todo
- email DG
- email GG - need EC30 new asic MILE without PULLY w/JST 0.8mm 12 pin cable.
- STAR MARKET - thyme packets,
- order flex cables
- make PCBs for eddy current sense
- measure resistance on boot (incorporate into mode2)
- implement thermal model, w/updates from resistance measurement.
- incorporate JR3 into LF
- get LF potential function
- for LF, if ABS - INC encoder error, then don't drop into mode 0!
- add "text code" into the ASC output from SWIFI
- pickle with robo config to make parameter restoration easier.
