no_os_tdm_init()

int32_t no_os_tdm_init	(	struct no_os_tdm_desc **	desc,
		const struct no_os_tdm_init_param *	param )

Initialize the TDM communication peripheral.

Parameters

desc	- The TDM descriptor.
param	- The structure that contains the TDM parameters.

Returns

0 in case of success, negative error code otherwise.

no_os_tdm_pause()

int32_t no_os_tdm_pause

(

struct no_os_tdm_desc *

desc

)

Pause TDM DMA transfer.

Parameters

desc	- The TDM descriptor.

Returns

0 in case of success, negative error code otherwise.

no_os_tdm_read()

int32_t no_os_tdm_read	(	struct no_os_tdm_desc *	desc,
		void *	data,
		uint16_t	nb_samples )

Read data using the TDM interface.

Parameters

desc	- The TDM descriptor.
data	- The buffer to store the received data.
nb_samples	- Number of samples to read.

Returns

0 in case of success, negative error code otherwise.

no_os_tdm_remove()

int32_t no_os_tdm_remove

(

struct no_os_tdm_desc *

desc

)

Free the resources allocated by no_os_tdm_init().

Parameters

desc	- The TDM descriptor.

Returns

0 in case of success, negative error code otherwise.

no_os_tdm_resume()

int32_t no_os_tdm_resume

(

struct no_os_tdm_desc *

desc

)

Parameters

desc	- The TDM descriptor.

Returns

0 in case of success, negative error code otherwise.

no_os_tdm_stop()

int32_t no_os_tdm_stop

(

struct no_os_tdm_desc *

desc

)

Stop TDM DMA transfer.

Parameters

desc	- The TDM descriptor.

Returns

0 in case of success, negative error code otherwise.

no_os_tdm_write()

int32_t no_os_tdm_write	(	struct no_os_tdm_desc *	desc,
		void *	data,
		uint16_t	nb_samples )

Write data using the TDM interface.

Parameters

desc	- The TDM descriptor.
data	- The buffer with the data to be transmitted.
nb_samples	- Number of samples to write.

Returns

0 in case of success, negative error code otherwise.
