This is another choice serial fiber converter
getting your Arduino
(along with other PIC)
attached to your system (ethernet) - make use of an unwanted NSLU2!
The NSLU2 and Arduino both talk TTL, but the NSLU2 is 3.3v and Arduino is 5v. Very easy fix - add a resistor!
Only 3 cords are required - pins 2, 3
and 4 located on the NSLU2. You may not want to link up
the strength pin.
A the bench less than, try to get the bright white stripe - which is the effectiveness pin.
NSLU2 - pin-outside the J2 serial
dock
Pin 1 - 3.3v, pin 1 includes bright white stripe
adjacent to it
Pin 2 - RXD, are given from Arduino
to NSLU2 (must-have resistor)
Pin 3 - TXD, transmit from NSLU2 to Arduino
Pin 4 - GND, surface relationship
This information is designed in personal reference with regard to the "Freeduino" - a Better
business bureau (bare bones table) variety. Ensure that things are all fueled away from and unplugged. Then, attach the TTL pins tagged "RX", "TX" and "GND" onto the Better business bureau into the adequate pins
with the NSLU2. The Four serial harbour TTL pins along the NSLU2 are seen just below the battery to
the right.
You should space a 10k resistor concerning the
Arduino and the NSLU2 on pin 2 associated with
the NSLU2 so that the
5v from the Arduino are lowered to okay values.
Now force within the NSLU2 and Arduino this really is flased with Debian (SlugOS need to get the job done also). Add minicom (apt-get) and start up minicom and set 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. 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 take a
crack at powering out of equally instruments, energy backup and try again. If you have made
other hardware mods such as overclocking on the NSLU2, it is possible the serial port will not work.
You are required to venue a 10k resistor between
Arduino and so the NSLU2 on pin 2 of a NSLU2 consequently the
5v from the Arduino are lessened to secured concentrations.
Now potential within the NSLU2 and Arduino thats
generally flased with Debian (SlugOS needs to tasks also). Use minicom (apt-get) and begin 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. 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 powering out the two of them products, performance back
up and try for a second time. It is possible the
serial port will not work if you have made other hardware mods such as overclocking on the NSLU2.
