Possible LCD use

Hello Guys

I found a handful of these in a junk drawer at work and was wondering if these can be used with BS2. While I am not an electrical engineer, I am not sure how to hook on up. The schematic in PDF form are here;

Hi Bill,

You should consider consider using a serial interface display with the stamp instead the one you posted. The serial interface display will be less programming, and you only need to connect 4 wires. Way less than compared to the 16 wires parallel interfaces use. The Matrix Orbital serial displays work very well with them, and you can purchase them at http://www.parallax.com/detail.asp?product_id=30058 or http://www.parallax.com/detail.asp?product_id=30057 , and www.matrixorbital.com . The application notes for interfacing Matrix Orbital displays with the Basic Stamp, show you how easy it is to work with. The app notes can be found at http://www.matrixorbital.ca/appnotes/basic_stamp/

Best Regards,

That lookslike a 4x20 parallel LCD.· If you want to send me one I'll hook it up to my Combo backpack and see if I can get it to work.

Do you have a Stamp Tester yet?

Before you go spending any more money -- perhaps unnecessarily -- download StampWorks (no charge) and try the LCD experiments. I'm a big believer of using what one has and if you're not in a pinch for I/O there's no need to buy an new display or a display driver.

A point in fact is that if that display is HD44780A-compatible, you can control it with six I/O lines and even read back from it if you can spare one more.

I have used an Emerging Display LCD (the maker of your displays) with success. While not the same model as yours (mine is 4 x 16) it appears to be· compatible with the HD44780 spec's/code.

The Stamp example code should work OK with it.

I have also connected it to a serial converter chip which only uses one I/O line from the Stamp and that works also.
