The documentation for the SMC03A is a bit sketchy. In fact, it has been marked as preliminary for several years now.
What I would like to clarify is precisely how the serial commands drive the unit in Position Feedback mode:
- Does the “motor speed” parameter, 0 thru 7F, actually correspond to the position from 0 volts feedback to 5 volts feedback?
- What effect does the direction bit have on the behavior?
In reading the doc for the newer SMC04, there is the potential for more resolution by using the 4 byte code. Does the direction bit behave the same way with the SMC04?
