Communication method of circuit board and circuit board

Abstract

The invention specifically relates to a communication method of a circuit board and the circuit board, and a host computer, a slave computer and microcontrollers are provided. The host computer and the slave computer communicate with each other via a connecting line, the microcontrollers respectively communicate with the host computer and the slave computer via serial communication ports. The method includes the steps of powering up the host computer and the slave computer, sending a synchronous code from the host computer to the slave computer, the searching the corresponding rate parameters from the slave computer's storage rate parameter list according to the synchronous code received, and adjusting to the corresponding execution value and storing the execution value in the memory of the slave computer, executing the execution value after adjustment and sending the synchronous code to the host computer by the slave computer, and receiving and storing the synchronous code send by the slave computer and realizing the communication between the host computer and the slave computer by the host computer. The invention has the advantages that: 1. simplifying the communication by connecting the host computer, the slave computer and the microcontrollers and reducing the fault caused by connection; 2. realizing a unified connection interface which is compatible with different product interfaces, reducing computer types, giving convenience for maintenance, and lowering the cost.

Description

technical field [0001] The invention specifically relates to a communication method of a circuit board and the circuit board thereof. Background technique [0002] In the design of household appliances, such as air conditioners, water dispensers, washing machines and other electrical appliances, in the product design, the main peripheral equipment of the same type of products are similar, but for each specific product, in order to pursue individuality and diversity, industrial designers every The appearance, operation panel, and display button layout of a specific product vary greatly. [0003] With the improvement of people's living standards, there are more and more types of household appliances, and it is necessary to take both personalized diversity and standardization into consideration when designing products. [0004] The usual design method is to design the circuit of the power load part (hereinafter referred to as the power board) and the display key board (hereina...

AI Technical Summary

Problems solved by technology

In some products with complex functions and many input and output controls, the number of connections between the power board and the operation board will increase, which will increase the possible failure rate and increase the cost. Different products are incompatible with each other and the after-sales maintenance is complicated.
