Abstract:
1. A method of transmitting a message from a digital-to-analog (D/A) converter configured to provide a first type of communication using an electrical analog signal to an analog-to-digital (A/D) converter electrically connected with the D/A converter, the A/D converter configured to provide digital data to a bus interface, the method comprising: powering down the D/A converter such that a voltage spike is generated in the analog signal and a digital adaptation of the spike is provided to the bus interface; powering up the D/A converter to ready the powered active component for a power down; and repeating the powering down and powering up steps to form a second type of communication according to a predetermined pattern corresponding to a message, the powering down steps generating a series of spikes in the data corresponding to the message.
