By default the example program use port 2. Did you change that?
yes. i have designed a pcb to connect with port 3. so i changed it. however it should work right?
P3.2 is connect C7 = 1,0nF capacitor on the board Kit-059, you must remove it
Thank you. i shall try it
Is this board your design or is it a PSOC CY8CKIT-059 PSOC 5lp Prototyping kit?
it is the prototyping kit. I have designed my board as per its pinouts
Logical Port Pin LCD Module Pin Description
LCDPort_0 DB4 Data Bit 0
LCDPort_1 DB5 Data Bit 1
LCDPort_2 DB6 Data Bit 2
LCDPort_3 DB7 Data Bit 3
LCDPort_4 E LCD Enable (strobe to confirm new data available)
LCDPort_5 RS Register Select (select data or control input data)
LCDPort_6 R/!W Read/not Write (toggle for polling the ready bit of the LCD)
Don't forget the 10K pot on pin 3 wiper and +5V and Ground across the Pot. My program uses port 2.
Thank you very much for your response..I have removed the on board capacitor as pavloven said, in port3 and connected LCD to it. Now its woking !!..Thank you pavloven

CY8CKIT-042: P1.7(C10) P4.2(C1) P4.3(C9)
CY8CKIT-049-42xx: P1.7( C3) P4.2(C2) P4.3(C11)
CY8CKIT-050: P0.2(J43) P0.4(J44)
CY8CKIT-059: P0.2(C12) P0.3(C13) P0.4 (C9) P3.2(C7) P5.4(C4)
I'm glad I could help you.
