基于 STM32的μC/OS_II 与μC/GUI 整合移植与显示优化
Display optimization and transplantation of μC/OS_II and μC/GUI for STM32
摘要
Abstract
In order to create an efficient,intuitionistic and multi-mission embedded development plat-form,the embedded experimental environment was designed based on the μC/OS _ II,μC/GUI, STM32 MCU and ILI9320 LCD.Research was done to explore the migration method of the μC/OS_II and μC/GUI and to optimize the μC/GUI on the lack of the Chinese and low rate of the screen re-fresh.The organizational structure of the μC/OS_II and μC/GUI were studied,and the files that were closely associated with stm32 mcu were rewritten.At the same time,the operation of the μC/GUI transplantation was done based on the success of the transplantation of the μC/OS_II including the modification of the files related to the μC/OS _ II and the adaptation of the μC/GUI bottom-driven functions.And Chinese font library was added to the system based on the successful transplantation of the μC/GUI.The μC/GUI functions of drawing pixel,line and rectangle were rewritten to increase the screen refresh rate.The experimental results show that the four created tasks run regular services, and the Chinese character displayed normally.The screen refresh rate increased from 996 080 to 1 629 060 pixel/s.The μC/OS_II and μC/GUI worked cooperatively and the optimization of the μC/GUI functions improved the screen's performance.关键词
