class DPCDRegion:

Class DPCDRegion describe a byte range of DPCD registers. Allows saving DPCD data to dpd file format save_to_dpd, hex files format save_to_hex, dsc file format save_to_csv.

Arguments:
  • base - start DPCD address of byte range.
  • data - DPCD data of byte range.
DPCDRegion(base: int, data: Union[bytearray, int])
base
size: int

Returns length fo data.

Returns:

result of int object

def save_to_dpd(self, path: str):

Save DPCD data to 'dpd' file format.

Arguments:
  • path (str) - full path to file
def save_to_hex(self, path: str):

Save DPCD data to 'hex' file format.

Arguments:
  • path (str) - full path to file
def save_to_csv(self, path: str):

Save DPCD data to 'csv' file format.

Arguments:
  • path (str) - full path to file
class DPCDRegisters:

Class DPCDRegisters allows working with DPCD registers: writing write DPCD data to device, reading read DPCD data from device, loading load_from_file DPCD data from file.

DPCDRegisters( port_io: UniTAP.libs.lib_tsi.tsi_io.PortIO, base_ci: int, data_ci: int)
def write(self, base: int, data: Union[bytearray, int, list]) -> int:

Write transferred DPCD data to device from base address.

Arguments:
  • base (int) - start (base) address.
  • data (Union[bytearray, int]) - DPCD data.
Returns:

result of operation

def read( self, base: int, count: int) -> DPCDRegion:

Read DPCD data from base address in a certain quantity.

Arguments:
  • base (int) - start (base) address.
  • count (int) - quantity of DPCD bytes.
Returns:

object of DPCDRegion

@staticmethod
def load_from_file( path: str) -> Tuple[DPCDRegion, DPCDRegion]:

Read DPCD data from file. Supported formats:

  • DPD.
Arguments:
  • path (str) - full path to file.
Returns:

object of tuple with two DPCDRegion objects
