pbApplying Cb is the book you need if you are programming for Single Board Computers SBCs that run Linux, or if you do any coding in C that interacts with the hardware. As there isn't a good name for this body of knowledge, it isn't easy to find a single source for it. This book gathers together all of these low-level, hardware-oriented and often hardware-specific ideas. As such it is a moderately advanced book. This is not to say that it is difficult, but it does presuppose that you already know how to program in C and that you know the basic idioms of C.ppStarting off from the very simple task of making a program run automatically, we look at how your program works with user-mode Linux. If you are working with hardware, arithmetic cannot be ignored and separate chapters are devoted to integer, fixed-point and floating-point arithmetic. Equally, to handle IO you need to have a good grasp of files and the pseudo file system. The devmem file coupled with memory-mapped files makes it pos
