pcf8574

Este projeto implementa um sistema de display LCD utilizando o HD44780 com módulo I2C PCF8574 e um microcontrolador PIC18F25K50. O sistema fornece uma interface simples para exibição de texto em displays LCD através de comunicação I2C.

PCF8574 and PCF8575 support for Sming

That simple library let you use up to 5 DS18B20 sensors which are not on the same 1-Wire bus
