2009-09-04Merge branch 'new_eth' of http://gnuradio.org/git/matt into new_ethEric Blossom
* 'new_eth' of http://gnuradio.org/git/matt: properly set the address filter stop sending short ethernet command packets. Fix problem with commands timing out (specifically stop_rx_streaming) Fix race condition that caused commands such as stop_rx_streaming to fail. Fixing a line in the clock recovery algorithm. This works with a bit larger error than there proably should be. Better fix for broken AC_PROG_F77 macro Fix Python header check failure due to invalid cached state waterfall and fft use a common autoscale function Fix so that the waterfall texture is initialized with a buffer of the same size. Modifications to usrp2 source and sink so that set center freq is called afer set lo offset. Modifications to the usrp blocks and wrapper so that the lo offset is set with the lo frequency. Removed subversion related configuration info. Expand frequency ranges to match hardware capability. Modified log power fft block so ref scale is peak to peak. Adding clock sync algorithm using PFB. This works, but needs a bit more work.

2009-09-04Fix problem with commands timing out (specifically stop_rx_streaming)Eric Blossom
After fixing the race, this change uses Tom's idea to stop enqueuing data when trying to stop, and adds a new flush_rx_samples method to drop any samples that may have already been accumulated. I ran Tom's test case 500 times with 0 failures ;-)

This fixes the bulk of the problem. Next step is to drop data packets while waiting for the reply.

2009-08-02Made libusrp2 min and max samples even number.jcorgan
This forces an even number of samples in the min or max case, preserving the alignment of interleaved samples in the face of RX overruns or TX underruns. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11526 221aa14e-8319-0410-a670-987f0aec2ac5
2009-07-30Add custom FPGA build.jcorgan
This is a custom build for USRP2 FPGA. It allows using a BasicRX or LFRX board and feed two independent, real signals. In addition, instead of the CIC/HB decimator, which optimizes frequency response, it uses an integrate and dump decimator, which optimizes for time-domain impulse response. These changes have been made in dsp_core_rx.v: * A second DDC has been added, sharing a frequency register with the existing DDC. * The output of the two DDCs are interleaved as I1 Q1 I2 Q2I ... into the receive FIFO. This limits the host configured decimation to 8 intead of 4. Use gr.deinterleave to recover the streams. * The ADCs are hardcoded: RX_A ==> DDC #1 I-input 0 ==> DDC #1 Q-input RX_B ==> DDC #2 I-input 0 ==> DDC #2 Q-input Thus, the input mux has been disabled. * The CIC/HB decimator has been replaced by an integrate and dump at the decimation rate. * To assist with meeting timing, the external RAM has been disabled. The basic application is to coherently sample two real IF streams and downconvert to baseband, while minimizing the impulse response duration of the resampling filters. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11519 221aa14e-8319-0410-a670-987f0aec2ac5
