The NuttX Real Time Operating System

NuttX is a tiny embedded operating system (OS).  The summary version of what NuttX is good for is:

• RTOS
• Has most of the features of Linux
• Small ROM footprint – fits on microcontrollers with  32KB  flash e 8KB RAM.  This is pretty small.

I spoke today with Alan Carvalho de Assis who specializes in the NuttX RTOS.    This is an article that discusses the advantages of NuttX written by Alan.

What is the NuttX RTOS and why should you care?
