VDDD tap: would prefer not haven’t an external regulator, breaks the vision a bit
we would like SCuM itself to work as a true single chip
do we get different results depending on the test (tapping a wire vs. using a power supply)
use a real wire
use the nRF:
pin to VDDD LDO out
high z, set 1, strobe from high z to active output, to high z, emulating tapping behavior
@David Burnett it that doesn’t work, we can use a voltage divider
discussion about previous tests
@Kristofer PISTER what did we do?
@Kristofer PISTER looks like the only difference is the duration of the tap
@Thomas Watteyne we could use the nRF to vary (sweep) the duration of the tap
@Kristofer PISTER we need to get the nRF up and running, and try with the 3-wire bus
@Austin Patel probably the next step is to use the nRF.
thoughts: people integrating on micro-robots may only need cold boot
low confidence this will work
looking to having the board work
@Kristofer PISTER let’s
@Kristofer PISTER can we put a resistor divider on the board so voltage from nRF goes down to 1.1V
@Austin Patel another pin which has the voltage divider, do can choose between straight to nRF, or voltage divider
@Fil Maksimovic use a break-out board of a regulator?
@Austin Patel will ask @Andrew Fearing
@Thomas Watteyne to write a UART pass-through snippet
@Thomas Watteyne to write a strobe snippet
