This is an example that allows capturing RF data into DRAM, and then
stream it back to host, using the Python API.

the USRP power meter will only receive from a single channel which
is configured by the argument parameter. The streamer receive
data will therefor alwalys have a single channel. So do not index
with chan when passing the streamer to uhd.dsp.signals.get_usrp_power.

- Like with RX, this now allows passing in stream time and existing
streamer
- There was no EOB being sent at the end (now there is)
- Fixed some linter issues

This fixes a subtle bug, where a variable to cache the timestamp of an
error gets bound to the metadata instead of creating a copy thereof.
Without this fix, the calculation of dropped samples would always be 0,
because the difference in timestamps would incorrectly be always zero.
This fix will now make a copy of the timestamp.
Shoutout to GitHub user bhorsfield for finding this issue.

The numbers for these were swapped.

This PR applies antenna channel settings before available calibration
data, and moves initialization code to setup_device, returning necessary
settings in a tuple.

This is a utility that can be used to measure received power, assuming
a calibrated device.
For example, it can be called like this:
usrp_power_meter.py -a type=x300 -f 1e9 --mode continuous
To continuously measure input power at 1 GHz.

This changes two things in all applicable files:
- Remove imports from __future__
- Change default shebangs from /usr/bin/env python to /usr/bin/env

This allows adding stream args to the Python version of benchmark_rate
in the same way as for the C++ version, e.g.:
python3 ./benchmark_rate.py \
--args addr=192.168.40.2,num_poll_offload_threads=4 \
--rx_stream_args \
recv_offload=1,num_recv_frames=32,recv_offload_wait_mode=poll \
--tx_stream_args \
send_offload=1,num_send_frames=32,send_offload_wait_mode=poll \
[... other arguments ...]

- When printing statistics, the number of TX and RX timeouts were mixed
up.
- Fixing main() docstring

Also updates our coding style file.
Ancient CMake versions required upper-case commands. Later command
names became case-insensitive. Now the preferred style is lower-case.
Run the following shell code (with GNU compliant sed):
cmake --help-command-list | grep -v "cmake version" | while read c; do
echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done > convert.sed \
&& git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' \
'*CMakeLists.txt' | xargs -0 gsed -i -f convert.sed && rm convert.sed
(Make sure the backslashes don't get mangled!)

Duration of multichannel benchmark was 50 seconds longer than
intended- a 50ms initialization delay was mistakenly multiplied by
1000.

- Separating exposed Python data structures into logical sections
- Exposes all of the multi_usrp API
- Adds a layer of Python for documentation and adding helper methods
- Adds improvements and fixes to the MultiUSRP object
- Includes additional exposed data structures (like time_spec_t, etc.)
- Add code to release the Python GIL during long C++ calls
|
|
|
Initial commit of the Python API using Boost.Python. Bind the
MultiUSRP API for use in Python. Bindings intended to provide as
complete coverage as possible.
- Wrap most multi_usrp calls
- Adding multi channel send/recv examples in examples/python
- Adding setuptools support
- Initial attempt at binding the UHD types and filters
