ah i am sure i did reply. er. yes

well although we used the pinmux it was for the benefits of autogenerating everything rather than actual IO muxing.

ahhh  that's a git submodule.  you _can_ set up git submodules to have commit access, it's not commonly done but does actually work, i have manually added to .git/config in submodule directories a master branch 

but yes.

but, first, we should have a wiki page and on it have the list of expected peripherals.  and put the Datasheets on it.

then from that, once agreed, see if the pincount is sane or insane (even if 256 it is still just about sane), check the packages that Europractices supports, and go from there.

theeen it is more appropriate to start the python program.

oh btw pinmux needs converting to python3, sigh.  lib2to3 may help there.
