I'm aware of a "DT_INTS" type book in the works based on the marvelous contributions made by the late great Daryl Taylor. It doesn't compete with the myriad of code, libraries, and examples available for other platforms, but please don't discount the courageous efforts being taken by a select few in the PBP camp. Having looked into various offerings, I chose PIC and PBP for my reasons. I try to contribute where I can, and I sincerely hope the PBP/PIC niche will continue to grow & evolve. Instead of complaining about the lack of support, I try to give it in hopes that others will respond in kind when I need help. The simple answer is if you find yourself more comfortable with Audrino (or any other platform), work with it.
