Hi all,
I am using a linux 2.4.18 kernel patched wiht rtai-24.1.10 and a recent
cvs snapshot of comedi
and comedilib.
I've managed to run the rtai examples, and the comedi examples and I've
been able to "talk"
with the digital io on my ni6036e daq board.
The mail list archive makes mention of real time examples packaged with
comedi.
I hunted around but could not find them, can anyone point me in the
right direction.
Right now I am gutting one of the rtai examples I have and merging it
with the comedi dio.c
example. My goal us just to talk to the digital io on the daq board in
real time.
When I compile the code I get tons of "previously defined" warning and
then the make bails.
What can I do to work around this?
My makefile runs the following
kgcc -Wall -O2 -I/usr/src/linux/include -I/usr/src/rtai/include
-I/usr/src/rtai/newfifos \
-DRTAI_RTF_NAMED \
-o us_appl us_appl.c
kgcc -Wall -O2 -I/usr/src/linux/include -I/usr/src/rtai/include
-I/usr/src/rtai/newfifos \
-DMODULE -D__KERNEL__ -DRTAI_RTF_NAMED \
-o servotmp.o -c simpleDIO.c
My includes are -
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/version.h>
#include <asm/io.h>
#include <rtai.h>
#include <rtai_sched.h>
#include <rtai_fifos.h>
#define PORT 0x378
RT_TASK task_data;
int position=0;
MODULE_PARM(position,"i");
int fifo=0;
#define TIME1ms 1000000
#define TIME19ms 19000000
#include <stdio.h>
#include <comedilib.h>
#include <fcntl.h>
#include <unistd.h>
#include <errno.h>
#include <getopt.h>
#include <ctype.h>
And these are my warnings
kgcc -Wall -O2 -I/usr/src/linux/include -I/usr/src/rtai/include
-I/usr/src/rtai/newfifos -I/usr/src/linux -lcomedi \
