一种在坐标系网格上实现动态波形显示的方法

Method of Realizing Dynamic Waveform Display on Coordinate Grid

为了实现对采样数据的显示,建立了一个基于STM32F103VET6和11cm(4.3in)TFT液晶模块组成的显示平台。针对动态波形和坐标系网格相交的点会被背景色填充掉的问题,提出了一种交点判别法,即对交点用网格颜色填充,非交点用背景色填充。通过在电缆参数集采控制系统中的实际应用,表明该方法能够解决网格被填充的问题,又避免了波形闪烁的现象,具有较好的实用性,满足动态波形显示的实时性要求。

In order to realize the sampling data display, a display platform consisting of STM32F103VET6 and 11 cm（4.3 in） TFT LCD module is established. For the problem of intersections between dynamic waveform and coordinate grid filled with background color, this paper propose a method of intersection identification, intersection filled with the grid color, non-intersection filled with the background color. By the practical application in the cable parameters acquisition and control system, it shows that the method can solves the problem of the grid being filled, but also avoid the flicker waveform, it has good usability, meets the requirement of real-time waveform display.
