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
