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 ;-)
2009-09-04Fix race condition that caused commands such as stop_rx_streaming to fail.Eric Blossom
This fixes the bulk of the problem. Next step is to drop data packets while waiting for the reply.

2008-12-27Implements USRP2 peek() command, allowing arbitrary reads from the internaljcorgan
Wishbone bus. Minor fix for USRP2 sync_to_pps() (uses correct packet type.) Example: >>> from gnuradio import usrp2 >>> u = usrp2.source_32fc() >>> u.peek(0x1234, 4) # Read four bytes at offset 0x1234 (code) (185, 244, 253, 164) >>> The return value will be zero length upon error. The read address must be 32-bit aligned, and only the lower 16 bits are significant. The length must be an integral multiple of 4 bytes. There is currently a read limit of 176 bytes per read; to change requires some additional firmware changes to allocate a larger reply packet. WARNING: Trying to read from memory locations not serviced by RAM or by a Wishbone peripheral may result in a hang requiring a USRP2 power cycle. The USRP2 internal memory map is documented in usrp2/firmware/lib/memory_map.h. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@10172 221aa14e-8319-0410-a670-987f0aec2ac5

2008-09-08Merged r9433:9527 from features/gr-usrp2 into trunk. Adds usrp2 and ↵jcorgan
gr-usrp2 top-level components. Trunk passes distcheck with mb-gcc installed, but currently not without them. The key issue is that when mb-gcc is not installed, the build system skips over the usrp2/firmware directory, and the firmware include files don't get put into the dist tarball. But we can't do the usual DIST_SUBDIRS method as the firmware is a subpackage. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@9528 221aa14e-8319-0410-a670-987f0aec2ac5
