    Serial to parallel LCD converter

    marek.waskiewicz

      Hello ALL:))))

         

      this is my first post and MYFIRST  PROJEcT ,as well,

         

      I have got raw serial data from sanyo LC7981 LCD controller

         

      FLM:  A pulse on this line resets the frame position to top-left
      CL1 (LP): This triggers an increment in the line counter (Y position)
      CL2 (Clock): This shifts one pixel in through D and increments the pixel counter (X position)
      D (Data): The incoming data bits, one bit per display pixel

         

      Is it a SPI interface ?

         

      which wAs connected to graphic (240x64) serial LCD 

         

      but with EL backlight and not looks nice

         

      I would like to build converter serial to parallel graphic (240x64) LCD  using psoc 5lp
