Create a Custom Waveform with USB-845x

Hardware

  • USB-8451
  • USB-8452

Driver

  • NI-845x

Issue Details

I have a device that expects to receive a custom waveform sent over the SPI bus. How can I do this with the USB-8451 or USB-8452?

Solution

The Scripting API is designed to send custom waveforms on the SPI bus. It gives more complete control over each line on the bus and can be used to construct custom waveform signals.

Additional Information

For more reference on the Scripting API, please see the NI-845x Hardware and Software Manual. There are also examples located in the LabVIEW Example Finder in LabVIEW Help » Find Examples » Hardware Input and Output » I2C and SPI » SPI Scripting.
