Note: The Artful Sourcing site has been discontinued. We will try to post Jimmy’s article here at a later date.
My friend Jimmy Sheffield has written an excellent article on embedded systems on the Artful Sourcing blog.
You can find the article at this link.
Jimmy is founder of Level 3 Systems and is an authority on embedded systems and electronics development in general. Without reservation I recommend Jimmy and Level 3 Systems for contract design and development work.
