      Hi,

         

      How do I adjust the contrast ratio for my LCD screen with my dev kit?

         

      Thanks,

          Hi Jeff,

             

          In the board that has been shipped, the LCD contrast is set by the resistir divider, R69 and R68. This can be seen in the board schematic . To set the contrast manually,

             
                
          • R69 and R68 has to be removed
          •     
          • R67 has to be soldered. R67 should be a potentiometer of value 10k.
          •     
          • Adjusting R67, sets the contrast.

            Jeff,

               

             

               

            If you are using CY8CKIT-001 Developement kit, then the potentiometer R31 is used for LCD Contrast Adjust.
