Using the STEVAL-MKI109V3 with MKI179V1 accelerometer daugther board, connected to PC via USB Lauching Unico GUI and selecting a device -> communication error probably due to an unappropriate driver What driver is to be used with Windows 10?

It should be related to the fact that you are using a pure accelerometer, the LIS2DW12. On this device, differently for example from 6-axis IMUs (e.g. LSM6DSOX), you don't have digital features such as the FSM, the MLC, etc...


And did you uploaded it on the ProfiMEMS?

Yes but for the mother board itself STEVAL-MKI109V3 ,I should have got the rev 3.42.4, correct?


Eventually I have updated , more than painful, the STEVAL-MKI109V3 (DFU) and now the FW rev = V3.42.4 is installed. I can see the correct rev on UNICO GUI and everything works fine.

My point: I don't understand why downloading the last rev of UNICO GUI from the website then lauching the corresponding .exe there is no automatic check on the STEVAL board of its current implemented FW rev to see if there is a match....

Any comment ?
