Raspberry Pi Hardware Reference
This book is focused mainly on the Raspberry Pi’s hardware. The content is extracted from the complete work, Mastering the Raspberry Pi. As such, it will serve you as an owner’s manual of sorts, saving time as a ready reference about the hardware you purchased. While this is a volume focused on hardware, some software coverage must coexist. For example, it is through the physical memory management that software gains access to the hardware peripheral registers. Another example is the discussion about the CPU, where the pthread API is covered for reference purposes. Through the application of this API, you further utilize that ARM CPU. This book begins by introducing the Pi in general terms in Chapter 1. Then attention immediately turns to the important topic of power in Chapter 2. Many people suffer needless problems because of neglect in this area. The chapter ends with some notes about running from battery or solar power. Chapter 3 documents the header strips, LEDs, and Reset inputs. This is information that should be bookmarked. Next is Chapter 4 on memory, which documents the various Raspbian Linux measures and controls for memory allocation. The CPU and its API are described in Chapter 5. The focus of Chapter 6 is USB. USB-specific power issues and its API are explained. Wired and wireless Ethernet networking is discussed in Chapter 7. SD card technology is examined in Chapter 8, describing the interface and the specifics of the Raspberry Pi interface. The topic of wear leveling is also included. Serial communication, RS-232 converters, serial consoles, and dedicated serial ports are covered in Chapter 9. The serial interface, some historical influences, and flow control are discussed. Included is an organized description of the Linux API for utilizing the serial interface.
