  • Method Details

    • initialize

      void initialize()
      Perform any necessary initialization. (e.g. Setting pinmodes of digital output pins)

    • write4Bits

      void write4Bits​(byte value) throws IOException
      Sends a 4-bit value to the interface.
      Parameters:
      value - The 4-bit value to be transmitted over the LCD Interface
      Throws:
      IOException - Thrown when a problem occurs during transmission

    • write8Bits

      void write8Bits​(byte value) throws IOException
      Sends an 8-bit value to the interface.
      Parameters:
      value - The 8-bit value to be transmitted over the LCD Interface
      Throws:
      IOException - Thrown when a problem occurs during transmission

    • setRegSelectState

      void setRegSelectState​(LcdRegisterSelectState state)
      Sets the LCD's Register Select Pin state
      Parameters:
      state - The state of the Register Select Pin. Set to either LcdRegisterSelectState.COMMAND or LcdRegisterSelectState.DATA

    • setReadWriteState

      void setReadWriteState​(LcdReadWriteState state)
      Sets the LCD's Read/Write Pin state. Setting the state to WRITE will set the LCD RW pin to LOW while READ will set the LCD RW pin to HIGH.
      Parameters:
      state - The state to set (READ/WRITE) for the LCD RW Pin

    • setEnableState

      void setEnableState​(com.pi4j.io.gpio.PinState state)
      Sets the LCD's Enable Pin state
      Parameters:
      state - The PinState to set for the LCD Enable pin.
