I downloaded the Picade source from gethub https://github.com/pimoroni/picade-sketch
When I load the sketch and verify it I get a bunch of errors about variables not declared and libraries missing.
This is supposed to be the sketch currently running in the Picade.
How do I fix this? I just want to change a couple buttons.
