Here a working example with a 16-Bit ring with radio because the misses hit the fence for the second time this year with the car.



Sensor in action <--Video

Ok here's the deal to change the channel or other settings:

cd Raspberry
make clean
make all
sudo make install
Done!

Starting up the library
To initialize radio and start the library, you must call begin(). Begin initializes the sensor node but you can also configure the sensor node operating parameters manually. Call this before anything else in the library

void begin(void (*_msgCallback)(const MyMessage &), uint8_t nodeId, boolean repeaterMode,
uint8_t parentNodeId);
incomingMessageCallback - Callback function for incoming messages from other nodes or controller and request responses. Default is NULL.
nodeId - The unique id (1-254) for this sensor. Default is AUTO(255) which means sensor tries to fetch an id from controller.
repeaterMode - Activate repeater mode. This node will forward messages to other nodes in the radio network. Make sure to call process() regularly. Default in false
parentNodeId - Use this to force node to always communicate with a certain parent node. Default is AUTO which means node automatically tries to find a parent.

Nice!
So gw.begin(NULL,4,true,3) is node 4 with repeater mode on and parent 3? Cool!

Keep me posted!
Will order when board comes soldered and ready to use!

@gohan Yes I know but the pinout 53, output not. That was all that was needed eventually .

So here is the deal!
You need to set Pin 53 to Output in your sketch and wire from 50-53 instead of 10-13.
It's working now

This line is not necessary in MYS 2.0

Maybe post the code so that people can see what is wrong with your code

Example sketch is also not working...
Ditto for the ICSP connection header
It must be the wires!

I also believe it has to be something with the wireing. I will check this tonight when I'm going to try it on the ICSP header.
And to test it with the default sketch!

Fellow board members,

I've got a Arduino Mega 2560 in my shed which I would like to function as a GW by Ethernet.
I've got the code right for MYS 2.0 so that is not the problem I think.

I've got an W5100 Ethernet module connected to the ports 50-53 and 5+ and GND on my Arduino Mega. Fixed IP and valid MAC address. When I debug my Mega it says IP: 0.0.0.0 but when I connect the same module with the same code to a Nano on the ports as advised than debug It says IP: 192.168.1.80 as programmed.

On what pins do I need to connect my W5100 on my Mega?
Is it on the middle PIN's? or just the 50-53 pins?
Do I need some changes in the code? For example SoftSPI enable?

Again: Nano connected with same code and same module: OK!
Mega connected with same code and same module: IP 0.0.0.0

Can somebody point me in the right direction?

The first one will not compile since the #include <SPI.h> is missing

I've got the same error but the thing missing is incluse spi.h somewhere below...
