Re: [Discuss-gnuradio] B200/mini GPIO

[Santos Campos]

Hello again again!

So I'm trying to write an OOT module to control the gpio from GRC.

Would I have to create a usrp device in the module's code if I am using a usrp source?

My gut says to probably not re-declare it since it's already in use, but I'm not sure how I could bring it into scope if I don't have to re-declare it.

I tried poking around for the usrp sink code to see what it did but couldn't find it.

Worked like a charm! Thanks for the helpful comments!

Like I said originally, I'm trying to use the gpio to remotely switch between 2 antennas.

Currently trying to familiarize myself with boost and the uhd api. Will undoubtedly be back to the listserv with questions on those.

Hello again, all! I've finally come back to this after a while.

I'm trying to get the example code to compile but having some trouble. Does anyone have any experience with using the uhd gpio api?

I tried using this to compile:

    $ gcc -I/usr/include/boost -I/home/santosec/uhd/host/include/uhd gpio.cpp -o gpio

but I got a whole mess of compiler errors.

And, to follow-up with details:

Hello! I am curious if it is possible to use a pin or something on either the B200 or B200 mini to send a control signal.

We were hoping to be able to switch between 2 antennas if the board received some signal. It looks like there could be some available pins, but we were unsure if they would be able to fulfill our purpose. If not, any ideas around this issue would be welcome!

Any help would be much appreciated!

The API for the B2xx GPIO is the same as for X3xx.

There's example code:

.../uhd/examples/gpio.cpp
