Protocol switching method, device and equipment and computer readable storage medium

Abstract

The invention discloses a protocol switching method, device and equipment and a computer readable storage medium, and the method comprises the steps: starting signal searching at an interval (namely a silent stage) when an active pen transmits a signal based on a current protocol, enabling the current signal transmission of the active pen not to be interfered, and guaranteeing the stability of signal searching operation; according to the protocol switching method and device, after it is determined that the external signal needing to be received exists in the silent stage, the external signal is received and recognized, the target protocol needing to be switched is determined, protocol switching is carried out at the proper switching opportunity (namely the opportunity meeting the preset protocol switching condition), and due to the fact that the recognition operation does not need much time, the protocol switching efficiency is improved. And the switching opportunity is properly selected, so that the stability and timeliness of the protocol switching process of the active pen can be further ensured, and the active pen can support the switching among the screen end protocols of various manufacturers more quickly and accurately.

Description

technical field [0001] The invention relates to the field of embedded technology, in particular to a protocol switching method, device, equipment and computer-readable storage medium. Background technique [0002] With the rapid development of electronic technology, active pens have also become electronic devices commonly used in people's daily life. Writing on the electronic screen with an active pen is essentially a process of communication and interaction between the pen and the screen. Since there is communication, there must be a communication protocol. The target communication protocol is based on the leading formulation of the screen, and the active pen and the screen perform wireless communication and interaction according to a certain communication protocol. However, there is no standard agreement that all screen manufacturers uniformly abide by. All major screen manufacturers have formulated their own agreements. As a result, users on the market can only buy activ...
