propose:
- if it's not too hard, "forget" on every enable (or disable) (fallback: beginstep/ends\
tep)
o doesn't handle the integ-det-pause cause, but that's hard and
we will make that clear to the scientists (eventual solution may be 1MHz encoder)
- turns out ric already does this
MHz Encoder Discussion
(with larry on oct 17, 23)
P,Q are limits
E error
A,B is for calculating position
Z is home
some get latched, there is a latch-clear
position is a signed integer
for errors have signal, counter and latch (only error is an error in encoding, likely because going too fast)
slaclab/high-rate-encoder-dev (devGui is there)
should we autohome (i.e. have firmware do it when it sees Z) or have scientists home it with software e.g. when absolute encoder is in the right place? maybe doesn't matter?
counter range is ~100 million.
