Speed is reasonably universal - is it not? Most always speed results from the formula: Number of impulses / unit time.

The QEI module aims to "automate" much of that process for you - and - in addition - provides direction knowledge.

You may review the source code w/in the various QEI functions - such will reveal the, "What, Where, When & How" of the QEI module functions...
