Talking to the parrallel i/o ports

Talking to the parrallel i/o ports

[clark]

Hello everyone,

	I was wondering if any one has written a nice little utility to control
the parallel i/o ports of the MPC8xx. I was hoping to be able to call it
from other programs as well as manipulate the ports from the the command
prompt and scripts. I thought I would check to see if anybody has already
done it before I tried to do it my self.


	Many thanks in advance,

	Conn Clark

Hello Conn,

I wrote a nice little I/O control subsystem for the MPC850.  It is in
QSLinux (http://qslinux.org, ftp::/qslinux.org), and is in the
subdirectories snmc/qslinux/kernel and snmc/qspin.

The subsystem gives you the ability to check, request, and configure the
function of the I/O pins on the MPC850.  It is modeled after the I/O
address allocator for the 80x86 architecture.  You can access the
subsystem either from kernel space, or from a user space program.

You will need to modify the subsystem for operation with other MPC8xx
processor (i.e. the MPC860 has more I/O pins). But this should not be
difficult.

I don't have a command-line driven program that interfaces to the
subsystem, but if you write one and are willing to share it I would love
to have a copy :-).

Regards,
Daris

Hi Daris,

         I'm having a little trouble locating the source you were talking
about. I have tried looking at http://qslinux.org/snmc/qslinux/kernel  and
http://qslinux.org/snmc/qspin but they come up as 404 Not Found. I have
also looked at your ftp site under ftp://qslinux.org/snmc/qslinux/kernel
and ftp://qslinux.org/snmc/qspin with no luck. I was able to find
ftp://qslinux.org/pub/qslinux/ with complete source tar files. Do I have to
down load one of these?

         Thanks for the help.

         Conn

Conn,

Sorry for the confusion.  You will need to download the tarball for the
qslinux source, expand that out, and then look in the directories
snmc/qslinux/kernel and snmc/qspin.

You can download the latest kernel tarball from:

	ftp://qslinux.org/pub/qslinux/

Regards,
Daris
