Would a PIC type device and EPROM be appropriate for this?

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

Thanks For the reply. I'll look into the rabbit web site. Eric

yes, it can be done very simply with a PIC, no Eprom needed. PIC's are getting large these days with lots of goodies in them also you have the AVR's (Atmels)which are nice to play with. in any case, you need to get your self a Dev kit.. you may want to look into Rabit Kits., those are complete onboard CPU's loaded with memory, Networking etc..

GOOD DAY

We have added a PIC between an encoder & it's readout to adapt a standard encoder to a special PPR they worked on first install, for us a 1 day job to get it working/debugged

we also use a couple of bits on top of E-prom on another " Backgauge " product, to select the encoder input used, include Imperial / Metric

I have also used a E-prom to map the runnout error on a ball screw, however I don't think you want to correct for a faulty encoder.
