| 摘要 |
The present invention relates to a method and a device for capacitive near-field communication in a mobile device, capable of enabling communication between the mobile device and other nearby devices without adding parts and complex circuitry to the mobile device. The mobile device includes a conductive element and a ground node. The conductive element is configured to be detected by a proximity sensor. A switch is coupled between the conductive element and the ground node. The conductive element is coupled to the ground node by closing the switch. A first memory element is configured to control the switch. The first memory element includes a register bit coupled to a control terminal of the switch. A data output is configured to control the switch. A first-in, first-out (FIFO) provides data to the data output. The first memory element includes the FIFO. A capacitive touch controller is configured to measure a capacitance of the conductive element. A digital processing unit is configured to convert the capacitance of the conductive element to a bit of data. A second memory element is configured to store the bit of data. |
