Note, I'm only halfway through, but I am reading it pretty closely. This book really uses redundancy (let's call it a teaching mechanism), but this gets irritating very quickly. By about the 7th chapter, we have been told it seems like a dozen times that the Propeller's eight cogs are absolutly identical. Halfway through the book, we are still looking at the same simple LED blink example listed over and over, with the same explanation about PUB and PRI methods. The term Object is defined several times, and so on.



Also, there is some poor proofreading. In a (repeated) schematic, an LED "points" the wrong way (or is connected to the wrong power rail). One reused example code wherein a couple of code line changes are made still has the comments against them for the previous example. A chapter supposedly dealing with thouroughly understand a single gog concludes mysteriously with a multi-cog example. A photo is referenced as a schematic, and vice versa.



But, if you can get past the irritations, it's not too bad. I have gained some insight, and expect the hardware interfacing chapters to be better.
