Working with the Labview portion of the lab required the configuration of analog inputs along with both analog and digital outputs. A couple pictures along with videos are located below serving as simple examples to our accomlishments with the Labview interface.
The figure directly below exemplifies three important concepts. Using the DAQ Assistant block in Labview, analog I/O along with digital output was configured. Refering to the figure, the bottom lop represents analog input to the NI-PCI-6230. A wave from was generated to verify the functionality of the analog input. The while loop in the upper left corner of the figure indicates the setup used to control digital output with the flip of a toggle switch in Labviews virtual interface. The while loop in the upper right corner of the figure indicates analog output from Labview. In this instance we simply generated a sine wave to verify functionality of the analog output DAQ Assistant.
The front panel of labview is shown below. The generated sine wave can be seen, and it's characteristics such as frequency and amplitude can be controlled by the user. The toggle switch controls the on/off capability of the digital output. A blinking LED in the video below shows the user toggling the switch back and fourth controlling the LED to turn off and on.
In the video below labview was programmed to output an analog signal which the team used to power a speaker.
Analog signals from the potentiometer and photo cell were also input into Labview to gain an additional understanding of how to control analog inputs.
