      Hello Guys,

         

       

         

      I have a question,

         

      How can I use the 16x2 LCD on PSOC 1 ?

         

      thanks

          If you have got a kit3210 you just connect the LCD-module to the pins. When you start from scratch I would recommend to have a look into the schematics for the above mentioned kit here http://www.cypress.com/?rID=2541&source=shop and follow the design as close as possible.

             

          You will need 7 bits of an io-port, preferrably P1 or P2 to connect an LCD.

            The LCD has to have an LCD controller on it, and be Hitachi/Renesas 44780

               

            controller compatible.

               

             

               

            For contrast adjustment you can use a simple pot or PSOC DAC to handle that.

               

            "Normal" contrast voltage is ~ .5 to 1 V referenced to ground.

               

             

               

            If you are shopping around for a display get the blue mode, white characters on a blue

               

            background, LED backlight (if you can afford the B/L power consumption), these displays

               

            look great compared to puke green displays we have been using since the disappearance

               

            of dinosaurs).

              PSOC can do a multiplexed LCD drive, eg. PSOC becomes the controller,

                 

              see -
