What board do you have ?
You want the LCD to have a Hitachi / Renesas 44780 controller on it, then interface
is easy, 4 pins for data, 3 for control, one port of PSOC, one for contrast, 2 for power.
Or use the Kees component which allows general pin connection interface.
Or an I2C or SPI LCD, and you write the driver for it.
Use the Character-LCD component, that will work for that kind of display.
Do you have got a Cypress development Kit (which one) or are you using your own board?
If you look in the data sheet for the LCD component there is a connection
diagram shown. If you use Kees then the connections are flexible and
you choose what pins.
