This is another option extended-temperature">Killer deal to get your Arduino
(or any other PIC)
connected to your networking (ethernet) - make use of former NSLU2!
The NSLU2 is 3.3v and Arduino is 5v, even
though the NSLU2 and Arduino both talk TTL. Fairly simple
repair - incorperate a resistor!
Only 3 cords will be required - pins 2, 3
and 4 about the NSLU2. You may not just want to link
the power pin.
A the dinner table on the next paragraphs, try to look for the white colored stripe - which is the electric power pin.
NSLU2 - pin-right out of the J2 serial
Pin 1 - 3.3v, pin 1 posesses a vivid white stripe near to it
Pin 2 - RXD, receive from Arduino
to NSLU2 (recommended resistor)
Pin 3 - TXD, send out from NSLU2 to Arduino
Pin 4 - GND, ground connection
This post is printed in
reference point into your "Freeduino" - a BBB (uncovered bone fragments table) sort. Ensure things are operated away from and unplugged. Then, connect the TTL pins branded "RX", "TX" and "GND" on your Better business bureau on the way to ideal pins on a NSLU2. The Four serial harbour TTL pins relating to the NSLU2 are obvious just below the battery to
You ought to region a 10k resistor amongst the
Arduino plus the NSLU2 on pin 2
from the NSLU2 so
5v coming from the Arduino are decreased to free from harm amounts.
Now performance within the NSLU2 and Arduino this is flased with Debian (SlugOS ought to deliver the results also). Set
up minicom (apt-get) and get started up minicom and set up the serial harbour 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 look into running away both the items, vitality back and try ever again. If you have made
other hardware mods such as overclocking on the NSLU2, it is possible the serial port will not work.
You must space a 10k resistor in between the
Arduino and also the NSLU2 on pin 2 of a NSLU2 hence the
5v from the Arduino are cut down to safe and sound ranges.
Now drive in the NSLU2 and Arduino this is flased with Debian (SlugOS really need to task also). Put in minicom (apt-get) and start up minicom and set up the serial port 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 attempt running out of both of the systems, potential backup and attempt back again. It is possible the
serial port will not work if you have made other hardware mods such as overclocking on the NSLU2.
