Hello Rossw

Let me add one thing to NavMicro's info...

BE VERY CAREFUL on which LCD you purchase!!!

Some LCD's draw a tremendous amount of current...
For example the All Electronics LCD-69 is a LCD I would NOT purchase (I have two of them, and don't know what to do with them). Each one draws 350 MILS of current!!!! that will ruin a 7805 rather quickly if it is not heat sunk. I ruined 2 7805's before I figured out what was going on. My Old LCD that was 10 years old worked wonders, and the total current draw on it (with my chip and everything else) was only 10 mils.

If you read the review, take away a few resisters and such, they say you can get the current drain down to 150 mils <g> Which is STILL extremely high.

BUT!, it is a very nice LCD... very nice... You don't need any contrast adjustment at all...
