RELATED APPLICATIONS This application claims priority of U.S. Provisional Application Ser. No. 60/391,119 filed Jun. 24, 2002.
FIELD OF THE INVENTION This invention relates to an identification system for recognizing any one of a number of different types of devices at the terminal of an information handling system, and even further to the ability to reconfigure the terminal to service the identified device.
BACKGROUND OF THE INVENTION Audio processing has become an important function in the field of personal computers. Computers contain dedicated audio processing devices, typically referred to as audio codecs, which connect to external audio transducers and devices. One of the primary functions of the audio codec is to convert both input and output audio signals to and from the internal digital formats of the computer and the, typically, analog format of the external devices.
BRIEF SUMMARY OF THE INVENTION It is therefore an object of this invention to provide an improved identification system for recognizing any one of a number of different types of devices.
For a single jack one DC voltage path from the jack switch pins to the codec and one codec pin (JS) is sufficient to detect events at that jack. Connecting the switch pin on the jack to the JS pin will result in a logic high or low (high via pull-up resistor in the codec, low via pull-down resistor in the applications circuit) depending on if something plugged into the jack or not. The transition from logic �O� to logic �1� and vice versa is the event signal to the system.
FIG. 17 discloses resistive ladder 410 b for a multi-jack system 60 a′-60 n′ where the jack switch is not isolated from the audio signal. In this case, when nothing is in the jack the switch pins short the JS pin 400 path to the audio signal lines. If audio is playing, e.g., from an input device, this audio signal rides along the DC voltage causing it to change. RC filter 414 at JS pin 400 will decouple at least some of the AC audio signal and drain it to ground. Any voltage ripple or changes still at pin 400 could be �decoupled� by timer 416 inside codec 11 a with a timeout set such that jack event mis-detections caused by the residue audio riding the DC voltage will not occur. Logic circuit or means 418 is responsive to timer 416 and ADC 412 to check whether the output from ADC 412 has changed during a time period set by timer 416. If the ADC output continues to change over successive time periods, an audio signal is present and no JS interrupt signal is generated. Conversely if the ADC output has changed but remains stable, the JS interrupt signal is generated. This same solution could be used even with isolated jacks to reject noise.
