Design of digital coding and decoding scheme based on flexible nixie tube with twenty-eight segments

为了满足PDLC型柔性数码管显示器的动态显示需求,提出一种简便的数字编解码方案,用于对4位7段柔性数码管显示内容的控制。运用对比研究和软硬件相结合的方法,设计了以51单片机为核心、锁存器和达林顿管阵列芯片为辅助器件的硬件电路系统以及对应的数字编码、解码方案,用C语言实现了该编解码方案的算法,并完成了软硬件调试任务。实验结果表明,柔性数码管可显示4位相同数字和4位不同数字,显示的内容完整清晰,这套编解码方案简易可行。

To satisfy the need for dynamic display of PDI.C flexible nixie tube, a simple scheme for digital coding and deco- ding is proposed to control the sevemsegment flexible nixie tube display figures. With the methods of comparison and combi- ning software with hardware,a control system based on 51 MCU is designed, which is combined with latches and Darlington transistor arrays, etc. The corresponding digital coding and decoding scheme based on this hardware platform is designed. Finally, the algorithm of this digital coding and decoding scheme is implemented by using C language, and the task for de- bugging software and hardware is completed. The results indicate that the flexible digital tube can display figures clearly. This coding and decoding scheme is simple and feasible.
