Let's be systematic.
1. You are using owserver and owfs? owhttpd?
2. You are reading the DS2405/sensed and temperature at the same time. Is
this required?
3. USB?
4. Versions?
i'm using this script to start onewire:
/etc/rc.d/ow restart
#!/bin/bash
. /etc/rc.conf
. /etc/rc.d/functions
case "$1" in
start)
/usr/bin/owserver -p 1234 -d /dev/ttyS0
/usr/bin/owhttpd -p 90 -s 127.0.0.1:1234
;;
stop)
killall owserver
killall owhttpd
;;
restart)
$0 stop
sleep 1
$0 start
;;
*)
echo "usage: $0 {start|stop|restart}"
esac
exit 0
i have an owhttpd interface to list onewire with browser
and i'm using PHP library to get and put values
the php program is something like this:
$pid=pcntl_fork();
if ($pid == -1){
die("Could not fork\n");
}elseif($pid==0){
// here i just read onewire and put on database
the last read value like:
init("127.0.0.1:1234");
while (1){
read database for some output
put("/uncached/%ds2405
device%/PIO",$output_value);
usleep(10000); // don't have high CPU
usage
}
}else{
// here i just read onewire and put on database
the last read value like:
init("127.0.0.1:1234");
while (1){
get("/uncached/%DS18S20
device%/temperature")
get("/uncached/%DS18B20
device%/temperature")
get("/uncached/%DS2405 device%/PIO")
get("/uncached/%DS2405 device%/sensed")
update last state on mysql database
usleep(10000); // don't have high CPU
usage
}
}
