RBBB & EtherCard

Direct connect between RBBB and EtherCard:

RBBB >>> EtherCard
D13  >>> SCK
D12  >>> MISO
D11  >>> MOSI
D8   >>> B0
RST  >>> RST
PWR  >>> PWR
GND  >>> GND

If you get “error: WProgram.h: No such file or directory” while compiling, make sure to change

#include "WProgram.h"


#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#include "WProgram.h"
in the header files of included libraries.

If you are using “custom hardware” like having a naked 328p on a breadboard and you get an error like “pins_arduino.h: No such file or directory” when trying to compile, just add the following line to the relevant boards.txt:

The complete block in your boards.txt could look like this:

Using the most recent Arduino IDE 1.0.2 one has to setup the following to get the Jeenode v5 working:

As board select: “Arduino Duemilanove w/ ATmega328”

For the Serial Monitor choose: 57600 baud

To get the FTDI Basic USB to Serial Adapter working on Win7 have a look here:


Wohoo! stalker and uno talking to each otherI got the communication up and running.

receiving timestamp, temperature and humidity

Have two of them ready now.
