This Forum is Dedicated For all The Object Oriented PIC Lovers .......... The concept behind OOPic is straight forward. Use preprogrammed multitasking Objects from a library of highly optimized Objects to do all the work of interacting with the hardware. Then write small scripts in Basic, C, or Java syntax styles to control the Objects. During operation, the Objects run continuously and simultaneously in the background while the scripts run in the foreground telling the objects what to do.

Sounds like you want an itoa() clone. Byte or word data in, ASCII digits out.

Rather than build a string that you're just going to send to the LCD
and then throw away, you should go with itol() - integer to LCD. I
suspect you'll want to specify a field width: itol(value, width)

One function can handle bytes, signed words and unsigned words with
values less than 0x8000. If you need to handle all unsigned values,
there is a bit more work to do. The trick is to do this quickly
(you're using a 0.0003 MIPS processor) without using a lot of
variables - you don't want your formatting function eating up a
quarter of your data space.

Which way did you want to go? itoa or itol? Or the poor man's
substitute - Str$?
