But here it is now endangered ancient device, it makes people who saw her could not fet the display effect, exclamation, 40 years ago has even started creating endowed with such artistic breath, in order to make this ancient and very artistic devices send fail waste heat, POV clock according to glow tube design, this design used 80c52 chip as the core, the glow, according to the use of DS1302 realtime calendar clock chip to plete the basic function of the clock. This method has the advantage of reliable performance, good realtime, time, simple operation, easy programming. Understand the internal structure of singlechip microputer and program piling and simulation burning, etc, to better grasp the program structure and the modularized program design, for the development and application of singlechip microputer in the future to lay the foundation. KEY WORDS： Glow Tube, MCU, Programming, Design, Simulation， Electronic clock 2 目錄 前 言 .......................................................................... 0 1 輝光管簡介 ................................................................... 1 2 單片機及主要芯片相關(guān)知識 ...................................................... 2 .............................................................. 2 .......................................................... 2 .......................................................... 3 AT89C52單片機的介紹 ................................................. 4 主要芯片簡 潔 ............................................................. 7 2． 三極管 2N5551功能及引腳圖 ............................................ 8 十進制解碼器 HD74LS145芯片功能及引腳 .................................. 8 時鐘芯片 DS1302功能及引腳 ............................................ 10 PROTEUS 軟件簡介 .......................................................... 10 2． 3． 1 keilc51 軟件 ....................................................... 12 3 硬件電路設(shè)計 ................................................................ 13 ................................................... 13 ......................................................... 13 ............................................................. 14 ..................................
