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.
