[Discuss-gnuradio] Transmitting additional data from N210 to the PC

[Eral Tuerkyilmaz]

Hi,

I want to change my USRP N210 - FPGA config to calculate a correlation 
sum and transmit this sum synchronously with the I/Q sample pairs to the 
PC (e.g to get this samples from an extra channel on the UHD block). 
What would be the easiest way to transmit these additional data to the 
samples and where are changes necessary (firmware, fpga-config)?

Thanks,

Eral
