- It is symmetrical. The same circuit could be used for a PCB with one switch multiplexer, four encoders and a single VFO simply by removing half of the circuit. This will make it much easier to devise a min-controller in due course.
- Similarly, it is easy to create more complex boards using the same circuit "building block" approach.
- The Arduino is mounted directly onto the PCB using its header pins. No additional wiring should be required other than a USB connector to the Arduino and HDMI into the display (if fitted).
Meanwhile, I am adding code to the Windows side of the Mk II controller. This has thrown up the usual flurry of issues that confronts any software developer but each day a little more functionality is completed. More on this in due course.
