I updated the wiki paged and added state machines. (http://gnuradio.org/trac/wiki/UsrpTxModifications) Here are the issues still unresolved that I am aware of: - Are the overrun/underrun flag per channel or global? From which fifo should they be generated? - When a packet is outdated I still

Hi guys It appears that the pdf/ps schematics located at: http://gnuradio.org/svn/usrp-hw/trunk/USRP_REV_4_2/ are incomplete or cropped. I thought it might be my version of Acrobat Pro but I updated it and still unable to see the full page. Could someone have a quick check to make sure its no

Hello, Yet another project I am interested in. Number 157 on the list. 8) ADS-B is an interesting system that allows aircraft to send position and other information. It uses the 1090 MHz Transponder frequency. http://www.garmin.com/aviation/adsb.html ADS-B is more progressed over in Europe. I

Dear all, there has been a list of questions that have been puzzling me 1) Can we access the memory of the FPGA on the usrp and store on it data? If yes does that mean that i can use the usrp without having to connect it to a PC? 2) what are those pins on the USRP (can they be used to connect

[Discuss-gnuradio] Block processing and printing results in python

2007-03-24 Thread Robert Miller
Hello, I would like to repeatedly compute signal characteristics for consecutive blocks of data from the USRP, while echoing the results to the screen (e.g. mean,etc.). I would prefer to do this within python without writing my own signal processing block. Is this possible without writing my ow
