(

bool

enable

)

Enable or disable EDID verbose output.

Useful for debugging and getting information about the sink.

Parameters

[in]

enable

- True to enable sending EDID information to the serial connection, false to disable it.

ADIAPI_mw_edid_get_audio_info()

void ADIAPI_mw_edid_get_audio_info

(

struct edid_audio_info *

audio_info_ptr

)

Get the audio information about the last parsed EDID.

Parameters

[out]

audio_info_ptr

- Pointer to the EDID structure where to copy the information.

ADIAPI_mw_edid_get_info()

void ADIAPI_mw_edid_get_info

(

struct edid_info *

info_ptr

)

Get the information about the last parsed EDID.

Parameters

[out]

info_ptr

- Pointer to the EDID structure where to copy the information.

ADIAPI_mw_edid_parse()

uint8_t ADIAPI_mw_edid_parse	(	uint8_t *	edid_ptr,
		uint16_t *	spa_offset,
		uint8_t	seg_num )

Parse and display the EDID message received.

Parameters

[in]	edid_ptr	- Pointer to the EDID message.
[out]	spa_offset	- Pointer to the SPA offset or 0
[in]	seg_num	- EDID segment number.

Returns

number of total additional segments, 0 if none or if checksum error in segment 0

ADIAPI_mw_edid_parse_silent()

uint8_t ADIAPI_mw_edid_parse_silent	(	uint8_t *	edid_ptr,
		uint16_t *	spa_offset,
		uint8_t	seg_num )

Parse the EDID message received without displaying to the terminal.

Parameters

[in]	edid_ptr	- Pointer to the EDID message.
[out]	spa_offset	- Pointer to the SPA offset or 0
[in]	seg_num	- EDID segment number.

Returns

number of total additional segments, 0 if none or if checksum error in segment 0
