Abstract

The invention is applied to the field of computer application and provides a multichip compatible method and a multichip compatible device based on capacitive touch press keys as well as electrical equipment. The method comprises the steps that triggering commands are detected at regular time; data are obtained after the triggering commands are detected; whether the data are a secret key or not is verified; if so, a plurality of key values are read and written; is not, whether the data are the key value or not is judged; if the data are the key value, press key instructions corresponding to the key value are executed; and if the data are not the key value, the operation returns to execute the step of detecting the triggering commands at regular time. The method, the device and the electrical equipment have the advantages that according to the promissory software protocol requirement, corresponding codes are written into an MCU (microprogrammed control unit) of the electrical equipment and a touch press key module, the MCU of the electrical equipment can automatically obtain the code values of each corresponding press key and store the code values into the corresponding region, so the code values of each press key of the capacitive touch press key module can be recognized, the module is compatible, the change of a software drive is not needed, and the problem of being compatible with different touch press key chips by electrical equipment adopting uneasy-to-change software is effectively solved.

Description

technical field [0001] The invention belongs to the field of computer applications, and in particular relates to a multi-chip compatible method, device and electrical equipment based on capacitive touch keys. Background technique [0002] Currently, capacitive touch buttons are used in many household appliances, such as TVs, fans, smart TV boxes, microwave ovens, etc., due to their simple and beautiful appearance, good operating experience, and waterproof function. Especially with the continuous development of capacitive touch key technology, there are more and more chip solutions that can be selected for the touch key module. [0003] However, in order to reduce the cost, or be affected by the stoppage of the chip, the touch button module will inevitably have to replace the chip solution. The current method for compatibility with the multi-chip solution is to integrate the software driver of the preset chip in the software, and the microprocessor (Micro Control Unit , MCU)...
