9b17824c49 Big update to UHD 3.14, Gnuradio 3.8, Python 3.6. Not fully tested. 2019-09-17 14:13:51 -07:00

514414f6b3 Fix integer truncation issue in tag_to_timestamp(). Thanks to John Ilig 
for finding it.

2c9ef501b8 Correctly use zero offset for devices that don't issue proper timestamp 
tags.

953a7ddded Correctly return a zero timestamp tag instead of a null tag. 2015-07-09 13:03:10 -07:00

c96dea7fa0 preamble: Check to see if PMT key is actually a symbol before converting 
to string.

9bdac2a499 Use whole/fractional timestamps in the whole chain. This prevents loss 
of precision when setting time to UTC.

b7627fa2d4 Rewrite CRC to use bytewise CRC instead of bitwise. ~8x faster. 2013-08-19 16:40:02 -07:00

a528f375f7 Huge messy reorg to move things into the GR3.7 paradigm. Mostly in effort to get 
SWIG magic to work on member functions. Can change sample rate on the fly now.

1630e67c3b Preamble subtracts average (LPF'ed) input from samples. This has the effect only 
of improving the slicer threshold to exactly 0.5.

0ce6374656 Convert next branch to 3.7 API. Based on Johnathan Corgan's 3.7 conversion of 
the master branch.

7dba7f4cc3 Add support for type 16 Long Special Surveillance packets. Not tested with real data. 2012-10-17 18:28:39 -07:00

5f89eba234 Fixed TCAS packet reporting -- the slicer wasn't reporting long pkt type for types 20/21. Hardcoded constant. 2012-10-17 18:01:02 -07:00

85da74b43a Fix preamble/slicer dB numbers. Was using power ratios for voltages (2.0 instead of 1.414 for 3dB, etc.). No real performance change. 
Fix suggested by Denis Gapotchenko.

8939a72e62 Preamble was sometimes consuming more samples than it was given, due to rounding issues and due to the early/late gate peak detector. 2012-09-14 09:41:21 -07:00

6c7a73702e Slicer was being called with fewer samples than necessary for output. This may fix the "O" bug and should reduce CPU consumption. 2012-08-23 09:05:18 -07:00

17b788efc7 Possible fix for the hang bug -- preamble could under certain circumstances consume -1, which makes Gnuradio think we're done. 2012-08-14 09:27:34 -07:00

17f7cb9a53 Backport Flightgear server from private tx branch, collapse commits. 
* Added Flightgear multiplayer output interface to uhd_modes.py. This allows flight with live traffic in fgfs.
* Quaternion library borrowed from PyPi and modified to generate angle/axis representation and construct rotation quat from lat/lon to ECEF.
* Miscellaneous enhancements and cleanup to fix timestamps, add aircraft type field (seems to be unused anyway), turnrate info

8522bc0b25 CMakeified almost everything. Test code in python/ and apps other than uhd_modes.py still need minor updating. 2011-12-14 10:17:16 -08:00
