Resolved! "WHO_AM_I register value does not match the device selected"

My first time exploring with STEVAL hardware. I just received the STEVAL-MKI108V3 mother board, the STEVAL-MKI196V1 sensor board, and installed UNICO GUI 9.13.0 and FW Version V3.11.4. When starting the Unico Program with both "Automatic Port Detecti...

I3G4250D- PLLFILT required to be mounted for gyro to work

Hello, I am using the I3G44250D gyroscope without soldering the capacitors (C1=10nF,C2=470nF) and resistor (R2=10k) indicated for the PLLFILT, by using a configuration in which only the LPF1 filter is applied by default. With this configuration the g...

Resolved! What is the accuracy of the LSM6DSO timestamp frequency of 40 KHz?

There does not seem to be anything in the datasheet about set tolerance, or drift over temperature.  https://www.st.com/resource/en/datasheet/lsm6dso.pdfAssume the INTERNAL_FREQ_FINE is unchanged. It has a step size of .15%, so one would presume the...
