5359That's because DIG returns the numeric value of the number, not the ASCII value. ASCII values are what is actually displayed to the user and what is expected by the LCD display. For example, the numeric value of 5, is, well, 5. Where as the ASCII value that causes a '5' to be displayed on the screen is a decimal 53. So when you move the results of DIG, let's say 5, to the LCD, you are really sending an ENQ code. Decimal 05 is ASCII for Enquiry, a flow control character.

So, how do you get 05, to be 53 so that the LCD will display '5'? The easiest way is to add the digit to the literal "0". (that's a zero) So an ASCII "0", which is a decimal 48, plus a decimal 5, is a decimal 53, which is an ASCII "5". Got it? The code would look something like this:

I'm not sure how lucid the above is. I'm fighting a head cold and not thinking to well. But hopefully you follow what I'm trying to say. If not, just post back, somebody will help.

5Thanks. The answer is so obvious now that you have shown it to me. I did know that the LCD required an ASCII number. That's what I thought I was giving it. I am now a little wiser.
