I have started work on a new user interface for the ROV which will be hosted on the Raspberry Pi itself. For lack of a better name I am calling it Poseidon after the god of the sea. Initially, this is not designed as a replacement for QGC but more of a supplemental UI for doing some basic configuration and system health checks. I am very early in the build and just have simple things like checking the Pi CPU usage right now, but big plans for the future.
I welcome anyone else who would be interested in joining the development or if you just have ideas to share.
