If the backlight works it's likely you connected it correctly.
The results follow, however, they are the same whether the hat is installed or not. As I mentioned above, I already had an IMU wired into the dAISy board.

What is really needed is documentation that explains how to hook everything up. I find Openploter to be very fragmented and unfriendly to the user. If it is to ever get beyond the programmer level, it will need to be simplified. For instance, I thought Pypilot was a plugin for OpenCPN. But there is a standalone and openplotter versions too, I guess. I don't really know what I am working with. How do these pieces fit together? What is the slave and what is the master?
You might find it useful to look at the guide in the thread called Pypilot for Dummys.
