摘　　要：为了解决驱动彩色液晶屏过程中因数据量大及引脚众多带来的设计复杂性、MCU内核利用效率低等问题,本文根据FSMC控制时序与8080协议时序的关系,采用了FSMC直接控制TFT彩色液晶屏的方法,利用STM32F103R6单片机进行软、硬件设计,控制JLX177彩色液晶屏显示英文字符及图片信息.通过硬件电路设计及软件程序编写完成了显示系统的设计,联合调试结果表明,该系统能很好的实现对图像及字符的显示功能.In order to rid the process of driving color LCD screen of the problems of design complexity and the low utilization efficiency of MCU kernel caused by the large amount of data and too many pins,the author adopts the method of FSMC direct control of TFT color screen according to the relationship between FSMC control timing and 8080 protocol timing,and uses STM32 F103 R6 SCM in soft-and hardware design,and to control JLX177 color LCD screen to display English character and picture information.The design of the display system is completed through the design of hardware circuit and the writing of the software program.The combined debugging results show that the system can nicely realize the function of the image and character display.
