I've cloned a project for the SAMD20.
When I try to build it in Microchip Studio V 7.0.2452, I get the error:
samd20.h: No such file or directory
The Device Pack Manager says that the SAMD20_DFP is up to date (SAMD20_DFP v 1.3.165).
But when I check the Project => Properties => Packs page, I see that it's blank -- that's probably the problem!
But here's the kicker: all buttons and fields are grayed out, so I don't see how to add the pack.
What am I missing?
