DigitalOut

class

Mono variant of mbed::DigitalOut class, adding setMode() method.

This class is an extension of mbed’s DigitalOut class, adding an additional contructor and public method.

The additional function is the possibility to change the pin drive mode, such that it does not need to be strong drive (CMOS). This class allows you to set the mode to PullUp / PullDown / OpenDrain.

To see how you use the DigitalOut class, please refer to the mbed documentation page
