  • Page 16: Software Programming Choices

    Chapter 1 Introduction Software Programming Choices There are several options to choose from when programming your National Instruments DAQ and SCXI hardware. You can use LabVIEW, LabWindows/CVI, NI-DAQ, or register-level programming. LabVIEW and LabWindows/CVI Application Software LabVIEW and LabWindows/CVI are innovative program development software packages for data acquisition and control applications.

  • Page 17: Figure 1-1. The Relationship Between The Programming Environment, Ni-Daq, And Your Hardware

    An example of a low-level function is writing directly to registers on the DAQ device. NI-DAQ does not sacrifice the performance of National Instruments DAQ devices because it lets multiple devices operate at their peak performance.

  • Page 18: Register-Level Programming

    LabWindows/CVI software is as easy and as flexible as register-level programming and can save weeks of development time.

    In the EEPROM there is a user-modifiable calibration area in addition to the permanent factory calibration area. This means that you can load the CalDACs with values either from the original factory calibration or from a calibration that you subsequently performed. National Instruments Corporation AT-MIO/AI E Series User Manual...

  • Page 109: Self-Calibration

    Your AT E Series board can measure and correct for almost all of its calibration-related errors without any external signal connections. Your National Instruments software provides a self-calibration method you can use. This self-calibration process, which generally takes less than a minute, is the preferred method of assuring accuracy in your application.
