I made a program for psoc 5 where i used the char lcd, and was working fine, then i made some modifications and everything but the LCD worked. i made a new program that print a simple hello message and it didn´t work, i try changing the port and the lcd and nothing happened. i exported the hello program to psoc  and it worked fine. 

   

anybody have an idea of whats going on.

   

 

   

thanks.

Some pins of the PSoC5 Prototyping Kit are buffered with large capacitors. This will hinder LCD to work on those ports.

   

Look at schematic excerpt.
