Object based Protocol

The control interface to all maXTouch chips conforms to a standard system known as the Object-based Protocol (OBP), which defines how to interact with the various objects that are implemented on any particular chip.

It defines a mapping between registers and configuration values, and a way for objects to send status update messages to the host.

For a full description of the OBP for a particular device and firmware version, refer to the Protocol Guide issued for that device and version.
