A rather boring video of me rambling while spinning the VFO dial and seeing data for the first time.

The code driving the display can be found here:
https://github.com/hamspot/hr2510/tree/master/libraries/HR2510_PB112

It does not work like the standard LCD libraries despite being based on some of that code. It implements a set of methods that are specific to the HR2510 and the things it can display. I expect that there may be other versions of this library created with the same methods for Lincoln/2830, HR2600, TS-5010, CBS-1000, and other variants not listed. Some of the parts between those radios may be more easily interchanged with inexpensive adaptor boards through this project.

Pardon the crusty old HR2510 that has been beating around in the truck for a decade or so. But do notice that the above code is driving the display.
