"after the above you will almost be able to do your first project such as 'blinky' "

Though it sounds intimidating ( that one should go through all the learning before he can come with a "Blinky" code ) I feel that is the ground reality. Proficiency in embedded stuff is a lot different from a fluency in either software or hardware alone. It is both and there lies the problem at first glance. Look deeper and you will realize that the "problem" has a layer just beneath it called opportunity. Once the attitude to handle both hardware and software sets in then you become an addict of embedded systems.
