TFT液晶模块在风速测试系统中的应用

Application of TFT LCD Module in Wind Speed Test System

给出了STM32单片机控制下的TFT液晶模块的硬件电路,利用液晶模块代替上位机实现动态波形显示。软件设计介绍了液晶的地址映射和显示方式,动态波形显示包括采集数据的归一化、插值描点、更新方式。通过在风速测试系统中的实际应用,证明该系统可靠性高,具有良好的人机界面,同时提高了灵活性。

This paper presented the hardware interface of TFT LCD module in STM32 system,using LCD module instead of host computer to realize dynamic waveform display.About the software design,the paper introduced address map and display method of LCD,dynamic waveform display included collecting data＇s normalized,interpolation and draw dot,regeneration method.By practical application in wind speed test system,it proved that this system has high reliability,good human-machine interface,it also improved the flexibility.
