1-Wire Temperaturf\u00fchler ist offenbar m\u00f6glich via OSS-Button GPIO.
\nD.h. hinter dem Taster einfach den SMD-Kondensator entfernen, dann D und GND direkt am Taster anl\u00f6ten. (Via Durchgangspr\u00fcfer findet man ganz einfach heraus, was was ist). +3,3 V einfach von vorne von einer LED nehmen.<\/p>\n

Pakete installieren :
\n
\nopkg update
\nopkg install kmod-w1 kmod-w1-gpio-custom kmod-w1-master-gpio kmod-w1-slave-therm - 3.10.49-1
\n<\/code><\/p>\n

Damit das auch funktioniert, m\u00fcssen die Module in der richtigen Reihenfolge und das eine mit den richtigen Parametern gestartet werden. Dazu hab ich einfach das in ein Init-Script gepackt :
\n
\n sleep 30<\/p>\n

rmmod gpio_button_hotplug<\/p>\n

rmmod gpio-buttons
\n rmmod wire
\n rmmod w1_therm
\n rmmod w1_gpio
\n insmod w1-gpio-custom bus0=0,12,0 # GPIO12 = QoS button
\n insmod w1-gpio
\n insmod w1_therm
\n<\/code><\/p>\n

Auslesen l\u00e4sst sich der F\u00fchler dann mit :
\n
\ncat \/sys\/devices\/w1_bus_master1\/28-xxxxxxxxxx\/w1_slave | grep \"t=\" | cut -d\"=\" -f2
\n<\/code>
\n(das xxxxxx ist nat\u00fcrlich durch die echte Seriennummer zu ersetzen)<\/p>\n

Zus\u00e4tzlich hab ich noch 2 LAN LEDs angezapft, damit ich via H-Br\u00fccke ein Bistabiles Relais schalten kann :<\/p>\n
