Abstract
A single line docking station characteristic identifier is disclosed. In one embodiment, a portable computing device can include a dock detector circuit having an interface pin configured to be coupled to a docking station via a single line dock connection, where the dock detector circuit is configured to determine a characteristic of the docking station using a passive component in the docking station when the portable computing device is connected to the docking station via the single line dock connection. The dock detector circuit can include a resistor and a Schmitt trigger, while the passive component in the docking station can include a capacitor, for example.
Claims20
A portable computing device, comprising:
- a dock detector circuit having an interface pin configured to be coupled to a docking station via a single line dock connection, wherein the dock detector circuit is configured to determine a characteristic of the docking station using a passive component in the docking station when the portable computing device is connected to the docking station via the single line dock connection.
A method of determining a characteristic of a docking station, the method comprising:
- connecting a portable computing device to the docking station via a single line dock connection, wherein the portable computing device comprises a dock detector circuit coupled to the single line dock connection;
- placing the single line dock connection in a reset state using the dock detector circuit;
- and
- determining the characteristic by sampling the single line dock connection at a predetermined time.
A system of determining a characteristic of a docking station, the system comprising:
- a single line dock connection coupled to the docking station;
- and
- a portable computing device having a dock detector circuit, wherein the dock detector circuit is coupled to the single line dock connection, and wherein the dock detector circuit is configured to determine the characteristic using a passive component in the docking station when the portable computing device is connected to the docking station via the single line dock connection.
