Do anyone have any information on how to interface XBee XB24 to FEZ Cerb40, appreciate any help.

Welcome to the forum Nila.

When you say interface, I will assume you mean how to wire the XBee. You can find the Cerb40 pinout here: http://wiki.tinyclr.com/index.php?title=FEZ_Cerb40_Developer . An Xbee communicates over UART, so you have a couple choices:

PA2, UART2 TX
PA3, UART2 RX
or
PB10, UART3 TX
PB11, UART3 RX

GND and 3.3V pins are on the bottom right of the board pictured at the link above.

Thanks, but now I am having other problem. The FEZ Cerb40 when connected to usb is not detected.
Is there A usb driver that I need to install?

@ Nila - are you feeding it 3.3v ? As per the wiki page:

[edit] 3.3V Regulator

Users have the option of providing 3.3V to FEZ Cerb40 or soldering a 3.3V regulator and 47uF capacitors like T520B476M008ATE035 Digikey Mouser. The regulator is a very common LM1117MPX-3.3 regulator in SOT-223 package, found at many online stores including Mouser and DigiKey.

Providing 3.3V through one of the 2 options is required. FEZ Cerb40 will not run if you simply plug in the USB cable.

You’re right, I actually plug directly to the USB. I will get the parts to fix it.

Thanks

@ Nila - your welcome, have fun :slight_smile:

FYI - we’ve been trying to convince GHI to offer a parts kit for these optional components. I can also offer them as an option with the cerb40 proto board, http://wiki.tinyclr.com/index.php?title=Cerb40_Prototyping_Platform .

@ Gus - nudge, nudge…

@ ransomhall - you forgot the wink, wink… :slight_smile:

@ Justin you forgot the “say no more!”

Thanks to all, I will update once I have my cerb40 working with xbee.
