| 中文摘要: |
| 针对传统LED点阵显示屏价格高、器件数目多及不易维护等问题,提出基于视觉暂留特性、以动态扫描方式完成旋转动态显示屏的设计方法。设计以STC12C5A32S2单片机为主控制模块,DS1302时钟芯片作为时间的设置与采集模块,DS18B20作为温度的采集模块,通过上位机进行图片和文字的转换和编辑,以单排高精度发光二极管的旋转实现了动态图像显示的功能。显示屏可实现动态文字、图像、实时时钟及实时温度的显示。 |
| 英文摘要: |
| In view of the high cost of traditional LED dot matrix display screen which has more components and is difficult to maintenance, a display of dynamic image by rotation of LEDs based on persistence of vision is presented. To realize the function of rotary dynamic image display, the design uses STC12C5A32S2 MCU as master control module, DS1302 clock chip as the time set with the acquisition module, and DS18B20 as the temperature acquisition module. The host computer are used for image and text changing and editing module. Single-row light-emitting diodes with high-precision are used as screen. The display screen can realize the functions of dynamic text and images, real-time clock and real-time temperature. |
