Karl Palsson 04c92b6677 stm32f4: adc-dac-printf example

This is the same behaviour as the f1 and l1 examples of this code, making it
easier to test changes to unification of the adc code.

Console on PA2 (tx only)  115200@8n1

* Prints the ADC value on PA0 (adc channel 0) on the console
* Echos half that ADC value out to DAC channel 2 on PA5
* Prints the ADC value of PA1 (adc channel 1) to the console.

Recommended wiring:
* pot or any resistor ladder to PA0
* jumper from PA5 to PA1

example output:
