Overview of this book

NI LabVIEW's intuitive graphical interface eliminates the steep learning curve associated with text-based languages such as C or C++. LabVIEW is a proven and powerful integrated development environment to interact with measurement and control hardware, analyze data, publish results, and distribute systems. This hands-on tutorial guide helps you harness the power of LabVIEW for data acquisition. This book begins with a quick introduction to LabVIEW, running through the fundamentals of communication and data collection. Then get to grips with the auto-code generation feature of LabVIEW using its GUI interface. You will learn how to use NI-DAQmax Data acquisition VIs, showing how LabVIEW can be used to appropriate a true physical phenomenon (such as temperature, light, and so on) and convert it to an appropriate data type that can be manipulated and analyzed with a computer. You will also learn how to create Distribution Kit for LabVIEW, acquainting yourself with various debugging techniques offered by LabVIEW to help you in situations where bugs are not letting you run your programs as intended. By the end of the book, you will have a clear idea how to build your own data acquisition system independently and much more.

9. Alternate Software for DAQ

DAQ devices versus microcontrollers

It is now almost over a decade and a half since microcontrollers have no longer been limited to digital I/Os. Mixed signals, control bus memory, separate timers, and counters have pushed their way into traditional microcontrollers with a speed that is only limited by the die size and functionality required, and most certainly price.

It is an undisputable fact that in data acquisition, speed and accuracy are directly related to the actual hardware and processors used and, depending on the speed and accuracy intended, a user must use proper hardware/software. In other words, proper instrumentation is the key to meaningful Data Acquisition. However, speed and accuracy at any given time in history have been relative terms. The terms high speed and accuracy have been highly relative throughout recent years and what we mean by speed and accuracy today is far different from what they meant just a few years ago.
