How to select I2C on STEVAL-MKI109V

[ola]

Hi All 

I am running Unicon GUI on Windows 10 and using it to communicate with STHS34PF80 sensor plugged onto STEVAL-MKI109V dev board.

I can fully interact with the senor via the GUI app. Meaning reading and writing all registers of interest.

I however want see what registers are being written and read by the GUI so I attached my logic analyzer to the I2C pins but unable to read any sensible data. So I am assuming that the motherboard is communicating over SPI. 

I want to be able to sniff the interaction between the GUI app and the  senor over I2C.

So what do I have to do to make the GUI change communication protocol.

Hi @ola ,

 

You can change the communication protocol in the Comm. & Power Settings tool window:

Hi Federica,

Looking at your image again. I noticed that you were using MEMS-Studio which is meant to have replaced the old Unico-GUI application that I was using. 

I have downloaded the MEMS-Studio and I can now read the I2C bus correctly. Thank you.
