ACTIVE CAPACITIVE STYLUS, SENSOR CONTROLLER, RELATED SYSTEM AND METHOD |
摘要 |
A method may be executed by one or more active capacitive styluses and a sensor controller connected to sensor electrodes. The method includes: a discovery step, executed by the sensor controller, of repeatedly sending out a discovery packet for detecting any of the active capacitive styluses; a discovery response step, executed by a first active capacitive stylus among the one or more active capacitive styluses, by which the discovery packet is detected, of returning a response packet to the discovery packet; a configuration step, executed by the sensor controller, of transmitting a configuration packet including time slot designation information that designates a first time slot to the first active capacitive stylus; and a data transmission step, executed by the first active capacitive stylus, of transmitting operation state data indicative of an operation state of the first active capacitive stylus using the designated first time slot. |

1. A method executed by one or more active capacitive styluses and a sensor controller connected to sensor electrodes, the method comprising:
the sensor controller repeatedly transmitting a discovery packet for detecting any of the one or more active capacitive styluses; a first active capacitive stylus, out of the one or more active capacitive styluses, which has detected the discovery packet, transmitting a discovery response packet in response to the discovery packet; the sensor controller transmitting a configuration packet to the first active capacitive stylus, wherein the configuration packet includes time slot designation information that designates a first time slot whose reference timing is provided by the discovery packet; and the first active capacitive stylus transmitting operation state data indicative of an operation state of the first active capacitive stylus using the first time slot designated by the configuration packet. |
