Add support for chip_id "0x444": "STM32F03xx4/6" #17

Closed omerk closed 5 years ago

omerk commented 5 years ago

As titled, a simple change to support chip id 0x444.

Curiously, these parts do not seem to have unique id support (no mention in the datasheet or the reference manual) so added a bit of logic to handle that.

Tested changes on a STM32F030F4P6 board (the common SSOP20 breakout board available ubiquitously, it seems), can confirm it working.

Thanks!

If you agree with my comments above, can you change and test it?

Tidied up get_uid() and format_uid() as discussed, with tweaks to the constant names.

Testing this on two boards I have here:

STM32F030F4P6:
