    Using the PSoC 5LP with LCD with I2C interface

    frmsos_1565511

      Hi guys! I'm currently working on a project and I need to use a LCD display (the one I got is the 2004a)  that component uses a  expander for I2C-bus (PCF8574T), but I have some problems making it work. I'm using the CY8C588LTI-LP097  PSoC 5LP. My top design includes an I2C and an I2C LCD component  but I doesn't work.  I have tried to use the I2C LCD example but I couldn't make it work. Any kind of help will be much appreciated.

         

      PS: I attached the bundle of my project and the datasheets of both the 2004a and the PCF8574T.

         

      Thanks!
