Greetings, I have several electronic linear measuring scales. The resoultion of these devices is .0005". Accuracy is + or - .001". However, there are apparently 20480 pulses per inch coming from the scales when moved. This equates to about .00005" resolution. So I was thinking about mapping the scales. I have the equipment to move these scales in ..0001" increments with a non accumulating error of less than .00004" per step. So, if I wanted to have scale with 8 inches travel with ..0001" resolution it would require 80,000 measurements and somehow these measurements would need to be associated with the scale so that the digital readout would show how far the scale had actually moved to within .0001". Is this "mapping" something that could be easily and cheaply handled a PIC and an Eprom? I hope the above was not too vague. Thanks, Eric R Snow
