Function Documentation

s32 MIOS32_USB_MIDI_ChangeConnectionState ( u8 connected )

This function is called by the USB driver on cable connection/disconnection

Parameters:

[in] connected status (1 if connected)

Returns:: < 0 on errors

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions

s32 MIOS32_USB_MIDI_CheckAvailable ( u8 cable )

This function returns the connection status of the USB MIDI interface

Parameters:

[in] cable number

Returns:: 1: interface available; 0: interface not available

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions

Here is the call graph for this function:

void MIOS32_USB_MIDI_EP1_IN_Callback	(	u8	bEP,
		u8	bEPStatus
	)

Called by USB driver to check for IN streams

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions

Called by STM32 USB driver to check for IN streams

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions; also: bEP, bEPStatus only relevant for LPC17xx port

Called by STM32 USB Device driver to check for IN streams

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions; also: bEP, bEPStatus only relevant for LPC17xx port

void MIOS32_USB_MIDI_EP2_OUT_Callback	(	u8	bEP,
		u8	bEPStatus
	)

Called by USB driver to check for OUT streams

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions

Called by STM32 USB driver to check for OUT streams

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions; also: bEP, bEPStatus only relevant for LPC17xx port

Called by STM32 USB Device driver to check for OUT streams

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions; also: bEP, bEPStatus only relevant for LPC17xx port

s32 MIOS32_USB_MIDI_Init ( u32 mode )

Initializes USB MIDI layer

Parameters:

[in] mode currently only mode 0 supported

Returns:: < 0 if initialisation failed

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions

s32 MIOS32_USB_MIDI_PackageReceive ( mios32_midi_package_t * package )

This function checks for a new package

Parameters:

[out] package pointer to MIDI package (received package will be put into the given variable)

Returns:: -1 if no package in buffer; >= 0: number of packages which are still in the buffer

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions

Here is the call graph for this function:

s32 MIOS32_USB_MIDI_PackageSend ( mios32_midi_package_t package )

This function puts a new MIDI package into the Tx buffer (blocking function)

Parameters:

[in] package MIDI package

Returns:: 0: no error; -1: USB not connected

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions

Here is the call graph for this function:

s32 MIOS32_USB_MIDI_PackageSend_NonBlocking ( mios32_midi_package_t package )

This function puts a new MIDI package into the Tx buffer

Parameters:

[in] package MIDI package

Returns:: 0: no error; -1: USB not connected; -2: buffer is full caller should retry until buffer is free again

Note:: Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions

Here is the call graph for this function:

s32 MIOS32_USB_MIDI_Periodic_mS ( void )

This function should be called periodically each mS to handle timeout and expire counters.

For USB MIDI it also checks for incoming/outgoing USB packages!

Not for use in an application - this function is called from MIOS32_MIDI_Periodic_mS(), which is called by a task in the programming model!

Returns:: < 0 on errors
