No additional examples

	Read
Wait timeout ticks to receive length number of samples, returns samples received. 24 and 32-bit data must be split into two integer values per sample.
- INT	Data
Data array to populate with incoming data
- UINT	Length
Max number of samples to try and receive
- UINT	Timeout
Max number of ticks to wait for incoming samples
- UINT	Return

	CheckQueue
Checks the I2S Event queue for a DMA Buffer full or empty event. For an output returns true when there is an empty DMA buffer available. For an input return true when there is a full DMA buffer available.
- BOOL	Return

	Write
Wait timeout ticks to send length number of samples, returns samples sent 24 and 32-bit data must be split into two integer values per sample.
- INT	Data
Data array containing outgoing data
- UINT	Length
Max number of samples to try and send
- UINT	Timeout
Max number of ticks to wait for space in the outgoing buffer
- UINT	Return

	Start
Starts the I2S audio stream, auto started by the initialise function.
- VOID	Return

	Initialise
Configures the I2C peripheral ready for data.
- VOID	Return
