Hmvp	ffa97842e2	Improve clock frequency stuff for uninitialized clocks and add some examples (#64) ... * Improve clock frequency stuff for uninitialized clocks - Made clocks singletons so the frequency handling actually works as expected - Added initial frequencies - Improved the docs - Added a Clock trait * Add pico examples. These have the benefit of knowing which external crystal is attached. Even though it always should be a 12 MHz crystal. Thus we can setup the clocks properly I also changed the rp2040 examples to work out of the box for pico boards since that will probably be used most of the time	2021-07-26 20:24:58 +10:00
