@Yu-Chi Lin presented slides
No apparent response over SPI from ADS 1299 eval board
Issue may be that ADS1299 communicates over SPI using falling edge sampling (CPOL = 0 and CPHA = 1) but most SPI code assumes rising edge sampling
The figure 2 on page 17 of the IMU datasheet (https://invensense.tdk.com/wp-content/uploads/2016/06/DS-000189-ICM-20948-v1.3.pdf) shows it sampling data on the rising edge of clock
@Alex Moreno presented slides
Not seeing expected capacitance at upper voltage range; proposing a test to ascertain capacitance at operational voltage (~1.8 V) instead of near zero volts.
Estimating fastest time at which LC tank can be re-tuned live during packet transmission
