Learn LabView: Programming LabView - Shift Register - 3 views

  • As you move forward with LabView programming, you will see that most design patterns are impossible without the shift register. Anytime you are trying to keep track of something in a loop, you will need to use one.
  • The shift register is a key element of LabView programming. It allows looping structures, such as the For and While loop, to carry over values from one iteration into the next. This can be extremely powerful in allowing the developer to build up arrays of information, or retain state information about a program running in a loop.

Passing Data Between Loop Iterations in NI LabVIEW - National Instruments - 2 views

  •  
    When programming with loops, you often must access data from previous iterations of the loop in LabVIEW. For example, if you are acquiring one piece of data in each iteration of a loop and must average every five pieces of data, you must retain the data from previous iterations of the loop.

Sound sensor - 4 views

  • Both LEGO™ NXT sound sensors were placed at the same distance from the speaker. A very simple LabVIEW NXT toolkit was run in debugging mode, in order to display the values on the PC screen and keep the NXT alive (Fig. 3). The frequency and the signal amplitude were gradually changed and the sensor readings were noted manually and entered into an Excel-file and also into a LabVIEW 3D-graph program (that we do not reproduce here). (Fig. 4 and 5) show the different graphs in 3D for the frequencies 100..1000Hz.

  •  
    many sample codes for different reasons
  •  
    they are good codes because we can use them to help the robot carry out specific functions. also they are much simpler than the long codes that we have to make so in the long run these codes will make it easier and it will save us time

Line Follower - LabVIEW for Lego MINDSTORMS Projects - 3 views

  • 3. In case the lighting in the room changes, could you program your line follower to re-calibrate the light sensor when you push a button?

      could b useful later on to look into
  •  
    Tufts University Center for Engineering Education and Outreach In this activity, we will learn how to create a robot that follows a line on the ground. It will use one light sensor to sense where the line is, and use this to control the motors to steer the car and stay on the line.

  • subset of the array the chart displays.
  •  
    Shows how datalogging works
  •  
    Use front panel datalogging to record data for use in other VIs and in reports. For example, you can log data from a graph and use that data in another graph in a separate VI. Each time a VI runs, front panel datalogging saves the front panel data to a separate datalog file, which is in the format of delimited text.

Using Shift Registers - 1 views

  •  
    LabVIEW 2009 LEGO MINDSTORMS NXT Module Help When using loops, it is often useful to have a result from the last iteration of the loop for the next iteration of the loop. This can be accomplished using Shift Registers; shift registers will pass values from previous iterations through the loop to the next iteration.

  • sounds like for your application you might want to use the Log Angle (red/blue/green) nodes to acquire your data. This lets you sample at a specific rate for a given amount of time and saves the data to a file called RedData.dat, BlueData.dat or GreenData.dat depending on the color of the Log Angle you chose
