You made your hardware-connections on Port5[0..6], but in your project you have assigned the LCD-pins to Port2[0..6]
So change your connections or re-assign the pins and it should work.

I am sure you need to connect D4 as well. The Character LCD component needs 7 bits on one port to work.

I think you have the control signals miswired.
Also dont forget the contrast pin connected to pot, set pot at mid range for initial setting.

This is for the LP 5 part but you can change it to a normal Psoc 5 by selecting the correct device in device selection.

Probably would be better to manually (programatically) shift the output-string. Will be a good practice to get acquainted to C-strings, pointers and all that stuff.

Is this an LCD display? if so you have to write all the instructions twice to the device. Check the Data Sheet.
