How to setup the automatic kernel driver loading for the DS2482-x family

[GoogleCodeExporter]

- It is assumed that the WebIOPi user is "pi"

- Copy the attached shell script (ds2482.sh) into your home directory (/home/pi)

- Make it executable (chmod 755)

- You can call it manually (sudo ./ds2482.sh) if you don't need automated start 
at boot

- To get it started automatically at boot, insert the following lines at the 
end of /etc/rc.local just before the last line which is "exit 0" (e.g. with 
"sudo nano /etc/rc.local"):

# Load 1-wire DS2482 master kernel drivers
sudo bash /home/pi/ds2482.sh

- Reboot

As example, I have also attached a rc.local file, yours may contain additional 
instructions.

To finish or disable the automatic loading, delete the lines or comment them 
out.

Additional info:

If you only use a 2482 and/or use GPIO 4 without a pullup resistor, delete line 
3 from the script (it loads w1-gpio with the pullup parameter), you don't need 
it.

I did not test so far what happens when having multiple 2482 chips on the I2C 
bus using different I2C slave addresses for them and having multiple 
tee-commands in the script. So for the time being, use the 2482-800 for 1-wire 
multi channel architectures, it was tested and worked and gives you 8 separate 
1-wire channels.
