I've searched in vain for a driver for the Cloudcap Crista IMU, so it looks like I will have to write/modify a driver to convert to ROS message format. I have a specific example driver in C++ that came with the unit along with several other source files as dependencies.

I have not been able to find specifics regarding the creation of the ROS wrapper that implements this driver. I can post the example code if need be.

Thanks in advance Bruce

06/15/15 Thank you Kleinma. I did find your driver about a month ago and am in the process of putting it all together with robot_localization. At first I had little luck, but after a late night AHA!, I discovered that it was timing-out due to the latency of my setup. It is working fine now after making that adjustment. Thank you so much, I thought I was the only one in the universe using this accelerometer. Also great work on the agricultural applications!

Thanks also goes to the ROS community at large. Such a gold mine of knowledge! I did not think I could mix cpp and python in ROS, but the answer was here within the community. I still have a long way to go, but now I have access to your wealth of resources and experience. Many thanks to all.

If you do start writing a wrapper/driver, please pay attention to standards / best practices for IMUs in ROS. See ros-infrastructure/rep#95 for some recent discussion on this.

You can find a ROS driver here. "Crista" is mispelled (as "Christa"). However, it should work just fine.
