Connect LCD character display to parallel port
Posted: Thu 04 Feb 2010, 16:19
Hello, I'm here again with my second application with Puppy Linux and Gambas2 visual Basic environment. The program was developed on PC Engines Alix-1D motherboard (very low power consumption); this small application is freely available for download on my website http://ficara.altervista.org/linux_free.php#lcd20x4 in form of full working folder, with sources, for the Gambas2 environment. It's a basic implementation, but the source is very simple and can be easily expanded. It will be nice if you leave a reference to my work in your application if use the sources for your own projects. Hope this will be interesting for someone, bye 
. In my applications I use the normal VGA output. The backlight of LCD displays can be substituted by white leds, so the CF lamps and the inverter can be removed. I've seen some project on the internet with such argument. In the near future I will add to my site other applications using the parallel port under puppy linux on Alix board. My target is to make the "Puppy Mobile", a moving, smart device with image capturing and internet control. Step-by-step, easy to reproduce by all puppy lovers. I discovered Puppy just a month ago, but is FANTASTIC for embedded applications, so... GO ON.
