update from @Yu-Chi Lin
- discussion about GPIO12 (stays low)
  - pin used as data out from SCuM to ADS board
  - @David Burnett issue seen can be explained by a number of things, but not something that can easily be fixed
  - discussion about order of connecting things to get firmware to run
  - SCuM gets signal from ADS board!
update from @Fil Maksimovic
- shows join procedure working!
- discussion about SCuM-to-SCuM communication: often, the second SCuM produces an end-to-frame event without a start-of-frame event, which causes it to fail. Does not happen when SCuM received from the OpenMote
update from @Alex Moreno
- Added filtering to better visualize code updates using Matlab-applied 10 kHz LPF. ~33 MHz IF (downconverted RF LO) now exhibits much clearer tuning code changes.
- 100 µF capacitor observed to fall to approximately 60 µF as VBAT rises
  - Trend also observed while VBAT falls
- Same filtering technique applied to better see FSK shifting
- Cadence simulations sweeping VBAT showing variation in LO frequency, current from VBAT, VDD_LO.
