hi,
Is the ethernet shield v2.0 compatible with the arduino fio? and can I use arduino uno and fio simultaneously with the ethernet shield?
I'm working on a monitoring system project, I need to assign to each arduino an IP address, I will program the uno to read from the sd card through the browser, and want to program the fio to send wirelessly a readings from some sensors to the ethernet shield and view the results on the browser with different IP address than the one assigned for the uno.
but the problem that until now I couldn't even let the fio work alone with the shield.
this is a sample code I want to program the arduino fio with, but i couldn't get the readings on the browser, even that when i use the same code on the uno it will work without any problems...
any help guys? Thanks
