【摘要】：LED顯示屏是一種以通過控制半導(dǎo)體二極管的亮滅為顯示方式的顯示屏,可用來(lái)顯示圖形、圖像、文字、動(dòng)畫、視頻和錄像信號(hào)等各種信息。在信息大爆炸的今天,LED顯示的應(yīng)用得到了前所未有的發(fā)展,從街頭大型的廣告屏幕到室內(nèi)精美的LED照明燈,甚至手表、手機(jī)和電腦等和我們息息相關(guān)的電器產(chǎn)品也廣泛應(yīng)用了LED顯示屏,其充斥于我們生活的角角落落,同時(shí)也美化和方便著我們生活的方方面面。 LED顯示屏控制卡又稱LED顯示屏控制系統(tǒng)、LED顯示屏控制器,它是組成LED顯示屏的核心器件,主要用來(lái)接受來(lái)自計(jì)算機(jī)串行口等的畫面和顯示信息,并置入存儲(chǔ)器,按照分區(qū)的驅(qū)動(dòng)方式生產(chǎn)LED顯示屏能夠識(shí)別的顯示數(shù)據(jù)和控制時(shí)序。本文中作者基于ARM芯片LPC1765設(shè)計(jì)并實(shí)現(xiàn)了LED顯示屏控制卡,并在此基礎(chǔ)上對(duì)諸如行列滾動(dòng)和漢字的顯示等功能進(jìn)行了調(diào)試。 ARM芯片在作為控制卡的核心部件方面有著諸多優(yōu)點(diǎn),本文首先對(duì)芯片的選擇進(jìn)行了分析,之后設(shè)計(jì)了功能實(shí)現(xiàn)中所需要的各個(gè)模塊,如信號(hào)的行控制、列控制、串口和中斷系統(tǒng)等,并完成了實(shí)物卡的制作,最后是在Keil MDK上對(duì)下位機(jī)程序的編寫、仿真和調(diào)試,效果比較滿意。
[Abstract]:Led display screen is a display screen which can display graphics, images, text, animation, video and video signals by controlling the brightness of semiconductor diodes. In the information explosion today, the application of LED display has been unprecedented, from large advertising screens on the street to beautiful LED lights and even watches. Mobile phones and computers, and other electrical products that are closely related to us, are also widely used in LED display screens, which fill the corners of our lives. At the same time, it beautifies and facilitates all aspects of our life. The LED display control card is also called the LED display control system and LED display controller, which is the core component of the LED display. It is mainly used to receive pictures and display information from computer serial ports and put them into memory to produce display data and control time sequence which LED display can recognize according to the drive mode of partition. In this paper, based on arm chip LPC1765, the design and implementation of LED display control card, On this basis, the functions such as column rolling and Chinese character display are debugged. Arm chip has many advantages as the core component of the control card. Then every module is designed, such as line control of signal, column control, serial port and interrupt system, etc. Finally, the program of lower computer is written, simulated and debugged on Keil MDK. The effect is satisfactory.
