1、本科生毕业论文(设计)基于stm32控制文字的显示设计院系名称姓名学号专业指导教师年4月20日16摘要本文章主要介绍的是基于STM32的点阵LED屏的设计,主要采用的是搭载ARM公司能够最新的,具有先进构架的Cortex-M3内核的ARM系列主流32位的微处理器STM32作为该LED屏的控制核心,该微处理器具有出色的实时性能,优越的功效,高级的创新型外设和最大的集成性等,系统的主要模块有:电源模块、键盘模块、32乘32的LED点阵屏模块、STM32F103VCT6的主控硬件模块、显示模块、光笔硬件模块。各个模块能够实现LED点阵屏的亮度调节,多字填写,点亮屏幕,擦除错字,拖移文字,调节屏幕亮度
2、等功能,该系统可以直接通过光笔在LED显示屏上编写文字,进行信息输入,并且可以通过键盘进行各种功能的切换,使得普通的显示屏也具备了“手写”的功能,非常方便和实用。随着现代影像技术的日新月异,在现在舞台演出中,利用LED电子显示屏进行舞台活动已经屡见不鲜。在国外,捷克舞美设计家斯沃博达以运用影像进行舞台营造而著称,他对影像的运用已经达到了难以企及的高峰。 现在在国内舞台演出中运用LED电子显示屏已经非常频繁。它的表现力非常丰富:可以模拟实景,再现自然。也可以出现效果图像,还可以用来展现资料等等。因此手写点阵LED屏具有很大的发展前景。关键词: 单片机;点阵;LED;半导体发光二极管;动态扫描;图
3、文显示屏;AbstractThis article mainly introduces the design of the dot matrix LED display based on STM32, is mainly used to carry ARM new, has the advanced architecture of Cortex-M3 kernel ARM series of mainstream 32 bit microprocessor STM32 as the control core of the LED screen, the microprocessor has t
4、he excellent real-time performance, superior efficacy, senior innovative peripherals and maximum integration, systems main modules: power module, keyboard module, 32 x 32 LED dot matrix display module, main control module, STM32F103VCT6 display module, a hardware module. The brightness of each modul
5、e to achieve LED dot matrix screen control, many word to fill in, light up the screen, erase the typo, drag the text function, adjust the screen brightness and so on, the system can be directly through the pen to write the text in the LED display, information input, and can switch the various functi
6、ons through the keyboard, the screen also has a common the hand function, convenient and practical. With the development of modern imaging technology change rapidly, in the present stage, the stage of activities with LED electronic display screen has It is often seen. In foreign countries, the Czech
7、 stage design stage by using the image of Swoboda is famous for his creation, the use of image has reached beyond the reach of the peak. Now in the domestic stage in the use of LED electronic display screen has been very frequent. Its performance is very rich: can simulate the real, natural reproduc
