10. ni.com/training Course Goals This course prepares you for the following: Solve problems using LabVIEW Use data acquisition and instrument control in LabVIEW applications Use modular programming practices Develop, debug, and test LabVIEW VIs Effectively use a state machine architecture

11. ni.com/training TOPICS Lesson 1 Problem Solving A.Software Development Method B.Scenario C.Design D.Implementation E.Testing F.Maintenance G.Project

12. ni.com/training A. Software Development Method Problem solving skills essential to creating software solutions Computer programmers use a software development method Using the software development method, code is more likely to be successful, readable, scalable, and maintainable

13. ni.com/training Software Development Method 1.Define the problem (Scenario) 2.Design an algorithm or flowchart 3.Implement the design 4.Test and verify the implementation 5.Maintain and update the implementation

14. ni.com/training Software Development Method Used in all hands-on development exercises in this course Scenario and Design are usually given; you implement the design and test the implementation

15. ni.com/training B. Scenario Define the problem Furnace Example: You need to cure a material at a certain temperature for a set amount of time in a furnace. For this problem, you need not know the material type or the time of day. You must know the cure time, temperature, and method for adjusting the temperature.

16. ni.com/training C. Design Design a solution by analyzing the problem: Identify the software inputs Identify the software outputs Identify additional requirements Design an algorithm or flowchart

17. ni.com/training Design—Software Inputs Raw data you want to process, such as information received from the user, data acquisition, instrument control and so on Furnace Example: Cure Time (seconds) Desired Cure Temperature (degrees Kelvin) Current Furnace Temperature (degrees Kelvin)

18. ni.com/training Design—Software Outputs Results of calculations, processing, or other implemented conditions such as information displayed to the user, data written to file, signal generation, and so on Furnace Example: On/Off switch to control coil voltage

19. ni.com/training Design – Additional Requirements Factors that influence solving the problem Furnace Example: Assume the furnace cannot start until the interior temperature is the same as the exterior temperature. This requirement adds an additional input: Exterior Temperature (degrees Kelvin).

20. ni.com/training Design – Algorithm 1.Read exterior temp 2.Read interior temp 3.If interior temp ≠ exterior temp, repeat step 1 4.Read interior temp 5.If current temp > desired temp, turn off voltage to coil 6.If current temp ≤ desired temp, turn on voltage to coil 7.If time < cure time, repeat step 4 8.Turn off voltage to coil Steps that process your inputs and create outputs. Furnace Example:

21. ni.com/training Design – Flowchart Visual design of an algorithm Furnace Example:

22. ni.com/training Design – State Transition Diagram Type of flowchart that indicates the states of a program and transitions between states. State—part of a program that satisfies a condition, performs an action or waits for an event. Transition—condition, action, or event that causes the program to move to the next state.

23. ni.com/training Design – State Transition Diagram Furnace Example:

24. ni.com/training D. Implementation Create code for the algorithm or flowchart Course goal— to successfully create implementations in LabVIEW

25. ni.com/training E. Testing Test implementation with logical and illogical data –Does logical data produce expected result? –Does illogical data produce expected error? –How does illogical data affect the results? –Is error handling strategy sufficient?

26. ni.com/training F. Maintenance Ongoing process of resolving programming errors Implement changes to the original solution

27. ni.com/training GOAL Exercise 1-1: Software Development Method Solve a non-programming problem using the software development method described in this course.

28. ni.com/training GOAL Exercise 1-2: State Diagram Create a state transition diagram for a weather station. You build portions of the weather station throughout this course.
