i dont know if anyone has create this idea into a vi, but i thought that if you wanted to control an U8 data byte value to a digital potentiometer that would be nifty...
basically double click on your slider maximum value and enter it (for example: 10Kohms =10000), it would output a U8 value (0-255 max) at the wiper or ( 0ohms- 10Kohmsmax)
