptor_InputJack_t::bDescriptorType

Type of the descriptor, either a value in USB_DescriptorTypes_t or a value given by the specific class.

uint8_t USB_MIDI_StdDescriptor_InputJack_t::bJackID

ID value of this jack - must be a unique value within the device.

uint8_t USB_MIDI_StdDescriptor_InputJack_t::bJackType

Type of jack, one of the JACKTYPE_* mask values.

uint8_t USB_MIDI_StdDescriptor_InputJack_t::bLength

Size of the descriptor, in bytes.

uint8_t USB_MIDI_StdDescriptor_InputJack_t::iJack

Index of a string descriptor describing this descriptor within the device.
