MULTIPURPOSE SENSOR PORT

摘要

A sensor port is adapted to connect to either a sensor or a data source. A reader is configured to identify which of the sensor and the data source is connected to the sensor port. A data path is configured to communicate an analog signal associated with the sensor and digital data associated with the data source to a signal processor according to the identification made by the reader.
