![]() The Digilent WaveForms VIs will throw an error if Digilent WaveForms is still open when you run your code. Note: Before testing or running your LabVIEW code, make sure that WaveForms is not opened. For more information on getting started in LabVIEW, including the installation of the Digilent WaveForms VIs, please view the resources available here: Getting Started with LabVIEW and a Test and Measurement Device. ![]() This section of the lab will assume a working knowledge of the LabVIEW environment and basic programming conventions. We will then look at baud rates and the start and stop bits and compare the binary output with the signal we sent with the help of the microcontroller. ![]() In order to receive the signal, we will first acquire the signal using the digital capabilities of the Mixed Signal Oscilloscope on the Analog Discovery Studio and then use software controls to set an appropriate sample rate. By taking advantage of LabVIEW’s ability to visualize data, we can see how each step in this process is accomplished. We will be doing this by sampling the signal using the Analog Discovery studio and displaying it in LabVIEW. One way to take those signals and recover the original message signal is to acquire the signal with the Logic Analyzer from the Analog Discovery Studio in LabVIEW. Follow the steps below to output a serial signal. This lab uses the Arduino UNO microcontroller, but the exact same code can be used with a chipKIT or other similar microcontroller. Now we will go ahead and experiment with sending and receiving signals using a microcontroller and Analog Discovery Studio. ![]() USB Scopes, Analyzers and Signal Generators. ![]()
