Disable Serial Port Login:
To enable the serial port for the RPi-extension you need to disable login on the port. There are two files that need to be edited.
The first and main one is /etc/inittab
This file has the command to enable the login prompt and this needs to be disabled. Edit the file and move to the end of the file. You will see a line similar to:
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
Disable it by adding a # character to the beginning.
#T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
Save the file.

Disable Bootup Info:
Disable it by editing the file /boot/cmdline.txt .
The contents of the file look like this:
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait
Remove all references to ttyAMA0 (which is the name of the serial port). The file will now look like this:
dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait
Save the file.

Alle drei Busmaster aktivieren:
rc.local bearbeiten:
echo ds2482 0x18 > /sys/bus/i2c/devices/i2c-1/new_device
echo ds2482 0x19 > /sys/bus/i2c/devices/i2c-1/new_device
echo ds2482 0x1a > /sys/bus/i2c/devices/i2c-1/new_device
Save the file.

Ob alle drei Busmaster aktiv sind kann man mit:
ls /sys/bus/w1/devices/
überprüfen.

Reboot
In order you enable the changes you have made, you will need to reboot the Raspberry Pi:
sudo shutdown -r now
