Close enough, but not exactly, there's lots of the kinds of boards you 
describe that aren't arduino, but for the sake of this discussion, that 
definition fits well enough.

I wasn't aware any of the arduino boards were supported by FPC, I was 
actually tempted to mention to the op that FPC might not be a good 
development platform, due to lack of support for arduino boards, but 
since I hadn't checked to be 100 percent sure, I left that part out of 
my reply.

Good to know such support is present, that might make some of my 
projects more accessible to more platforms.

Where does one find the (limited) arduino support that is present in 
FPC? I'd be curious if any of the boards I have are directly supported.  
I realize the difference between arduino boards isn't all that 
significant, so support for one is at least partially accessible to 
other arduino boards.  How would one (possibly) contribute to increasing 
the number of boards supported?

I have probably half a dozen arduino boards here, along with the same 
number of raspberry pies, as well as micro:bit and propeller/basic stamp 
boards from parallax.  I'm now beginning to wonder if FPC could be 
adapted to work with the parallax propeller boards, since they aren't 
(functionally) all that different from arduinos, just been around a 
whole lot longer, and have more processors (in most cases)

This is probably a discussion better directed to the fpc-devel list, but 
I'm just curious how difficult (or easy) it would be to support other 
boards.
