[Discuss-gnuradio] controlling Digital I/O from GRC

[Lapointe, Benjamin - 1008 - MITLL]

Hi,

 

I would like to control the digital I/O (8 of the lines) of the USRP X300 from GNU Radio Companion.  Has anyone attempted this?

 

From reading the gpio_api online, it sounds like I need to discover the digital I/O by using the get_gpio_banks function in multi_usrp, and then use usrp_x300->set_gpio_attr() to control the digital I/O.  Is there a way to do this from GNU Radio Companion?  My experience thus far has been dragging and dropping blocks in GRC.  If I make a block from scratch, I am assuming I will need to pass the usrp_x300 handle into the block to make the calls (I don’t have experience making my own GRC blocks).  I would also need a user interface to assign the value for the output of the digital I/O.

 

Any recommendations on where to begin?

 

Thanks!

-Ben
