Here is another option

(or another PIC)

linked to your network system (ethernet) - make use of past NSLU2!

The NSLU2 is 3.3v and Arduino is 5v, even

though the NSLU2 and Arduino both talk TTL. Straight forward improve - convey a resistor!

Only 3 cables will be required - pins 2, 4 and 3 on your NSLU2. You may not are planning to relate

the energy pin.

For each the family table listed below, try to get the bright white stripe - this is the power pin.

NSLU2 - pin-out from the J2 serial

dock

Pin 1 - 3.3v, pin 1 comes with a whitened stripe next to it

Pin 2 - RXD, collect from Arduino

to NSLU2 (essential resistor)

Pin 3 - TXD, transfer from NSLU2 to Arduino

Pin 4 - GND, soil

interconnection

This information is designed in referrals in the "Freeduino" - a BBB (uncovered bone tissues table) category. Be certain all things are run off and unplugged. Then, be connected the TTL pins labeled "RX", "TX" and "GND" located on the BBB in to the best pins upon the NSLU2. The Four serial slot TTL pins around NSLU2 are

observable just below battery on the right.

It is

important to website a 10k resistor amongst the

Arduino also, the NSLU2 on pin 2 in the NSLU2 to be sure the

5v from the Arduino are decreased to trustworthy heights.

Now impact inside the Arduino and NSLU2 this really is flased with Debian (SlugOS should preferably employment also). Put up minicom (appropriate-get) and commence up minicom and set up the serial dock 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. 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 look into running from each of

these devices, drive validate and try in the future. If you have made

other hardware mods such as overclocking on the NSLU2, it is possible the serial port will not work.

You have to place a 10k resistor between

Arduino plus NSLU2 on pin 2 of an NSLU2 so

the

5v coming from the Arduino are dropped to good heights.

Now effectiveness the NSLU2 and Arduino that is flased with Debian (SlugOS really should services also). Set

up minicom (appropriate-get) and

initiate up minicom and set up the serial dock tottyS0 and 9600, 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. 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 make an effort running off each machines, drive validate and check out in the future. It is possible the

serial port will not work if you have made other hardware mods such as overclocking on the NSLU2.
