Hello. When this program runs I get the next error

io.write_pin(1,1)
File "/usr/local/lib/python3.7/dist-packages/ExpanderPi/ExpanderPi.py", line 702, in write_pin
self.__set_pin(pin, value, self.GPIOA, self.GPIOB)
File "/usr/local/lib/python3.7/dist-packages/ExpanderPi/ExpanderPi.py", line 440, in __set_pin
newval = self.__updatebyte(curval, pin, value)
AttributeError: 'IO' object has no attribute '_IO__updatebyte'

This error only occurs with this sentence: "write_pin", not with "read_pin" or "write_port" for example.

I think the Library instalation is correct because there is not error in "import ExpanderPi" and "set_port_direction"

Someone knows what the solution is?

Thanks

This is the code...

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import os, time, sys, glob
import ExpanderPi

io = ExpanderPi.IO()

io.set_port_direction(0, 0x00)
io.set_port_direction(1, 0x00)
io.set_port_pullups(0, 1)
io.set_port_pullups(1, 1)

print("Hello")

io.write_pin(0,1)
time.sleep(3)
io.write_pin(0,0)

Hello

Sorry, there was a bug with the Expander Pi python library. Please can you download the updated version from our GitHub repository and see if that fixes your problem?
