GPIO for ettus N210

[lgl7tj]

Alas, the fields are greyed out for me as well. But I changed the name as the post above called for and inserted it into labview and something started working.

Here's a screen shot. Also, how do I toggle the GPIO pins on the board? Have you guys done that yet?

Hi bobbob1,

LabVIEW does not allow you to program the GPIO pins on the N210 or any other model of USRP.

Still waiting to hear back.
Need to access the GPIO pins for USRP B210. If the communications software won't do it, will LABVIEW fpga do it?

Are you guys using LABVIEW FPGA to compile B210's load  or are you using ISE14.7? 

I found an article on your website titled

What Xilinx FPGA Chips Are Used by National Instruments RIO Devices?

CompactRIO 9082

Spartan 6, LX 150

this is the fpga on the b210. 
Spartan 6 XC6SLX150 FPGA 

 I downloaded Labview FPGA and am going through the steps, please advise.

The 290x/B2x0 are not supported as LV FPGA targets.

For accessing the GPIO there is a VI which is not on the palette

niUSRP Set GPIO Attribute.vi

I haven't tested it but this thread looks helpful for determining required inputs to the VI:

trying to deciper that thread showing config parameters for the gpio vi. Can't find a reference sheet that explains the different commands. can't find anything on the ettus side either. 

National Instruments ?

update:

virtual void gr::uhd::usrp_block::set_gpio_attr ( const std::string &  bank,     const std::string &  attr,     const boost::uint32_t  value,     const boost::uint32_t  mask = 0xffffffff,     const size_t  mboard = 0    )

pure virtual

Set a GPIO attribute on a particular GPIO bank. Possible attribute names:

• CTRL - 1 for ATR mode 0 for GPIO mode
• DDR - 1 for output 0 for input
• OUT - GPIO output level (not ATR mode)
• ATR_0X - ATR idle state
• ATR_RX - ATR receive only state
• ATR_TX - ATR transmit only state
• ATR_XX - ATR full duplex state

  Parameters

  bank	the name of a GPIO bank
  attr	the name of a GPIO attribute
  value	the new value for this GPIO bank
  mask	the bit mask to effect which pins are changed
  mboard	the motherboard index 0 to M-1

  still treking forward will update if I figure something out

RDFer is a student of mine in the capstone program at the University of Virginia ECE department, he came to me for help today and here is the working solution we came up with:

the USRP attr wrap VI looks like this:

The commands that we used can be found in the GNU Radio Manual here (API for UHD):

Hi.
I realized that labvew supports B210 unofficially. But does B210 and GPSDO work with labvew? Has anyone tried it?

Hi,

We bought the SDR USRP b200mini of Ettus
https://www.ettus.com/product/details/USRP-B200mini

is this hardware compatible with LabVIEW?

It should work, but the USB driver won't load by default like it will with a NI product. Once you get the driver setup, you shouldn't have any problems getting it to run with LabVIEW.
