I need to create a triangular waves in NI USB 7856R. I am using the generates the sine waves but i am not sure what or how to do create a triangular waves

Right next to the Sine Waveform VI, there's a Triangle Waveform VI under the Waveform Generation palette.

You can refer to FPGA Sawtooth Wave Generator IP

thanks your reply ,but i dont find triangle wave generator VI . i use labview fpga and my board is NI USB 7856R

this is my fpga waveform Generation palette.

Hi, I guess you do not have a triangular waveform generator on FPGA palette. Therefore, there are at least two methods to generate triangular waveform.
If you would like to go with the option 1 above, the best example would be the one available with FlexRIO driver.
After installing FlexRIO driver (such as version 21.5), go to Example Finder >> Hadrdware Input and Output >> FlexRIO >> Integrated IO >> Getting Started >> Getting Started FlexRIO Integrated IO.vi.
After open the VI, select and press OK as shown below.
Then, learn what is implemented on FPGA as well as on host PC.
It takes some time to learn, but once you learn the example, you would get familiar with various concepts and components of LabVIEW FPGA. SubVIs included in this example are very reusable for R-series.
By the way, is this triangular waveform used for modulation or something?

thanks,i will try to learn how to use this.
yes i want to modulation a light.

Learning curve of LabVIEW FPGA is less steep than the other FPGA languages, though LabVIEW FPGA cannot directly exploits various sorts of primitives available on FPGA. I strongly recommend you to take LV FPGA training course and continue to the additional resources below.
