DigitalInOut

Mbed OS 2 and Mbed OS 5

This is the handbook for Mbed OS 2. If you’re working with Mbed OS 5, please see the Mbed OS 5 documentation. For the latest DigitalInOut API, please see DigitalInOut.

The DigitalInOut interface is used as a bi-directional digital pin, used to read the value of a digital pin when set as an input, or write the value when set as an output.

Any of the numbered mbed pins can be used as a DigitalInOut.
