[Open_electroporator] new platform PYFLEX_F401 coming together.

[John Griessen]

I just used a tool from ST Microelectronics called STM32CubeMX to double check that my pin setup and planning is right.
There are two screenshots committed to the repo:
https://github.com/kanzure/culture_shock/blob/master/hardware_schematics_layouts/STM32CubeMX-clocks.png
and STM32CubeMX-pins.png,
plus the project file,
PYFLEX_F401_definition.ioc,
which is pure text with all the STM32 signal names used in micropython.

That tool stops you from choosing impossible combinations, (so it stops you from wasting time).
It also will generate code in C with STM libraries, but I don't use that, (micropython instead).

If you want to use it, instructions are here, toward the bottom of the page under Software Development Tools:
