Member Function Documentation

◆ write() [1/3]

template<class Derived , class MessageTypeT , uint16_t MaxPacketSizeV>

void write ( MessageType msg )

Send a MIDI USB message.

May block.

Parameters

msg	The 4-byte MIDI USB message to send.

◆ write() [2/3]

template<class Derived , class MessageTypeT , uint16_t MaxPacketSizeV>

void write	(	const MessageType *	msgs,
		uint32_t	num_msgs )

Send multiple MIDI USB messages.

May block.

Parameters

msgs	An array of 4-byte MIDI USB messages to send.
num_msgs	The number of messages in the array.

◆ write() [3/3]

template<class Derived , class MessageTypeT , uint16_t MaxPacketSizeV>

template<size_t N>

void write ( const MessageType(&) msgs[N] )

inline

Send multiple MIDI USB messages. May block.

Definition at line 32 of file BulkTX.hpp.

◆ write_nonblock()

template<class Derived , class MessageTypeT , uint16_t MaxPacketSizeV>

uint32_t write_nonblock	(	const MessageType *	msgs,
		uint32_t	num_msgs )

Send multiple MIDI USB messages without blocking.

Parameters

msgs	An array of 4-byte MIDI USB messages to send.
num_msgs	The number of messages in the array.

Returns: The number of messages that were actually sent.

◆ send_now()

template<class Derived , class MessageTypeT , uint16_t MaxPacketSizeV>

void send_now ( )

Try sending the buffered data now.

Start transmitting the latest packet if possible, even if it isn't full yet. If the latest packet is empty, this function has no effect.

uint32_t getWriteError ( ) const

inline

Get the number messages that failed to send.

Definition at line 54 of file BulkTX.hpp.

◆ clearWriteError()
