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 want to connect char lcd as per following pin configuration
D4 - 2.7
D5 - 2.6
D6 - 2.5
D7 - 2.4
Rs - 2.2
R/W - 2.1
Please help me.
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.
for the first project CY8C5868AXI-LP035 you connect the port P2.x
for the second project CY8C3866AXI-040 you connect the port P5.x
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.
