display and board picture :: Lcd controller; connect 20x4 character LCD to parallel port

Puppy_Gambas_LCD.tar.gz (9.77KB)
  • I use the Alix-1D motherboard for embedded applications, with Puppy Linux OS and Gambas2 visual Basic IDE. It's very easy to connect an LCD character display to the parallel port of the motherboard. There is a PIN STRIP connector, named J14, that provides all the signals for the parallel port. In my application I used the Hitachi LM044L display connected to the board in this way:
        DB7..DB0 - Data bus, connected to 'D7..D0' of LCD
        /STB - Strobe, connected to 'E' of LCD
        /SCI - Slct-in, connected to 'WE' of LCD
        /AFD - Auto-LF, connected to 'RS' of LCD
        GND - Signal ground, connected to 'VSS' of LCD
        The +5V supply can be taken from pin 4 of connector J15

The downloadable file contains the whole project folder with sources for Gambas2. This is a minimal working implementation; you have two buttons on the form: the first is for display initialization / clear, the second writes an incrementing character each time you click it, every time moving to next available LCD cursor position.
Look at my page
linux_howto for a small tutorial on Gambas2 environment installation.
