Embodiment 1

[0034] Such as figure 1 Shown is a flow chart of an embedded system multi-font text display method provided by an embodiment of the present invention, and the method includes the following steps:

[0035] Step S101, determining the types of fonts to be used and the non-duplicated characters in each font.

[0036] In the embodiment of the present invention, the fonts required by different embedded systems and the non-repetitive characters required under each font are different. The non-repetitive text required in this font.

[0037] In step S102, a dot matrix font library is established for each typeface, and a font information table is created for the dot matrix font library.

[0038] In the embodiment of the present invention, for each typeface, a dot-matrix font library is respectively established for storing the internal code and dot-matrix font data of the characters contained in the corresponding font. In the dot matrix font library, the internal code of a character is...

Embodiment 2

[0130] Such as image 3 Shown is the structural diagram of the embedded system multi-font text display system provided by the embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, including:

[0131] The determining unit 301 is configured to determine the types of fonts to be used and the non-repetitive characters in each font.

Abstract

The invention is applicable to the field of character display, and provides a display method and a display system for multifont characters of an embedded system. The method comprises the following steps that a current word stock information index table is preset; the currently used Chinese font and English font word stock information table address is stored into the current font information index table; character data of internal codes to be displayed is read; the currently used word stock information is obtained through the current word stock information index table, and the dot matrix data of the currently used word stock and characters are obtained according to the word stock information and the character data; characters are displayed according to the width and the height of the dot matrix character matrixes provided by the word stock information and the dot matrix data. When the method and the system provided by the invention are implemented, various character fonts can be displayed.

Description

technical field [0001] The invention belongs to the field of character display, and in particular relates to a display method and a display system for embedded system multi-font characters. Background technique [0002] In embedded system applications, in order to achieve a better human-machine interface, it is usually necessary to display Chinese and English characters in different fonts on different interfaces. [0003] The number of non-repetitive characters in the characters that the embedded system needs to display is usually small, and the storage capacity of the embedded system is usually small. In order to save the storage resources of the system, it is impossible to build a complete font library. For this reason, usually the existing text display method in the embedded system that adopts single font is: [0004] 1. Determine the text to be displayed; [0005] 2. Establish a dot-matrix font library and in-machine code table with no repeated text in a required font,...
