Module Contents

uds.utilities.conversions.bytes_to_hex(bytes_list)[source]

Convert a list of bytes to hex string.

Parameters:

bytes_list (uds.utilities.common_types.RawBytesAlias) – List of bytes to convert.

Returns:

String with provided list of bytes presented as hexadecimal values.

Return type:

str

uds.utilities.conversions.bytes_to_int(bytes_list, endianness=Endianness.BIG_ENDIAN)[source]

Convert a list of bytes to integer value.

Parameters:

  • bytes_list (uds.utilities.common_types.RawBytesAlias) – List of bytes to convert.

  • endianness (uds.utilities.enums.Endianness) – Order of bytes to use.

Returns:

The integer value represented by provided list of bytes.

Return type:

int

uds.utilities.conversions.int_to_bytes(int_value, size=None, endianness=Endianness.BIG_ENDIAN)[source]

Convert integer value to a list of bytes.

Parameters:

  • int_value (int) – Integer value to convert.

  • size (Optional[int]) – Number of bytes in the output. Use None to use the smallest possible number of bytes.

  • endianness (uds.utilities.enums.Endianness) – Order of bytes to use.

Raises:

  • TypeError – At least one provided value has invalid type.

  • ValueError – At least one provided value is out of range.

  • InconsistencyError – Provided value of size is too small to contain entire int_value.

Returns:

The value of bytes list that represents the provided integer value.

Return type:

bytes
