This content relates to a deprecated version of Mbed
Mbed 2 is now deprecated. For the latest version please see the Mbed OS 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.
