The purpose of this project is to provide stable, flexible, shared libraries that enable quicker development of amateur radio equipment control applications.
The master repository is https://github.com/Hamlib/Hamlib
The backup repository is https://sourceforge.net/projects/hamlib/
Daily snapshots of the master branch are available at https://hamlib.sourceforge.net/snapshots/
Daily snapshots of the Hamlib-4.7 branch are available at https://github.com/Hamlib/Hamlib/tree/Hamlib-4.7
Note: Major changes are planned for Hamlib 5 (current master branch) which will introduce incompatibilities with existing software that uses Hamlib. Until a given software application announces support for Hamlib 5, use the snapshots and releases from the Hamlib-4.7 branch.
Development happens on the GitHub master (often by merging feature branches) and each release has a release branch.
Many amateur radio transceivers come with serial (RS-232, USB, etc.) or Ethernet/WiFi/Bluetooth interfaces that allow software to control the radio. This project will endeavour to provide shared libraries that greatly simplify the application programmer's interaction with radio equipment and other controllable devices such as rotators, amplifiers, etc.
The Hamlib Wiki page, Supported Radios, contains a snapshot of the supported radios at the time of the last Hamlib release. Go to https://github.com/Hamlib/Hamlib/wiki to reach the Wiki.
The library provides functions for radio, rotator and amplifier control, and data retrieval for supported devices. A number of functions useful for calculating distance and bearing and grid square conversion are included.
libhamlib.so - library that provides generic API for all RIG types. This is what application programs will "see". Will have different names on other platforms, e.g. libhamlib-4.dll on MS windows. Also contains all radio, rotator and amplifier "backends" provided by Hamlib.
-
yaesuwill provide connectivity to Yaesu FT 747GX Transceiver, FT 847 "Earth Station", etc. via a unified API. -
xxxxwill provide connectivity to the Wiz-bang moon-melter 101A (yikes..)
Hamlib will also enable developers to develop professional looking GUI's towards a unified control library API, and they will not have to worry about the underlying connection towards physical hardware.
Initially serial (RS232) connectivity will be handled, but we expect that IP (and other) connectivity will follow afterwards. Connection via a USB port is accomplished via the Linux kernel support. USB to serial converters are well supported. Other such devices may be supported as long as they present a serial (RS-232) interface to Hamlib.
Most distributions have the latest Hamlib release in their testing or alpha versions of their distribution. Check your package manager for the Hamlib version included in your distribution.
API documentation is at:
https://github.com/Hamlib/Hamlib/wiki/Documentation
Take a look at tests/README for more info on simple programming examples and test programs.
C++ programming is supported and language bindings are available for Perl, Python, and TCL. A network daemon utility is also available for any programming language that supports network sockets (even netcat!).
Hamlib is entirely developed using GNU tools, on various operating systems. The library may be compiled from a source "tarball" by the familiar "three step":
./configure
make
sudo make install
For debugging use this configure command:
./configure CFLAGS=-g -O0 -fPIC --no-create --no-recursion
See the INSTALL file for more information.
To recompile Hamlib, run:
make clean
to remove all object files and binaries, otherwise make won't do anything!
Consult the README.betatester and README.developer files in this directory
if you feel like testing or helping with Hamlib development.
Contributions of rig specifications and protocol documentation are highly encouraged. Do keep in mind that in some cases the manufacturer may not provide complete control information or it is only available under a Non-Disclosure Agreement (NDA). Any documentation must be publicly available so we can legally write and distribute Free Software supporting a given device.
The Hamlib team is very interested to hear from you, how Hamlib builds and works on your system, especially on non-Linux system or non-PC systems. We try to make Hamlib as portable as possible.
Please report in case of problems at [email protected] Git email formatted patches or in unified diff format are welcome!
Also, take a look at http://sourceforge.net/projects/hamlib/ Here you will find a mail list, link to the Wiki, and the latest releases. Feedback, questions, etc. about Hamlib are very welcome at the mail list:
Like other software projects, Hamlib uses a version numbering scheme to help program authors and users understand which releases are compatible and which are not. Hamlib releases now follow the format of:
Major.minor.point
Where
Major: Currently at 4, but can be advanced when changes to the API require
client programs to be rewritten to take advantage of new features of Hamlib.
This number has advanced several times throughout the life of Hamlib.
Advancement of the major number signals frontend API changes that require
modification of client source and Application Binary Interface changes that
require relinking to the library (Note, the latter does not apply to
applications using the *ctld daemons, but the command API may change).
Minor: This number advances when either new backend(s) or new rig model(s) to existing backend(s) are added. Advancing this number informs client program authors (and users of those programs) that new model/backend support has been added. Will also include bug fixes since the last point release.
Point: Formerly could be undefined (e.g. Hamlib 4.6) and would advance to 1
(e.g. Hamlib 4.6.1) for any bug fixes or feature additions to existing
model(s) or backend(s), then to 2, etc. New rig models or backends are not
included in point releases. When major or minor is advanced, point will
reset to 0. Note: All future releases beginning with 4.7.0 will include
all values to lessen confusion.
Hamlib has a "ready when it's ready" philosophy. There is no set schedule, though we'd like at least one minor release in a given year and a major release every several years.
