|
//| ============================================
|

//|
|

//| The AnalogOut is used to output analog values (a specific voltage).
|
|
//|
|
|
//| Example usage::
|
|
//|
|
|
//| import nativeio
|
|
//| from microcontroller import pin
|
|
//|
|
|
//| with nativeio.AnalogOut(pin.PA02) as dac: # output on pin PA02
|
|
//| dac.value = 32768 # makes PA02 1.65V
|
|
//|
|
|
|
|
//| .. class:: AnalogOut(pin)
|
|
//|
|
|
//| Use the AnalogOut on the given pin.
|
|
//|
|
|
//| :param ~microcontroller.Pin pin: the pin to output to
