[Discuss-gnuradio] Error building gnuradio on USRP E100

In response to Josh's announcement I have grabbed the latest git of UHD and GNURADIO and tried to build it on my E100. I followed the instructions from the usrpe1xx-FAQ. UHD built and installed okay but GNURADIO fails with the following errors: Is this a case of the UHD from git://ettus.source

[Discuss-gnuradio] gr_shared_ptr.i vs boost_shared_ptr.i

Hi all, I've been trying every now again to create classes in gnuradio that are not signal processing blocks but are wrapped up in the same way used boost::shared_ptr and SWIG. I haven't been able to replicate how it's done for the signal processing blocks. I have been able to get the same thing

Re: [Discuss-gnuradio] Where can I find C++ source code of an API

The basic idea in gnuradio is that you're stringing signal processing blocks together. There's some scheduling going to work out when different blocks are doing number crunching which I know nothing about. Each block has a "work" or a "general_work" function that is called by the scheduler (I thi

[Discuss-gnuradio] what the relation between the amplitude set in program and voltage of the received signal

Dear all, I'm using USRP1 with LFRX plug-in. Could you please tell me what's the relation between the amplitude that we set in program and the voltage of the received signal. For instance, if I receive a signal whose amplitude read from the received data file is 2000 units, what's the correspon

Hi, Ben, >From line 59 of gr_probe_avg_mag_sqrd_c.cc, mag_sqrd is the "input" variable. mag_sqrd comes from pointer in at line 58. Pointer in comes from pointer input_item at line 55. I know &input_item is a parameter of function work at line 52. My question is that where will work function be cal

Re: [Discuss-gnuradio] Where can I find C++ source code of an API
