Editing Experimenting with Stepper Motors as Rotary Encoders using a PIC running BoostC Project (section)

== Possibly useful links ==

This program uses my: [[Serial Communications Library -- BoostC and 16F877A]]

[http://home.clear.net.nz/pages/joecolquitt/stepper_as_encoder.html Stepper Motor As Rotary Encoder]  seems to be same as [http://www.piclist.com/techref/io/sensor/pos/enc/stepper_as_encoder.htm Stepper Motor As Rotary Encoder] this seems to give a nice trick to greatly improve the sensitivity of the motor as encoder.   Might want to try this.

A free terminal program, I like this much better than hyperterminal:

BoostC – I think the free version is enough to compile the program:
