本文介绍了应用TP-801单板计算机实现对LED点阵显示器进行控制。实验结果表明,本显示器可以简单、灵活地实现三种颜色的变色显示,不但美观、醒目而且可以满足一些特殊场合的显示需要。字符大小、形状、颜色及字数可以由程序随意改变,从而显示出计算机控制——“万能逻辑电路”的优越性。在国内尚未见到同类工作的报导。
This article describes the application of TP-801 single-board computer to achieve control of the LED dot matrix display. Experimental results show that the display can be simple and flexible to achieve the three-color color display, not only beautiful, eye-catching and can meet the needs of some special occasions display. Character size, shape, color and number of words can be changed freely by the program, which shows the computer control - “universal logic” superiority. No reports of similar work have yet been seen in China.
