I saw a few on some websites and they look pretty sweet. It looks pretty simple to install just plug in the serial port and power it, but what about the programs that are required to display the text, I suck at programming and don't want to have to write any code. Do they give you drivers/programs to run the LCD screen? Anyone know what a good one with like 4 lines of text with 20 characteres per line costs with blue back light?
