labview实现双通道数据采集回访系统，能够对采集到的数据进行回放分析(LabVIEW dual-channel data acquisition reciprocal system can playback analysis of the data collected)

说明：  基于Labview程序的HEX文件解析程序，可以基于此进行程序改进，编写程序下载上位机(Based on the hex file analysis program of LabVIEW program, the program can be improved, and the program can be written to download the upper computer)

说明：  客户觉得TestStand界面复杂，希望一个简单的界面即可进行序列执行，采用LabVIEW调用TestStand引擎可实现快速设计，将TestStand拆解到LabVIEW。 然而，这样做需要设计大量回调函数，开发较费时间，项目对时间要求很严格，且投入不多，故希望有快速解决方案。 为此，设计时希望LabVIEW可以充当一个辅助软件，可配置和控制执行，进行简单数据交互，执行还是TestStand进行(The customer thinks that TestStand interface is complex, and hopes that a simple interface can be used for sequence execution. Using LabVIEW to call TestStand engine can realize rapid design and disassemble TestStand to LabVIEW. However, to do this, a large number of callback functions need to be designed, which takes a lot of time to develop. The project has strict time requirements and little investment, so we hope to have a fast solution. Therefore, it is hoped that LabVIEW can be used as an auxiliary software in the design, which can be configured and controlled for execution, simple data interaction, execution or TestStand)

创建一个vi，实现对按钮状态的指示和按钮“按下”持续时间的简单计算功能，按下按钮时，对应的指示灯亮，对应的数字量显示控件中开始计时。松开按钮时，指示灯灭，计时停止。(Create a VI to realize the instructions of the button state and the simple computing function of the button "press" the duration. When the button is pressed, the corresponding indicator lights up, and the corresponding digital quantity displays the timing in the control. When the button is loosened, the light is put out and the timing is stopped.)
