altos/stmf0: Re-implement fast ADC code for stmf02015-01-28T04:41:15+00:00Keith Packardkeithp@keithp.com2015-01-28T04:41:15+00:00urn:sha1:8ca1f234586225caea1040bc229b63491dadc1cb
This creates a ring buffer for ADC data so that ADC fetching can run
in parallel with other activities.

altos/usbtrng-v2.0: Use stmf042 hardware CRC unit2015-01-28T01:18:42+00:00Keith Packardkeithp@keithp.com2015-01-28T01:18:42+00:00urn:sha1:3749426af1e900a1b3354922fdd7e8b3bfa38084
Switch from software to hardware for CRC computation. I think this
must be faster, right?

altos/usbtrng-v2.0: Add random output command2015-01-27T06:16:18+00:00Keith Packardkeithp@keithp.com2015-01-27T06:16:18+00:00urn:sha1:ac1a58af4d281a9bc3572dc503982a94e439a4c1
Read chunks of random ADC data, do some CRC16 computations to de-bias
and merge 4 bytes of input data into 2 bytes of output data, then dump
that out over USB.
