Abstract
General-purpose I/O is a topic near to the hearts of Raspberry Pi owners, because this is the interface to the outside world. The BCM2835 is flexibly designed to allow I/O pins to be reconfigured under software control. GPIO 14 can be an input, an output, or operate as a serial port TX data line, for example. This makes the Raspberry Pi very adaptable.
