It is Funcube Dongle Pro Plus server for ghpsdr3-alex implementation on python.
Dependencies is:
- python-alsaaudio
- python-numpy
- https://github.com/bazuchan/cython-hidapi (fork of https://github.com/gbishop/cython-hidapi)
Todo:
- support for multiple receivers (it's incomplete).
Basic usage:
- run fcdpp-server.py
- run dspserver
- run QtRadio
Usage: fcdpp-server.py [-h] [-s] [-p] [-l] [-m] [-i IF_GAIN] [-o PPM_OFFSET] [-a IPADDR]
fcdpp-server.py
optional arguments:
- -h, --help show this help message and exit
- -s, --swapiq Swap the I and Q inputs, reversing the spectrum
- -p, --predsp Offload some processing to an instance of predsp.py
- -l, --lna_gain Enable the LNA gain.
- -m, --mixer_gain Enable the mixer gain.
- -i IF_GAIN, --if_gain IF_GAIN Specify the IF gain in dB as integer, default 0.
- -o PPM_OFFSET, --ppm_offset PPM_OFFSET Frequency offset in parts per million, as float i.e. 3.9
- -a IPADDR, --ipaddr IPADDR The server's IPv4 address to bind to. Default is all addresses, i.e. 0.0.0.0 (alias addresses can be used)
Predsp: If you want to run fcdpp-server.py on embedded hardware (like BeagleBone Black in my case), you probably would want to move all data preprocessing (eg. conversion from ints to floats) to host running dspserver. For that purpouse I wrote small script called predsp.py. Usage:
- on embedded host run 'fcdpp-server.py -p'
- on more capable host run 'predsp.py' and 'dspserver --server '
- run QtRadio or another client and point it to dspserver's address
