Abstract

The invention relates to a key identification method, device and equipment and electrical equipment, and belongs to the technical field of key identification, and the key identification method, device and equipment and the electrical equipment are characterized in that a pressing level is acquired, and whether a key is pressed or not is judged according to the pressing level; if the key is pressed, judging whether the press of the key is raised or not according to the press level; if the keys are pressed and lifted, identifying effective pressing keys in the continuous pressing duration according to the preset pressing identification level range and the pressing level of each key; and identifying a target key in the effective pressing keys according to a preset key identification priority. According to the key recognition method and device, the effective pressing keys are recognized, and the key recognition priority is set, so that the target key is accurately recognized in the effective pressing keys, and the key recognition accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of key identification, and in particular relates to a key identification method, device, equipment and electrical equipment. Background technique [0002] In the equipment, control commands or setting parameters are often input through keys, for example, keys of household electrical appliances, keys of factory operating equipment, and the like. In the related art, button identification is usually performed through IO port acquisition mode or resistance voltage division identification. Among them, the IO port acquisition mode determines whether a button is pressed by collecting the high and low levels when the button is pressed. The recognition accuracy is high and it is not easy to make mistakes, but it occupies more IO port resources of the chip. The method of identifying buttons through resistor voltage division, the button and the resistor are combined to divide the voltage, and when different buttons ar...
