Why not reference a const string?

need to convert the string to MSG_Data_t * which is consumed by the sspi module

This is dependent on the selected scale

actually, i don't think the scale matters in this, because this is a simple hysteresis on the Z value. Due to the orientation of the imu chip, any positive Z value means Sense has flipped or rolled.

is this register meant to be written to?

looks like its read only, will remove

are the units for these documented anywhere?

nope, i just saw a youtube video of a demo and copied the numbers.
documentation also does not show what the units are
drivers/imu.c
Outdated

undocumented rates go all the way up to 1.6 kHz (the resonant freq of the sensing element) but you get reduced resolution...

emits commands via SPI uart code
"tap"
and
"flipped [1|0]"
