Implementation Method of μC/GUI Chinese Font Base on Embedded System

摘要

According to the current application of human-computer interaction interface is more and more complex requirements, implementation method of μC/GUI Chinese font based on the ARM embedded operating system with Cortex-M4F kernel is designed, to download the font by PC and embedded system USB to expand FLASH memory, the μC/GUI kernel code is modified and the GB2312 Chinese characters codec driver is added, this makes up for technical blank of Chinese display in embedded system with μC/GUI library, to provide an efficient and flexible solution for no character of LCD in embedded system. The method provides a reference implementation for other LCD controllers driver and font library transplantation in μC/GUI. Experiments show that, the design method of extended Chinese font provides reference for interactive LCD driver transplantation and font realization; it has better practicability and universality in environment of μC/GUI system.
