Labview for everyone graphical programming made easy and fun (travis, jeffreykring, jim)

LabVIEW là một ngôn ngữ lập trình đồ họa đã được chấp nhận rộng rãi trong toàn ngành công nghiệp, học viện và phòng nghiên cứu như là tiêu chuẩn cho việc thu thập dữ liệu và phần mềm điều khiển thiết bị. LabVIEW là một hệ thống phần mềm phân tích và thiết bị mạnh mẽ và linh hoạt đa nền tảng — bạn có thể chạy LabVIEW trên Windows, Mac OS X và Linux. Bạn cũng có thể chạy LabVIEW trên PDA (PalmOS, PocketPC hoặc thiết bị Windows CE), trên nền tảng thời gian thực và thậm chí nhúng các chương trình Lab VIEW vào chip FPGA và bộ vi xử lý 32 bit. Tạo chương trình LabVIEW của riêng bạn, hoặc công cụ ảo (VI), rất đơn giản. Giao diện người dùng trực quan của LabVIEW làm cho việc viết và sử dụng các chương trình trở nên thú vị và vui nhộn

Peter A Blume A perfect companion to LabVIEW for Everyone, 3/e, this book will help you understand why style is important, and show you how to bring good style to your LabVIEW applications The LabVIEW Style Book shows how to develop software that is more efficient and robust, more readable, and is easier to use, modify, and maintain Special attention is given to applications that are on an enterprise scale, as well as to the concerns that arise in team development Written from a practitioner’s point of view, the text is illustrated with many code snippets and complete examples from real-world applications The book will also help you prepare to pass the style part of the Certified LabVIEW Developer (CLD) and Certified LabVIEW Architect (CLA) exams Peter Blume is the founder and president of Bloomy Controls, Inc., which has been an active member of the National Instruments (NI) Alliance Program since 1992 They specialize in developing and integrating test, measurement,
