Active pen communication method and device, terminal and storage medium

Abstract

The invention discloses an active pen communication method and device, a terminal and a storage medium, and the method comprises the steps: obtaining representation pressure information and a code fornib detection according to the pressure information when the pressure information is detected through a pressure sensor, wherein the code comprises n code bits; generating n coding signals corresponding to the n coding bits according to different pressures borne by a pressure sensor; and sending the n coding signals to a touch screen according to the same frequency. The pressure is expressed in adigital coding form, and meanwhile, the coding signals are transmitted by adopting the same frequency, so that in the transmission process, the same-frequency interference is avoided, and the normalwriting is ensured.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method, device, terminal and storage medium for an active pen. Background technique [0002] When the existing active pen transmits pressure information, it generally uses different frequencies to transmit different pressure information, which makes it easier to be affected by the environment when the active pen communicates with the touch screen, forming the same frequency interference, so that the active pen is in the same frequency range. When writing on the tablet is disconnected or even impossible to write, especially when the battery of the tablet is low or charging, the active pen is very easy to form the same frequency interference with the frequency of the power supply, resulting in occasional disconnection or even inability to write. The writing situation. Contents of the invention [0003] The embodiments of the present applicatio...
