摘要

视觉持续(POV)是一种相对较新的低成本概念，用于显示信息，而不是用于街道和商业部门的警告和广告的典型平面屏幕。这个想法是基于安装在平台上的许多led，这些led可以快速旋转，从而产生连续图像的错觉。在这个作品中，一个圆柱形的POV被呈现在空间(3D)而不是平面(2D)中来显示信息。其中一个具有挑战性的问题是将来自微控制器的控制信号的频率与电机速度同步，以产生无闪烁的显示，并具有足够好的分辨率，让观众区分不同的字符。利用Visual Basic开发了一个特殊的软件应用程序，在一个用户友好的环境中将硬件组件连接在一起。

Design and Implementation of a Cylindrical Persistence of Vision Display

Persistence of Vision (POV) is a relatively new and low cost concept to display messages instead of typical flat screens that can be used for warnings and advertisements in streets and commercial sectors. The idea is based on a number of LEDs installed on a platform that spins rapidly to create an illusion of a continuous image. In this work, a cylindrical POV is presented to show messages in the space (3D) rather than a plane (2D). One of the challenging issues is to synchronize the frequency of control signals from a microcontroller with the motor speed to result in a non-flashing display and have a resolution that is good enough to let viewers distinguish different characters. A special software application utilizing Visual Basic is developed to interface hardware components together in a user-friendly environment.
