title: Real Time Operating Systems for Embedded Systems -> Good Starting books
body: <p>I have worked extensively on AVR microcontrollers. I haven't had a proper OS course at UNI..not from a CS branch, but I want a book that gives me generic OS concepts as well as RTOS concepts for embedded systems. Any suggestion?. Something that details a particular OS like TinyOS or FemtoOS would be nice, but I want something with API based examples/codes as well.</p>
  
  <p>Any suggestions  ?</p>
