Hi,
Yes, some peripherals have completely different internals (see the
difference between ADC on
F30x and F37x as one example - it is different peripheral with different
register sets). Moreover
F37x have Sigma-delta ADC as another peripheral added (do not be confused by
this peripheral
in the comparsion)
I see that Esden run many commits today, and master has been updated.
Thanks, esden ! If you
like to fork my branch, please wait some days, to give me some time to
synchronize and update
all my branches to have clean start for next work to be enabled it for
merging to master.
Regards,
Frantisek

I noticed the difference in the peripheral set between the F30x and the
F37x but are you saying that its more than which peripheral but how they
are implemented?

OK, I'll git clone master and start on this. Is your branch accessible?

Yes, its a board I designed and I used a STM32F372CC, I also have a
STM32F3Discovery board which has the STM32F303VC, it seems not as useful
for development as I had hoped.

Thanks Frantisek and best regards.
