I'm not sure if this is the right forum to post this question, but if I'm wrong I'm sure a mod will move my post... Ok, so I'm taking a class called "Microprocessors and Computer Organization," and it's killing me! First off, it is incredibly boring (assembly language :yuck: ) , and secondly... the textbook SUCKS!! The chips we are using are the Motorola 68HC11 & 68HC12. The book we are using is "Introduction to Embedded Microprocessor Systems" by Jonathan W. Valvano. This book is terribly organized and hard to read. Is there another book that uses this chip to explain concepts that you guys know about? I am dying for another textbook!! Thanks!
