Hi at all, it is possible to use in a single board mx32 board with the wifi shield and the ethernet shield?

I don't see any reason that it could not be done, but I haven't played with any WiFi shields so I don't know if there would be any gotchas.

The problem is if your a new at this and there are gotchas, they will be difficult to solve.

In theory it's very possible. The first thing to do is map the pins between the different devices (or shields if using shields) to see if any of them will have a conflict. Note that just because both the network and the WiFi shield share a pin, does not in itself mean a conflict, just that you need to investigate.

Then you need to work out what you want to do with the WiFi side. Many WiFi modules used on shields have limitations on how many sockets (connections) they can handle. So if your thinking of creating a WiFi <-> Ethernet bridge or router for example, then you need to be looking for a more advanced module something like the RS9110-N-11-22-04 WiFi module from Redpine which allows for real "Socket" connection over WiFi for example with EMX module you can open up to 127 TCP/UDP sockets simultaneously with SSL security.

hi, excuse me for late in response on your reply. Thanks Jacob and smitthhyy for your response. So i'm a newbie and i investigate on it following your advice. My first problem is to understand if the libraries provided by chipkti for using this modules (DNETck and DWIFIck) permits the use of the module together. That i want to make is to send the same flow of information through the wifi and ethernet module.

Knowing the people that wrote the dk libs and there programing philosophies my guess is you will have no problems at all. I've briefly played with the libs at Masters last year in a class put on by Digilent.
