BS2PX and Matrix Orbital Commands
Hello, I have a Matrix Orbital LK204-25 LCD from parallax and a BS2px. I have read over the documentation for the LCD but since I am new to LCDs I do not know how to begin writing code for the device. I know it has serial communication capabilities but the documentation also talks greatly about I2C commands (which I have never used and know very little about).

I am so confused! Could some one point me in the direction of something that could teach me the basics of writing code for LCD’s? Or even if some one had a small program written for this particular LCD that I could learn off of. It would be greatly appreciated!

Does any one have an entire sample program that I could take a look at?

Sorry, I'm not an I2C maven.

to compute the baud rate for various Basic Stamp Models. Make sure you have the data sheet handy of your display. If it's not posted on their web site then email them. I have a bunch of LCD2041's which are several hardware rev's behind the current model displayed on their web site. After I sent them an email, they provided me with the data sheet for my particular display.
Personally I would not mess with sending data to the display via I2C unless you have other I2C chips in your circuit and are running short on I/O pins.
Spend some time on their web site they have several examples on using their displays with the BASIC STAMP, in fact here is a link to their Basic Stamp info:

Hope this helps!
