Function Documentation

s32 MBNG_SYSEX_Init

(

u32

mode

)

local variables This function initializes the SysEx handler

s32 MBNG_SYSEX_Parser	(	mios32_midi_port_t	port,
		u8	midi_in
	)

This function parses an incoming sysex stream for SysEx messages

s32 MBNG_SYSEX_SendAck	(	mios32_midi_port_t	port,
		u8	ack_code,
		u8	ack_arg
	)

This function sends a SysEx acknowledge to notify the user about the received command expects acknowledge code (e.g. 0x0f for good, 0x0e for error) and additional argument

Here is the call graph for this function:

s32 MBNG_SYSEX_TimeOut

(

mios32_midi_port_t

port

)

This function is called from NOTIFY_MIDI_TimeOut() in app.c if the MIDI parser runs into timeout
