Background -https://github.com/RobTillaart/Arduino/issues/38 Special void toggle(const uint8_t pin)toggles a single pin void toggleMask(const uint8_t mask = 0xFF)toggles a selection of pins, if you want to invert all pins use 0xFF (default value). ...
The Arduino “Wire” library (https://www.arduino.cc/en/reference/wire) handles the I2C addresses a little differently. You only need to provide the 7 highest Bits of the I2C address, or it won’t respond to your calls. I hope it’s clear,you need to shift thebits of your address ...

The paper demonstrates some examples and explains the advantages of using I2C communication over parallel wiring. The paper also describes how to install the library on the Arduino 2 IDE following the instructions by Batutay (2023). Disclaimer The code and libraries provided by Bonezegei is ...

I took the code by Rob Tillaart from http://playground.arduino.cc/Main/PCF8574Class and modified it. Rob's original code is designed to work only with the first I2C-bus, but many devices now have multiple I2C-buses and on the ESP8266 the I2C is software-based, so you can have as ...
