Abstract

The invention provides a POS terminal power amplifier control method and system, electronic equipment and a storage medium, and the technical scheme of the method comprises the following steps: an executable file configuration step: compiling an executable file in an Android environment for modifying an audio digital volume control attenuation register of a POS terminal; a script file configuration step: a shell script is written in the Android environment and used for running the executable file, and the shell script is automatically started when the POS terminal is started; and a power gain control step: running the executable file through the shell script, and further modifying the audio digital volume control attenuation register through the executable file. According to the invention, the problems of high cost and low efficiency of the existing POS terminal power amplifier control technology are solved.

Description

technical field [0001] The invention belongs to the technical field of POS terminals, and in particular relates to a POS terminal power amplifier control method, system, electronic equipment and storage medium. Background technique [0002] On the POS smart terminal based on the Android system, in order to meet the terminal’s better playback effect in different public environments, it is necessary to achieve the best playback effect of the speaker in different environments. The existing technology is mainly through modifying the hardware circuit and debugging the system. The audio power is adapted to the scene, and modifying the hardware circuit will increase the hardware cost. In addition, because it needs to be debugged on the Android system kernel driver, the developer needs to modify the system, which will reduce the efficiency. Contents of the invention [0003] Embodiments of the present application provide a POS terminal power amplifier control method, system, elect...
