摘要
本文介绍一种波形、字符和图形相结合的显示器的设计,它采用一种新颖的波形显示方法,最多可同时显示32路波形,具有示波器式的实时连续移动效果,但只占用极少量CPU时间,当信号的V/D采样停止时,波形显示自动冻结。显示器还可显示任意复杂的图表和文字。
This paper describes a design of a screen indicator which can be used to display wave- shapes, characters and graphs. A new method is adopted in waveshape display. As many as 32 wave lines can be shown simultaneously, and they have the real time flowing effect as in the oscilloscope. But it takes only a little time of CPU. When the A/D sampling of signals stops, the wave lines are frozen on the screen automaticaly. The indicator can also show any complx charts and patterns.
