The commit provides a basic implementation of support for LimeSDR USB
receivers based on LMS7002 chip. The solution has several limitations:
- passing parameters for tune LimeSDR receiver via command-line
options is not implemented;
- only hardcoded configuration is used (channel 0 of lower band LNA,
LMS_FMT_I16 format, gain, bandwidth and timeout);
- only one device is supported and it is not possible to select a
desired one in case if several devices are connected to the host.
Test: compare the output of the program for RTL and LimeSDR receivers.
Environment:
- RTL2832SDR dongle;
- LMS7002M based USB LimeSDR board;
- 800MHz-2200MHz omnidirectional antenna with SMA connector.
Procedure:
- connect RTL dongle to the host and start the program with the
following parameters:
$ ./dump1090 --device-type rtlsdr --interactive
- wait until several planes will be detected;
- stop the program, connect the LimeSDR board to the host and restart
the program with the following parameters:
$ ./dump1090 --device-type limesdr --interactive
- ensure that the same planes are detected.
Acceptance criteria: the same planes are detected using both receivers
and track information matches with information from the
FlightRadar24 application.
