[LUNI] breaking into embedded?

[Mike Crawford]

Well, as far as starting in embedded, I would recommend not touching an
operating system.  Start /small/, example an Intel 8051 microcontroller
with 4k ROM and 128 bytes (yes bytes) RAM.  You could start by learning
how they work, but I would recommend finding an application first. 
Think of something to do with it.  For example, LEDs are very easy to
interface with this microcontroller.  Don't go overboard, though, keep
it simple.  From there, start working on the code, in ASM, for the
processor.  Then you assemble the circuit and test it.  Working small
and in ASM really gives you a good understanding and appreciation of the
CPU and it's capabilities.
