RTOS/LAUNCHXL-CC2650: i2c hello world

Part Number: LAUNCHXL-CC2650
Other Parts Discussed in Thread: CC2650

Tool/software: TI-RTOS

Hi!

I'm totally stuck at adding an i2c sensor MPU9250 (like on the sensortag) to the launchpad. I'm a cc2650/ti-rtos beginner so excuse my stupid questions but I'm trying now for a couple of days and I'm unsure if it's me or a bug. In general I don't know where to start as there is way to much information...

Is there anyone willing to point me in the right direction and to show step by step how to access an i2c sensor starting from the bare project zero?

As far as I understand I need to add the i2c driver to the project at first. And there the problems start. How do I do that? When opening the appBLE_UartLog.cfg (is that even the right file?) the XGCONF editor starts but seem unresponsive. Clicking on "System Overview" does nothing/freezes the tab and "Driver Options" look like this:

Just some infos at the end:

I'm running MacOS. The target would be a custom board later but currently I'm trying to get it running on the cc2650 launchpad. The sensor is a MPU9250 which is the same as on the sensortag. The sensor works as I tested it with an simple arduino sketch. I have also two cc2650 sensortags if this helps to get me running.

Many thanks in advance!
