+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:
