Hello everyone,
I have implemented SocketCAN wrappers for FreePascal which I would like to
contribute. Before creating a patch for Mantis, could
someone please take a look at it's current form and advise me on further steps,
changes and improvements that I should
eventually do? I would like it to be available right out of the box with
FreePascal (as it is now the case with Python and C),
so I guess that it should end up as a FreePascal package.
Maybe it is important to mention that SocketCAN is linux only, but seeing how
popular it is I do not think it will stay that for
long.
I have already prepared sockets for CAN changes earlier with this patch:
https://bugs.freepascal.org/view.php?id=38566.
There is still some work waiting for me with SAE J1939 high level protocol and
writing docs and more demos, but I would
appreciate if you could take a look at it's current state and give comments.
Just download can.zip file from this message:
https://forum.lazarus.freepascal.org/index.php/topic,39858.msg397239.html#msg397239.
I had a look.
Since this is currently linux-only, and there are several units, I would opt to
make this a separate
package.
The directory structure to use should be clear, I suppose:
can
can/src
can/examples
Is there any reason you used mode Delphi ? If possible, I would prefer it if
you used mode objfpc. It's a little more strict than Delphi mode.
If you can make a fpmake.pp file, that would be appreciated, but if you
don't feel up to that I can do it when you submit the sources, that's not a
problem.
Michael.
