Hi @LCari.1​ ,

can you see the STM32 board in the device manager?

And did you uploaded the last firmware update on the STEVAL-MKI109V3?

Hello ,

Yes for both.

In the meantime, I have installed the following : VCP_V1.5.0_Setup_W8_x64_64bits.exe and it works now.

But, normally I should not have done this according to STm video "Getting started with profiMEMS" explaining needed driver are already native in the files.zip

[Eleon BORLINI]

Those are the win8 drivers, the win10 has already embedded the STM32 drivers... or at least it should

Yes that 's what I understood as well. no need for W10

BUT, it didn't work , the port was enumeraed in Device Manager but no way to communicate....

By the way, I have posted another issue on the web case 00167097:

I have downloaded the UNICO GUI software to develop an apps using the accelerometer ref = LIS2DW12 with the STEVAL-MKI109V3 (Professional MEMS tool).

When clicking on the <Advanced Features> in option tab , the "current supply measurement / power supply" window does not pop up. No way to measure the current which is the basics.... Moreover, it enters in an never ending loop with UNICO is not responding !

Could you help on that one ?

Thanks

coming back to FW version: I have V2.18.6 coming with download of GUI UNICO V9.13.0.0.

Is it correct?

In the UM1049 I read 3.30.0

[Eleon BORLINI]

Hi @LCari.1​ ,

the associated Unico FW should be the v 3.42.4 version

-Eleon

[LCari.1]

Yes , I have the V3.42.4

[LCari.1]

The interface has many less tabs and options than the on described in the UM1049
