Take your 0-255 unit

Multiply by 1412 into a Dummy Variable

Then use DIV32 to divide by 10

example...

255 x 1412 / 10 = 36006

If you multiplied by 14118 and divided by 100 you would be more accurate yealding...

255 x 14118 / 100 = 36000

Either results gives you two decimnal places (remember we're playing integers here, so the two decimal places are the rightmost two characters of the result.

That won't be minutes though... it'll be DECIMAL degrees... you'll have to do some more math to calculate that into minutes.

You have a POT that rotates exactly 360 degrees?
