Generally the F4 and the F1 can be thought of as having no common
peripherals. That is exacerbated by the way in which libopencm3 came to be
in that each "type" is in many ways its own little universe of APIs and
peripherals. Some work has been done to create common interfaces but much
work remains to be done. The ADC system in particular has undergone a lot
of changes that Karl Passon put in. If I were starting on a project like
this I would treat it as a port between two completely different systems,
fewer surprises that way, take the F1 code, figure out what it wants to do,
then read the F4 Doxygen API and figure out how to do that on an F4. Then
write new code.
