[ts-7000] TS7500 DIO control while user is not root

["frankvd99" <>]

Hello,

I have a TS7500 board and trying to control the digital IO lines from 
Debian-linux on the sd-card.

When running the script below as user "root" it works fine. When doing the same 
thing as user eclipse (or any other user) I get below message.


#!/bin/sh
. /initrd/ts7500.subr
#
echo "IO value of pin 5:"
getdiopin 5
#

Response when user root:
IO value of pin 5:
1

Response when user eclipse:
ts7500ctl: ts7500ctl.c: 771 main: Assertion 'dev/mem !=-1' failed

I've traced this back to the ts7500ctl.c file which is trying to open /dev/mem, 
which is not allowed.

Is there another way how I can get this done. My goal is to run TS7500 digital 
IO control from a CGI script in the Apache webserver. Apache does not allow you 
to run it as root, so that is not a workaround.

Thanks for your help
Frank
