Descrizione

All, I was able to get the "generic nRF52" device to support the makerdiary.com nRF52832-MDK (which I got from Seeed Studio) by modifying the generic variant.h file to line up the various pins, especially the RGB LED and tx/rx pins for serial support. The modified variant.h is listed below. That was all I needed to modify to get everything I needed working.

Not so much an "issue" as hoping this helps someone else.

Sorry, I don't know the Arduino library/hardware structure well enough to create a whole new variant.

BTW, I hope you'll support the nRF52840-MDK soon, too!
