Hello everyone,
I have been looking online and have bumped into the Lego NXT. Apparently
Microsoft Robotics can be used with this product. I would like to know could
one use the Micro Framework with the NXT. The NXT uses a 32-bit ARM7
microprocessor.

Hello,

We had discussed this on here before. NXT has ARM7 with 256K flash and 32K
RAM. This is enough to run the "core" of .NET Micro Framework but then there
is no room left for your own application. And we will probably have to
remove the debugging capabilities to fit it all in. Now, if we had double
the flash and ram like our USBizi chipset then it can run fine.

An option is to connect NXT to USBizi through I2C connection and then your
main application will be written in C# on VS2008 that will control the NXT.
On the NXT, you will have a small piece of software that will take the I2C
commands coming from USBizi and process them. I say I2C because this is the
only bus exposed on the connectors
http://www.usbizi.com/

Now, when you talk about Microsoft robotics used with NXT, that is because
Microsoft robotics is running on the PC not on the device itself and then it
is controlling the NXT from the PC

Thanks for the reply GHI,
When I found the NXT online it appealed to me because I was quite sure the
microframework would work. Before I spend any $ more research is needed.
Very impressed by the size of the USBizi !!!

Connect the USBizi and the Lego NXT is what I'm trying to do.

Don't you have any exanple of it, or at least any example of I2C connection on USBizi??

You can download the new 4.1 Beta. It contains a working port for the same
processor of the NXT. I2C included.
