Calculate the MODBUS RTU CRC-16 of a byte array slice.

from cubloc import GetCrc
 
GetCrc(arrayName: bytes, byteLength: int)

• arrayName: Source byte array.
• byteLength: Number of bytes from the start of arrayName to include.

Returns the MODBUS RTU CRC-16 value for the requested byte slice.

• TypeError: arrayName is not bytes or byteLength is not an integer.
• ValueError: byteLength is outside 1 to 65535 or larger than arrayName.

from cubloc import GetCrc
 
# Example usage
result = GetCrc([1, 2, 3], 1)
print(result)
