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
|
