#190020 - What have you done so far
Responding to: Alexandre Marques's previous message
You get help when you try it yourself and get stuck. show us what you did and we will try to help and show you where you went wrong.
1st you have to learn how to use I2c bus then you have to read datasheet of PCF8574 which looks quite simple. You need to read!!!
Can you interface LCD with microcontroller directly first?
