How you can see here:


it's 1001101 for adress and 0 or 1 to read or write.
Code:
Wire.beginTransmission(0b10011010);

i have the same problem :S

the correct way:

1-Connect SEN to a digital pin to control it.
2-Connect RFM12 SS to the SEN of ethernet.
3-Set the Ethernet's SS to 1,  and SEN to 0,  to talk to the RFM12.
4-Set the Ethernet's SS to 0,  and SEN to 1,  to talk to the Ethernet.

Yes, RFM12 use the pin 2 (PD2) for interrupts.
but i looked at the http://arduino.cc/en/uploads/Main/arduino-ethernet-shield-schematic.pdf ethernet shematic and the ethernet don't use that pin :s

Thanks for all yours help.

Edited:

First Try.
1-Connect SEN to a digital pin to control it.
2-Connect RFM12 SS to the SEN of ethernet.
3-Set the Ethernet's SS to 1,  and SEN to 0,  to talk to the RFM12.
4-Set the Ethernet's SS to 0,  and SEN to 1,  to talk to the Ethernet.

It's that?

And if in last option i use an mux to mux the 10 11 12 13 to the two devices?

        / RFM12
10  --
        \ Ethernet

        / RFM12
11  --
        \ Ethernet

        / RFM12
12  --
        \ Ethernet

        / RFM12
13  --
        \ Ethernet

I will receive my ethernet shield friday. I bought it to tinker.it.

So the first thing to do is try to use rfm12 with another /SS pin ? And after try to use it with the ethernet.

kg4wsv do you have an idea?

LAST OPTION: And if connect the shield in a breadboard and after i use a mux?

I'm using that library http://code.google.com/p/jeelabs/source/browse/trunk#trunk/libraries/RF12%3Fstate%3Dclosed

The device is a RFM12

Any idea of how i can use ethernet shield and another SPI device? I'm think in a mux but the ethernet shield will always connect to arduino :S

I don't know if i'll have a lot of time but i can try smiley

I want to use a webserver on the arduino and send to it a text from another page. Can you give a link or an ideia how i use the POST, i know that i have the POST and GET but i don't know how to use it.

Hi,
Can you tell how can i send a text from an input text in a html page to the arduino?

I have a page in a server (not arduino) where i have a input text. I want to send the text from input to a arduino with a ethernet shield.

Thanks

GordonEndersby
the code that you posted in the first post work with ds1337?

ok, thanks.
I tested to measer current and i used one of that http://www.allegromicro.com/en/Products/Part_Numbers/0712/ with no problem but i had to cut the wires :p

What is a CT?
