1. Encoders
1.1. No Counts
For debugging encoders, first thing to look at is the rawcounts pin (with halmeter)
if it only toggles back and forth one count, this indicates that one of the A/B signals
is not getting to the counter.
1.2. DRO Reads Wrong
If rawcount counts up and down, but the DRO is wrong, then you likely have a scaling problem
