"Programming Embedded Systems in C and C++" - читать интересную книгу автора (Barr Michael)

Why I Wrote This Book

I once heard an estimate that in the United States there are eight microprocessor-based devices for every person. At the time, I wondered how this could be. Are there really that many computers surrounding us? Later, when I had more time to think about it, I started to make a list of the things I used that probably contained a microprocessor. Within five minutes, my list contained ten items: television, stereo, coffee maker, alarm clock, VCR, microwave, dishwasher, remote control, bread machine, and digital watch. And those were just my personal possessions — I quickly came up with ten more devices I used at work.

The revelation that every one of those products contains not only a processor, but also software, was not far behind. At last, I knew what I wanted to do with my life. I wanted to put my programming skills to work developing embedded computer systems. But how would I acquire the necessary knowledge? At this point, I was in my last year of college. There hadn't been any classes on embedded systems programming so far, and I wasn't able to find any listed in the course catalog.

Fortunately, when I graduated I found a company that let me write embedded software while I was still learning. But I was pretty much on my own. The few people who knew about embedded software were usually too busy to explain things to me, so I searched high and low for a book that would teach me. In the end, I found I had to learn everything myself. I never found that book, and I always wondered why no one had written it.

Now I've decided to write that book myself. And in the process, I've discovered why no one had done it before. One of the hardest things about this subject is knowing when to stop writing. Each embedded system is unique, and I have learned that there is an exception to every rule. Nevertheless, I have tried to boil the subject down to its essence and present only those things that programmers definitely need to know about embedded systems.
