Here is a non-exhaustive list of things IMO to keep in mind while
|
|
developping the Hamlib library.
|
|
|
|
|
|
Plan:
|
|
----
|
|
o Hamlib is intended to provide the means to control any capable rig
|
|
o develop the library as a shared/static library
|
|
o portable (not only Linux, but UN*X, Win32 using cygwin, etc. -> autoconf?)
|
|
o be good, be generic (any rig made, any model)
|
|
o uniform data types/units (eg. for power, use Watts, not rig specific val)
|
|
o wrappable (Java, C++, perl module, Python module, etc.)
|
|
o support serial ports, IrDA ports, USB ports, network ports (w/ a daemon)
|
|
o thread safe (reentrant) would be a must
|
|
o support preference file (eg. /etc/hamlibrc, ~/.hamlibrc )
|
|
o written in C (C++ would have been much more appropriate, but C is okay)
|
|
o support more than one rig per application (ie. generic code)
|
|
o support more than one rig per serial port (ie. Icoms)
|
|
o handle nicely serial retransmission and timeouts
|
|
o i18n support if applicable
|
|
o software compensation for the actual radio oscillator frequency errors(mode?)
|
|
o if avail., support events sent by the rig (eg. main freq has been changed,..)
|
|
o maybe add some misc functions like PTT signaling (through serial/parallel..)
|
|
o Well documented API, and Howto write a new rig backend
|
|
o ...
|
|
|
|
|
|
Good inspiration:
|
|
----------------
|
|
o SANE, with frontend/backend scheme, dynamic loading, autoconf, etc.
|
|
o struct net_device (Linux kernel) for the "void *priv" idea
|
|
o any rigctrl sources out there ?
|
|
|
|
|
|
Applications:
|
|
------------
|
|
o control your rig from your computer, can be handy if you've relocated
|
|
your UHF transceiver in the attic, to reduce cable loss.
|
|
o edit/backup/restore/extend the memory capacity of your rig
|
|
o software scanning (and huristics)
|
|
o s/w squelch
|
|
o real time spectral analysis and digital modes ( Frank has written some
|
|
working code for this) it does 40 frames / sec and no load,
|
|
really cool to see time and spectral info !!
|
|
He has based it on generic data engine and plugins !! output also to
|
|
small gtk window.
|
|
o doppler compensation in tracking mode (using mtrack satellite tracker?)
|
|
o let real time signal analysis drive freq/modes/etc.... (eg. PSK31 tuning)
|
|
o networked rigs, provides realtime (global) spectral analysis to
|
|
find (a common) quiet part of the band for a qso between 2 parties
|
|
o software controlled hopping (poor mans GSM frequency hopping)
|
|
also, must output hopping sequence to other rig to be useful
|
|
o computer assisted scanner
|
|
o <add here the application you thought it'd be impossible>
|
|
|
|
|
|
Capabilities:
|
|
------------
|
|
We have to find a way to code capabilities in the hamlib in order
|
|
to let the application know what this rig is able to do (before
|
|
attempting to do it and crash :).
|
|
I think some features can be coded using bit fields and masking.
|
|
|
|
Maybe we can distinguish between 3 states :
|
|
- Don't have this feature,
|
|
- Have it,
|
|
- Have it and can control (r/w) it remotly using the backend in hamlib
|
|
|
|
o freq ranges supported: rx/mode, tx/modes/power
|
|
o number of VFO, operations (set VFO separately, VFO A=B, switch, ..)
|
|
o freq granularity, tuning steps (-> array)
|
|
o SCAN functions (start, stop, ..)
|
|
o Split (cross band, duplex, ...)
|
|
o RIT (+- KHz)
|
|
o Memory scheme, what is stored in, quantity, call channels, scan edges
|
|
o ATT, P.AMP, AGC, NB, TONE, TSQL, COMP, VOX, BK-IN, ...
|
|
o Tuner control (internal, external, can control)
|
|
o Meter indication: Squelch condition, S-meter level, ALC, SWR
|
|
o Number of antennas (which band ?) and selection
|
|
o available "set mode" items (ie. rig setup), and provide a way to modify them
|
|
o DSP ?
|
|
|
|
o max memory channel
|
|
o per rig timeout/retry (can be overriden)
|
|
o Write some memory channel handling (name, mode, freq/vfo, duplex, split, ..)
|
|
|
|
Any other ideas?
