Dynamic font library optimization method based on single-chip microcomputer

Abstract

The invention provides a dynamic font library optimization method based on a single-chip microcomputer, and relates to the technical field of single-chip microcomputers, and the method comprises the steps of enabling the single-chip microcomputer to be connected with an upper computer through a serial port, enabling a user to input a to-be-displayed target character through a man-machine interaction interface of an upper computer development system, and uploading and storing the to-be-displayed target character into the upper computer; enabling the upper computer to call a built-in dot matrixlibrary to encode the target character to form a first code, and storing the first code; correcting the original data model in the upper computer by adopting a classification algorithm and taking thefirst code as training data to obtain a new data model, and obtaining a code instruction and an information code through the new data model; and enabling the single-chip microcomputer to download andcall the code instruction and the information code, and control the LED dot matrix according to the information code. The problems that in the prior art, a single-chip microcomputer excessively depends on a specific word stock chip in LED dot matrix control, so that cost is high, use is not flexible, and information processing efficiency is low are solved.

Description

technical field

[0001] The invention relates to the technical field of single-chip microcomputers, in particular to a single-chip microcomputer-based dynamic font optimization method. Background technique

[0002] In the application of single-chip microcomputer products, Chinese character information processing is very important, but at present, due to the cost of single-chip microcomputers, the internal Flash memory capacity is limited, and the Chinese font library is commonly used to reach more than 6000, and the font data is huge, so when using single-chip microcomputers to realize LED dot matrix control When displaying Chinese characters and patterns, the traditional method is to use a specific font chip. The single-chip computer reads the required font code in the matching font chip, and then realizes the LED dot matrix control display through the font code.

[0003] Although traditional methods can display Chinese characters and patterns, such methods rely too much on...
