@kintel thanks for the half-duplex example. Looks pretty good. I've annotated a few lines with minor style issues (line length, brace position). Ready to merge after updates.

LGTM. I'm going to merge this so I can finish adjusting license text. Open a separate issue/PR if the hardware test reveals a bug.
