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.
