15 <p>The General-Purpose Input/Output (GPIO) gives access to the MCU pins.
16 The GPIO can be interfaced through a peripheral bus or the local bus.</p>
20 <h2>GPIO Software Driver</h2>
22 <p>This driver provides an API to get access to the main features of the GPIO controller.</p>
24 <p>The driver is composed of <a href="gpio.c">gpio.c</a> and <a href="gpio.h">gpio.h</a> (for accurate API description, read this header file).</p>
27 <h2>GPIO Software Driver Examples</h2>
28 <p>Two examples are currently available:
29 <li><a href="./PERIPHERAL_BUS_EXAMPLE/readme.html"> demonstrates the peripheral bus interface</a>;</li>
30 <li><a href="./LOCAL_BUS_EXAMPLE/readme.html"> demonstrates the local bus interface</a>.</li>
