UniTAP.dev.ports.modules.edid.edid

class Edid:

Main class for working with EDID. Allows reading and saving EDID. This functionality is used by child classes EdidSource and EdidSink. You cannot use a class Edid object directly.

Edid( port_io: UniTAP.libs.lib_tsi.tsi_io.PortIO, control_ci: int, max_stream_count: int, select_stream_ci: int)
def read_i2c(self) -> bytearray:

Allows reading from DUT EdidSource or TE EdidSink side EDID block(s) over connecting signal cable.

Returns:

object of bytearray

def save_edid( self, path: str, file_type: UniTAP.dev.ports.modules.edid.edid_utils.EdidFileType, data: bytearray):

Save received EDID data into file. Supported formats:

  • BIN.
  • HEX.
Arguments:
  • path (str) - full path to file
  • file_type (EdidFileType) - one of the Supported formats.
  • data (bytearray) - EDID data for saving
def read_timings(self) -> List[UniTAP.common.timing.Timing]:
class EdidSource(Edid):

Class EdidSource inherited from class Edid. Allows read EDID from remote devices read_sbm, save received EDID data to file save_edid and read EDID from DUT read_i2c

EdidSource(port_io: UniTAP.libs.lib_tsi.tsi_io.PortIO, max_stream_count: int)
def read_sbm(self, stream: int):

Allows reading remote EDID block(s) of remote device(s) attached to DUT over connecting signal cable. stream = 0 - UCD local EDID stream > 0 - Virtual Sink's EDID

Arguments:
  • stream (int) - Virtual Sink index.

class EdidSink(Edid):

Class EdidSink inherited from class Edid. Allows writing EDID to device write_edid, load EDID data from file load_edid, save received EDID data to file save_edid and read EDID from TE read_i2c.

EdidSink(port_io: UniTAP.libs.lib_tsi.tsi_io.PortIO, max_stream_count: int)
def write_edid(self, data: bytearray, stream: int = 0):

Write transferred EDID to device.

Arguments:
  • data (bytearray) - EDID data for writing
  • stream (int) - Virtual Sink's EDID index
def load_edid(self, path: str, load_on_device: bool, stream: int = 0) -> bytearray:

Read EDID data from file. If needed to write data to device, select load_on_device = True. Supported formats:

  • BIN.
  • HEX.
Arguments:
  • path (str) - full path to file.
  • load_on_device (bool) - write loaded data to device or not.
  • stream (int) - Virtual Sink's EDID index
Returns:

object of bytearray

def read_sbm(self, stream: int):

Allows reading remote EDID block(s) of remote device(s) attached to DUT over connecting signal cable. stream = 0 - UCD local EDID stream > 0 - Virtual Sink's EDID

Arguments:
  • stream (int) - Virtual Sink index.

class DisplayIdSource(Edid):

Class DisplayIdSource inherited from class Edid. Allows read DisplayId from remote devices read_sbm, save received DisplayId data to file save_edid and read DisplayId from DUT read_i2c

DisplayIdSource(port_io: UniTAP.libs.lib_tsi.tsi_io.PortIO, max_stream_count: int)
def read_sbm(self, stream: int):

Allows reading remote DisplayId block(s) of remote device(s) attached to DUT over connecting signal cable. stream = 0 - UCD local EDID stream > 0 - Virtual Sink's EDID

Arguments:
  • stream (int) - Virtual Sink index.
def set_display_id_mode( self, mode: UniTAP.dev.ports.modules.edid.edid_types.DisplayIDReadMode):

Set DisplayID read mode

Arguments:
  • mode (DisplayIDReadMode)
def get_display_id_mode(self) -> UniTAP.dev.ports.modules.edid.edid_types.DisplayIDReadMode:

Returns DisplayID read mode.

Returns:

object of DisplayIDReadMode type.

class DisplayIdSink(Edid):

Class DisplayIdSink inherited from class Edid. Allows writing DisplayId to device write_display_id, load DisplayId data from file load_display_id, save received DisplayId data to file save_edid and read DisplayId from TE read_i2c.

DisplayIdSink(port_io: UniTAP.libs.lib_tsi.tsi_io.PortIO, max_stream_count: int)
def is_enabled(self) -> bool:

Returns status of DisplayId, is enabled or not.

Returns:

object of bool type.

def enable(self, enable: bool):
