Comedi is a collection of drivers for data acquisition hardware. These drivers work with Linux, and also with Linux combined with the real-time extensions RTAI and RTLinux. The Comedi core, which ties all the driver together, allows applications to be written that are completely hardware independent.
Comedi supports a variety of data acquisition hardware; an incomplete list may be found at http://www.comedi.org/hardware.html#hw-comedi-org.
This distribution contains just the Comedi kernel modules. You will almost certainly also want to download Comedilib, which is a user space library, a few utilities, and some example programs.
For installation instructions, look at the file INSTALL.
Questions about Comedi should be sent to the Comedi mailing list, comedi_list@googlegroups.com. It is necessary to join the group before posting (see below). It is also possible to post to the list using the web interface (see below). Mailing the maintainer directly is always acceptable, but since the mailing list is archived and questions are often answered more quickly by others, the mailing list is preferred.
To subscribe to and unsubscribe from the mailing list, or to read or post messages via the web interface, go to http://groups.google.com/group/comedi_list. Alternatively, you can send a blank email to comedi_list+subscribe@googlegroups.com to subscribe, or to comedi_list+unsubscribe@googlegroups.com to unsubscribe (making sure the "From:" email address matches the address you originally subscribed with!).
Traffic on the list is light, and mainly questions/answers about comedi installation, bugs, and programming. General questions about data acquisition are also welcome.
Comedi also has a web page at http://www.comedi.org/ from where updated versions may be downloaded.
Often bugfixes and new features that are not in the current release can be found in the Git repository. Git snapshots can be created automatically at https://github.com/Linux-Comedi/comedi/tarball/master. The Git repository can be accessed anonymously using:
git clone https://github.com/Linux-Comedi/comedi.git
The Git repository was previously hosted at comedi.org. A previously cloned repository may need its URL updating to the current repository on github.com as follows:
cd /path/to/comedi
git remote set-url origin https://github.com/Linux-Comedi/comedi.git
Comedi may be freely distributed and modified in accordance with the GNU General Public License.
