Embodiment Construction

[0031] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] First briefly introduce the starting point of proposing the technical solution of the present invention: on the one hand, with the continuous development of technology and the continuous increase of user needs, at present, home appliances have more and more functions, and the number of functional modules continues to increase, so that as home appliances The main processor at the core of product technology handles more and more tasks, and the interface resources of the main processor chip are becoming increasingly tight; Affect other modules, especially the main processing module. Based on the considerations of the above two aspects, the present invention proposes a method and a circuit for converting the state of the panel key into a coded signal, and then transmitting the coded signal to the main pro...

Abstract

The invention discloses a processing method of a panel key signal and a processing circuit thereof. The processing method comprises the following steps: detecting the state of panel keys; transforming the state of the panel keys into a corresponding code signal; and finally reading and processing the code signal by utilizing a main processor. In the invention, the panel key signal is processed by adopting the processing method and the processing circuit of the invention, thus solving the defects in the prior art that the keys on the control panel of a household appliance product occupy more resources of a main processor interface and a main circuit board requires to be changed when the number of the keys changes.

Description

technical field [0001] The invention relates to the processing of key signals, in particular to a method and a circuit for processing panel key signals. Background technique [0002] Home appliances such as televisions, set-top boxes, and players are all provided with a control panel, and a plurality of buttons are arranged on the panel, and users can use and control these home appliances by operating the buttons. In terms of circuit design, multiple buttons are connected to the I / O port of the main processor of the home appliance directly or through a button scanning circuit. Whether the button is pressed or not will generate different levels. The main processing reads the level status of its I / O port to detect whether there is a button pressed, and judges the type of button pressed, and then performs the corresponding button according to the button type. Process and control the home appliances to execute the functions corresponding to the buttons. [0003] Regardless of ...
