| 摘 要： | 虚拟仪器的常规用法是由不同总线标准的NI数据采集卡与之配套使用。一般的仪器仪表大多以单片机为控制核心,不具备与虚拟仪器配套使用的条件。本文以ARM7的LPC2131嵌入式单片机控制的数据采集模块为例说明单片机与虚拟仪器串口通信的实现方法,该方法简单实用,即集合了嵌入式单片机实时性强、速度快的优点,又突显了虚拟仪器的特点,为虚拟仪器和基于单片机的仪器仪表的结合应用提供了一条途径。

| Abstract: | Conventional virtual instrument is used by different bus standard NI data acquisition card.Most general instrument controlled by microcontroller does not have matching conditions to use with virtual instruments.This paper introduces the serial communication method between the data acquisition module controlled by LPC2131 embedded MCU of ARM7 and the virtual instrument.The method is simple and practical.Its advantages is that it has a strong set of real-time embedded MCU and run fast and highlight the characteristics of virtual machines.It also provides a way to combine virtual instrument and instrumentation controlled by MCU. |
