I wrote gr-cxadc which is a gnuradio wrapper to use the cxadc driver from any gnuradio script, just like the gr-usrp does for the usrp. So you don't need to capture to file first anymore. I also wrote some example scripts which work fine (including GUI). I haven't implemented tuning yet, because we need a mor general approach for the different tuners out-there. (Maybe use the way this is done in v4l drivers) For now I just hooked the IF-output of my TVRX to the video-input of the cx2388xx TV-tuner card. (I then can tune the TVRX tuner using the usrp, but all the capturing is done using the tv-card / cxadc) You can find the files at: http://www.olifantasia.com/projects/gnuradio/mdvh/cx2388x/cxadc/ cxadc_examples.tar.gz example scripts (copied from usrp examples and modified to work with gr-cxadc) cx2388x_oscope.py cxadc_fft.py cxadc_rx_cfile.py cxadc_wfm_rcv.py cxadc_wfm_rcv_nogui.py cxadc_v3.tar.gz The kernel driver written by Hew How Chee gr-cxadc-0.1cvs.tar.gz The gnuradio code to use it from gnuradio I also added it all to my section of the svn repository at: http://gnuradio.org/trac/browser/gnuradio/branches/developers/nldudok1/general-wip Make sure you read cxadc_v3/readme and the page by Hew How Chee at http://www.geocities.com/how_chee/cx23881fc6.htm Greetings, Martin > > A GNU Radio Python FM demodulation code is provided > also to see how the ADC samples are converted and > processed offline. > > Regards, > Hew > p/s : the site might become unavailable due to > bandwidth limit. > > > > > ____________________________________________________________________________________ > 8:00? 8:25? 8:40?
