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:
