I use LattePanda with an integrated Arduino Co-processor: ATmega32u4 (Arduino Leonardo).
I use LV12.
I would prefer not to migrate to LV14.
Want to replace 6 virtual buttons with physical buttons accessed through the integrated Arduino Co-processor - via a dll or LV toolkit.
If you have a breadboard and some wires handy, this should be simple to write and put into production. If you don't, things may get a little more complicated.
