avrtoolbox and C Standard Library

摘要

This Workshop marks a milestone in the development of the avrtoolbox. It is the end of the beginning. We have discussed some useful software engineering concepts and applied them to processes for an Open Source project (http://code.google.eom/p/avrtoolbox). We have applied these processes to the development of the libraries in libavr. Now, we will finish this beginning by learning about the venerable C standard library. We will look in detail at one of the venerable functions from that library: printfQ (as it has been tweaked by avrlibc to work on the AVR); and we will look at some other standard functions that we'll apply to writing a simple command line interpreter. Our demonstration program will prove very useful for our future software development and testing.
