(or another PIC)
plugged into your system (ethernet) - work with an vintage NSLU2!
The NSLU2 and Arduino both talk TTL, but the NSLU2 is 3.3v and Arduino is 5v. Fairly simple take care of - incorperate a resistor!
Only 3 cords are required - pins 2, 4 and 3 by the NSLU2. You may not
prefer to join up
the ability pin.
Per the desk listed below, look out for the light stripe - which is the electrical
NSLU2 - pin-right out of the J2 serial
Pin 1 - 3.3v, pin 1 provides a vivid white stripe beside it
Pin 2 - RXD, are given from Arduino
to NSLU2 (requires resistor)
Pin 3 - TXD, transmit from NSLU2 to Arduino
Pin 4 - GND, flooring relationship
This article is developed in referrals onto the "Freeduino" - a BBB (bare bone tissues table) sort. Check that everything
is driven out of and unplugged. Then, hook up the TTL pins tagged "RX", "TX" and "GND" inside the BBB into the
recommended pins onto
the NSLU2. The 4 serial slot TTL pins on the NSLU2 are evident just beneath the battery to
It is best to position a 10k resistor between
Arduino as well as the NSLU2 on pin 2 of a NSLU2 so that the
5v from the Arduino are minimized to free from harm values.
Now vitality inside the Arduino and NSLU2 this is flased with Debian (SlugOS would be wise to
efforts also). Put in minicom (apt-get) and commence up minicom and set the serial port 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. 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 look into powering away from at the same time models, vigor back and check out again. It is possible the
serial port will not work if you have made other hardware mods such as overclocking on the NSLU2.
It is best to location a 10k resistor in between the
Arduino so the NSLU2 on pin 2 of that NSLU2 hence the
5v from the Arduino are decreased to protected degrees.
Now vigor in the NSLU2 and Arduino that is flased with Debian (SlugOS can career also). Add minicom (appropriate-get) and get started up minicom and set the serial harbour 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 try out running off the two of them devices, potential back
up 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.
