Hi Nitro,

Yes that is true, PBP assumes that the LCD is connected to PortA.0 to PortA.3 for the 4 bit data lines and RS to PortA.4 and enable to PortB.3. I have found throughout life not to assume anything! Put it in writing, as the lawyers say. Did you also disable the analog features? Do you have a pull up resistor on PortA.4?

It sounds from your last post that you have a more important problem. Hope the above helps when you have the other problems under control.
