研华板卡的上位机labview程序，适合labview入门(upper computer labview program based yanhua company)

说明：  事件状态机(Event state machine)

利用Labview软件编写读取二进制文件程序(The Labview program reads the binary file)

CRC16的9个LabVIEW算法CCITT,CCITT-KERMIT,CCITT-X25，CCITT-XMODEM,DNP,IBM,MAXIM,MODBUS,USB，开发环境LabVIEW2013(9 LabVIEW algorithm of CRC16: CCITT,CCITT-KERMIT,CCITT-X25，CCITT-XMODEM,DNP,IBM,MAXIM,MODBUS,USB The development environment version is LabVIEW 2013)

说明：  串口自动换算CRC代码，编写时直接可以调用(Serial port automatically converts CRC code, which can be called directly when writing.)

数据实时采集，实现数据的动态记录，比如平均周期，峰峰值等(Real time data acquisition, dynamic recording of data, such as the average cycle, peak value, etc.)

FTP in Labview Application

说明：  对于labview编程者来说，需要解析hex文件需要额外翻查许多资料，本程序为labview程序，用来解析hex文件(labview program anlysis hex file)

数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresponding PWM duty cycle, and finally the speed of the motor is controlled.)

这个程序用于计算光声光谱声学腔的共振频率，方便实用(caculation of resonant frequency of acoustic resonator)
