Perhaps gimmicking up a HAL circuit with siggen or freqgen to drive the stepper, then compare the encoder input with the motor output? You probably don't need a sine wave, just drive the motor back and forth at a variable rate: siggen providing a sawtooth wave to freqgen? Surely it'd be more complex than that, but triggering on one edge of the motor output and looking at the corresponding encoder edges should be revealing... -- Ed http://softsolder.com ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
