Stylus and sensor controller

Abstract

A processor of a stylus according to the present disclosure detects a first signal supplied to a sensor electrode group in each frame. The processor determines whether the first signal represents a setting instruction of a local ID, and writes a value of the local ID specified by the setting instruction in a memory if the first signal is determined to represent the setting instruction. The processor repeatedly detects a second signal supplied to the sensor electrode group in each of one or more slots included in the frame. The processor compares values of a local ID included in the detected second signal and the local ID stored in the memory every time the processor detects the second signal, and transmits a first downlink signal to a sensor controller using an electrode if the values correspond with each other.
