Integrating the driver in the <a class="ulink" href="http://www.comedi.org" target="_top"><acronym class="acronym">Comedi</acronym></a> library
</h3></div></div></div><p>
For integrating new drivers in the <a class="ulink" href="http://www.comedi.org" target="_top"><acronym class="acronym">Comedi</acronym></a>'s source tree the following
things have to be done:
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
Choose a sensible name for the source code file. Let's assume here
that you call it <span class="quote">“<span class="quote">mydriver.c</span>”</span>
</p></li><li class="listitem"><p>
Put your new driver into <code class="filename">comedi/drivers/mydriver.c</code>.
</p></li><li class="listitem"><p>
Edit <code class="filename">comedi/drivers/Makefile.am</code> and add <code class="literal">mydriver.ko</code>
to the <code class="literal">module_PROGRAMS</code> list. Also add a line
</p><pre class="programlisting">
mydriver_ko_SOURCES = mydriver.c
</pre><p>
in the alphabetically appropriate place.
</p></li><li class="listitem"><p>
Edit <code class="filename">comedi/drivers/Kbuild</code> and a line according to
the type of driver:
</p><pre class="programlisting">
obj-$(COMEDI_CONFIG_PCI_MODULES) += mydriver.o # for a PCI driver
</pre><p>
</p><pre class="programlisting">
obj-$(COMEDI_CONFIG_PCMCIA_MODULES) += mydriver.o # for a PCMCIA driver
</pre><p>
</p><pre class="programlisting">
obj-$(COMEDI_CONFIG_USB_MODULES) += mydriver.o # for a USB driver
</pre><p>
</p><pre class="programlisting">
obj-m += mydriver.o # for other driver types
</pre><p>
</p></li><li class="listitem"><p>
Run <span class="command"><strong>./autogen.sh</strong></span> in the top-level comedi directory. You will
need to have (a recent version of) autoconf and automake
installed to successfully run <span class="command"><strong>autogen.sh</strong></span>. Afterwards, your driver will
be built along with the rest of the drivers when you run <span class="command"><strong>make</strong></span>.
</p></li><li class="listitem"><p>
If you want to have your driver included in the <a class="ulink" href="http://www.comedi.org" target="_top"><acronym class="acronym">Comedi</acronym></a> distribution
(you <span class="emphasis"><em>definitely</em></span> want to :-) ) send it to
the <a class="ulink" href="http://www.comedi.org" target="_top"><acronym class="acronym">Comedi</acronym></a> mailing list
for review and integration. See the top-level <code class="filename">README</code>
for details of the <a class="ulink" href="http://www.comedi.org" target="_top"><acronym class="acronym">Comedi</acronym></a> mailing list.)
