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 BusInOut API, please see BusInOut.

The BusInOut interface is used as a bi-directional bus that collects together a number of DigitalInOut pins that can be read and written as one value.

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