I have bpought a STEVAL-MKI109V3 + STEVAL-MKI105V1, but in UNICO Lite Rev. 3.0.0.0. I cannot find a selection for this kit, probably firmware of the board has to be updated. Cube Programmer is already installed, but where can I find the firmware imag

Ciao @stst9185​ ,

Unico Lite is graphical user interface software package, providing C# source code only for limited boards.

For the support of all the evaluation board for STEVAL-MKI109V3 (including STEVAL-MKI105V1), we suggest using the Unico-GUI software package instead.

After downloading the software package, you can find the firmware image in the “FIRMWARE/ProfiMEMSTool board�? folder.

Great, now I can select the right module!

It is a bit confusint, that there is a Unico software and a Unico-GUI software and they have different scopes of supported products.

Thanks!

It is reasonably easy to adjust the C# code for the Lite package to use another board, they are merely constants in the program. Also UNICO GUI does not give you timing, and the accelerometers I have run between 1200 and 1500 Hz for a 1666 Hz setting. You cannot rely on the timing signal from the board, the buffer stuffs the accuracy. It is actually an interesting statistical exercise to determine the rate. You cannot rely on the ratio of the different blocks as this can range from 1:27 to 1:33 on the one I use.

To write a program that gives you usable data you are looking at about 6 months solid work.
