I am using the PIC16F877 with an 16x2 LCD module.  I am trying to display
the A/D results on the LCD, 4 numbers per each row.

What I did is that I set aside 32 bytes of memory and each byte of memory
represents one ASCII character on the LCD (16 bytes for Line 1 and the
others for Line2).  Then I store the A/D results in appropriate "coordinate"
in the memory.  After that, I "copy" the entire memory block (the 32 bytes
block) to the LCD.  Whenever I want to update a certain A/D number, I go to
its memory location and update the number, then do the "copy" to the LCD
again.

Is there a better way to do this?  There must be...

Another "pain" I have to go through is to convert the A/D number to ASCII.
Let say the A/D result is 173 decimal, I have to separate number 1, number
7, and number 3.  Then covert them to ASCII, then store them in the memory
block, then copy the memory block to the LCD.

There must be a better way to do this too, right?

Thank you in advance!
Thomas
