摘要
本文介绍了一种适用于TP 801系列单板机的显示保持电路。在相应的软件支持下,可实现1～6位数字连续显示和1～5个键盘命令的设置。该电路使显示锁存与键盘扫描相互独立;不需要增加单板机上新的I/O口地址;具有电路简单、制作容易等特点。
A display-maintained circuit suitable for single-
board-computer TP 801 is presented, It is used to display one
to six bit digits continously, supporting in the software. This
circuit needn't increase new I/O addresses of the single-board-
computer, and its construction is simple and easy to be made.
