This is an alternative My explanation to get your Arduino
(or any other PIC)
linked to your system (ethernet) - make use of former NSLU2!

The NSLU2 and Arduino both talk TTL, but the NSLU2 is 3.3v and Arduino is 5v. Simple mend - put in a resistor!

Only 3 cables will be required - pins 2, 3
and 4 towards the NSLU2. You may not hope to join
the strength pin.
A the kitchen table here, seek for the white stripe - which is the strength pin.

NSLU2 - pin-from the J2 serial harbour

Pin 1 - 3.3v, pin 1 comes with a vivid white stripe alongside it

Pin 2 - RXD, collect from Arduino
to NSLU2 (essential resistor)

Pin 3 - TXD, transfer from NSLU2 to Arduino

Pin 4 - GND, soil connection

This information is written in research to the "Freeduino" - a Better
business bureau (uncovered bone fragments table) variation. Be
sure things are fueled off and unplugged. Then, connect the TTL pins marked "RX", "TX" and "GND" at the Better business bureau to
the proper pins
with the NSLU2. The 4 serial harbour TTL pins on the NSLU2 are recognizable just beneath battery to the correct.

You should web site a 10k resistor within the
Arduino and NSLU2 on pin 2 to the NSLU2 consequently the
5v from the Arduino are lessened to protected concentrations.

Now force along
the Arduino and NSLU2 thats
generally flased with Debian (SlugOS have to succeed also). Use minicom (apt-get) and get started up minicom and set up the serial dock tottyS0 and 9600, 8N1.

If the connections are correct, the TTL pins/port on the Arduino and NSLU2 are functional you should now see the output
from the Arduino. Be sure you have pre-programmed your Arduino with a program that outputs text
at the proper baud rate if you do not see anything. Also check out powering off of both together devices, ability backup and check out more. If you have made
other hardware mods such as overclocking on the NSLU2, it is possible the serial port will not work.

You will need to arrange a 10k resistor in between the
Arduino therefore the NSLU2 on pin 2 in the NSLU2 therefore the
5v coming from the Arduino are reduced to secured
grades.

Now potential in the NSLU2 and Arduino this really is flased with Debian (SlugOS should
probably task also). Put in minicom (apt-get) and
initiate up minicom and set the serial harbour to9600 and
ttyS0, 8N1.

The TTL pins/port on the Arduino and NSLU2 are functional you should now see the output from the Arduino
if the connections are correct. If you do not see anything, be sure you have pre-programmed your Arduino with a program
that outputs text at the proper baud rate. Also test running away from both units, provide power to back
up and attempt more. If you have made
other hardware mods such as overclocking on the NSLU2, it is possible the serial port will not work.
