    PSoC 4 Character LCD component

    user_24585443

      Hello,

       

      I am using a PSoC 4 Character LCD component to display some characters on a 16x2 LCD.

      My design is low power, so I am powering the whole LCD from one of the PSoC pins and shut down the power when not needed.

       

      However, I suspect there is a current leak on a control and/or data pins from the LCD port during the time the Vdd to LCD is cut off.

      What is the best way to switch all the control and data pins (on PSoC side) of the LCD port to active low or high impedance mode?

       

      The pins are tied to the component so I guess I can't define them one more time in the main.c

       

      Thank you,

      David
