It sounds like you have a development board with an embedded Forth
system on it. Quite different to the graphical integrated development
environments and optimising compilers that MPE and Forth Inc. sell.

@ and ! are used to read from and write to memory locations.
Generally you build your device drivers up from there. Your system
might already have words defined for interfacing to the hardware in
the eval board or it might not (the manuals should tell you).

Forth has a steep learning curve, but it's a powerful tool once you
know how to use it.

You might want to try chatting to the guys on the #forth channel on
the Freenode IRC network.
