This course aims to familiarize the students of any given specialized field with the basics of programming in LabView – a graphical development system widely used for data acquisition and process control in physics and technical laboratories as well as in industry. The lecture will emphasize practical aspects of the subject and will be centered around
the typical tasks facing an experimental researcher, i.e., automated control of measuring devices, as well as data acquisition, logging and processing. Practical programming excercises for students and their independent work.

To complete the course succesfully, it is required to obtain the credit ("zapocet") and to pass the examination. The credit must be obtained prior to, and is a requirement to taking the examination.
The credit will be awarded based on the implementation of a software program in LabVIEW. The specifications of the program will be assigned to each student individually. Generally, the idea of the program will be to control a device using LabVIEW. The program must satisfy the following criteria: functionality, documentation, readable implementation and efficient usage of LabVIEW (i.e., knowledge of LabVIEW functions and basic software architectures).
The program must be submitted before the date of the examination. Should the submitted program fail to meet the outlined criteria, the student is entitled to submit a revised version. Last update: Schmoranzer David, doc. RNDr., Ph.D. (11.10.2017)

The course will be completed by taking an oral examination. The examination will consist of one theoretical question, a detailed discussion of the implementation of the submitted program and one practical programming exercise.
The examination topics will cover the matter discussed during the lectures. Last update: Schmoranzer David, doc. RNDr., Ph.D. (11.10.2017)
