PCF8574_interrupt_advanced.ino 0.4.0 Breaking change Version 0.4.0 introduced a breaking change. You cannot set the pins inbegin()any more. This reduces the dependency of processor dependent Wire implementations. The user has to callWire.begin()and can optionally set the Wire pins before callin...

Despite the library's name, it supports the ESP8266, Attiny85, STM32F1 and should work with any standard Arduino-device at the moment, though, out of the official Arduino-boards, I have only tested it with Arduino Micro as I don't yet own any other ones. Usage What arguments the clas...
You can also use an interrupt pin: You must initialize the pin and the function to call when interrupt raised from PCF8574 // Function interrupt void keyPressedOnPCF8574(); // Set i2c address PCF8574 pcf8574(0x39, ARDUINO_UNO_INTERRUPT_PIN, keyPressedOnPCF8574); Remember you can't use...
