i2s_slave()

void i2s_slave	(	const i2s_callback_group_t *const	i2s_cbg,
		port_t	p_dout[],
		const size_t	num_out,

I2S slave task

This task performs I2S on the provided pins. It will perform callbacks over the i2s_callback_group_t callback group to get/receive data from the application using this component.

The component performs I2S slave so will expect the word clock and bit clock to be driven externally.

Parameters

i2s_cbg	The I2S callback group pointing to the application's functions to use for initialization and getting and receiving frames. Also points to application specific data which will be shared between the callbacks.
p_dout	An array of data output ports
num_out	The number of output data ports
p_din	An array of data input ports
num_in	The number of input data ports
p_bclk	The bit clock input port
p_lrclk	The word clock input port
bclk	A clock that will get configured for use with the bit clock
