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 BusIn API, please see BusIn.

The BusIn interface is used to create a number of DigitalIn pins that can be read as one value.

Any of the numbered mbed pins can be used as a DigitalIn in the BusIn.
