rtai3.1-> lxrt and comedi

[martin.my at gmx.de]

Hi all,

i have maked my first stepp's on LXRT, thanks to Gilles and Poalo for the
link's for "lxrt compiling-problem"

I have install the comedi driver on my system. 
comedi-0.7.68
comedilib-0.7.21

kompiling was ok (rtai3.1 and comedi)
With a small Linuxprogramm i have test the funktion of mein NI-Card. Thats
all ok, in the kernel mode is it possible too.

But now i would like test the card in lxrt.
The programm start and execute the while command, but nothing doing on the
port. When the while command is finish, jump the port on 5V.

....
....
rt_set_periodic_mode();
tick_period = start_rt_timer(nano2count(4000000) );

rt_task_make_periodic(hrttsk, rt_get_time() + tick_period,tick_period);
	{
	while(j<20)
	{	
	ret=comedi_dio_write(device,subdevice,chanel,0);
	if(ret != 1)printf("Fail von chanel %d by output 0\n",chanel);
	if(i==0)
	{ 
	printf("Output on Chanel %d with LOW Bit\n",chanel);
	i=1;
	}
	rt_task_wait_period();
	ret=comedi_dio_write(device,subdevice,chanel,1);
	if(ret!=1)printf("Fail von chanel %d by output 1\n",chanel);
	if(i==1)
	{ 
	printf("Output on Chanel %d with HIGH Bit\n",chanel);
	i=2;
	}
	printf("%d\n",j);
	j++;
	}//end while
		
	}

	//rt_make_hard_real_time();
	

	printf("Stopping of Timer and delete RT_Task\n");
	stop_rt_timer();
	rt_task_delete(hrttsk);
	while(1) { sleep(3); printf("BACKGROUND PROCESS STILL RUNNING\n"); }
	return 0;
}//end main

The insmod of the modules was i think so ok.
