Header Strips, LEDs, and Reset,In this chapter, an inventory of the Raspberry Pi header strips, LEDs, and reset button connections is covered. These are important interfaces from the Pi to the outside world. You may want to use a bookmark for Table 3-3, which outlines the general purpose input/output (GPIO) pins on header strip P1.

SD Card Storage,The file system is central to the Unix system design, from which Linux borrows. The necessary mass storage requirements have traditionally been fulfilled through hard disk subsystems. However, as Linux hosts become as small as cell phones, flash memory technology has replaced the bulky mechanical drive.

1-Wire Driver,The 1-Wire protocol was developed by Dallas Semiconductor Corp. initially for the iButton.. This communication protocol was attractive enough to be applied to other devices and soon adopted by other manufacturers. This chapter provides an overview of the 1-Wire protocol and how it is supported in the Raspberry Pi.

SPI Bus,The Serial Peripheral Interface bus, known affectionately as ., is a synchronous serial interface that was named by Motorola.. The SPI protocol operates in full-duplex mode, allowing it to send and receive data simultaneously. Generally speaking, SPI has a speed advantage over the I2C protocol but requires more connections.
