Using the STEVAL-MKI109V3 with MKI179V1 accelerometer daugther board, connected to PC via USB Lauching Unico GUI 9.13.0.0 and selecting a device -> communication error probably due to an unappropriate driver What driver is to be used with Windows 10?

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....

[LCari.1]

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

[Eleon BORLINI]

And did you uploaded it on the ProfiMEMS?

[LCari.1]

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 ?

[LCari.1]

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

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...

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