Have somebody try to implement in LabVIEW FPGA a logic analyzer?

[xenopol]

Hy,

I want to implement in LabVIEW a logic analyzer/ digitizer using NI PXI as hardware. Have somebody try to do this or have an example? I will appreciate any opinion or support.

Thanks !

xenopol,

Do you currently have PXI hardware that you're trying to implement your logic analyzer/digitizer appliction with or are you looking for PXI hardware suggestions?

There is a helpful shipping example called "Logic Analyzer.vi" that comes packaged with the NI-HSDIO driver.  You can locate this in Example Finder (Help > Find Examples).

I have the PXI hardware and I try to implement a logic analyzer... I also have LabVIEW2010 software...I search for the example that you suggest me but I don't find it in LabVIEW2010...I would appreciate if you post the example here.

Thanks !

xenopol,

Can you provide me with the model number(s) of the PXI modules that you're working with?  There is a wide variety of modules available and I'd like to make sure that the one you're using is appropriate for this application.  Thanks!

I work with NI PXI-1042...and the module PXI that I use to acquire digital data is NI PXI-7811R Reconfigurable I/O.

I want to read digital data from Serial and I2C transmission...

Terminolgy may be getting in your way.

A logic analyzer will generally monitor multiple digtial lines at the same time ... like a 32 channel oscilloscope.

A Protocol Analyzer on the other hand will monitor a data line and interpret the data as bits sent one after the other.

I understand...I wanna implement a logic analyzer to monitor multiple lines...and I wanna test it to some circuit which comunicate Serial and I2C..

There are examples for I2C on our website.  As far as serial, that depends on what type of serial you are talking about.  I would still look on our IP network to see if the examples there serve your purpose.  The website is ni.com/ipnet

Let us know if this is helpful.
