 232 <p>Driver API for GPIO Interface (Driver_GPIO.h) </p>
 233 <p>The <b>General-purpose Input/Output Interface</b> (GPIO) features Input/Output operations on pin level (does not support simultaneous operations on multiple pins belonging to the same port).</p>
 234 <p>Features:</p><ul>
 235 <li>basic pin configuration (direction, output mode, pull-resistor, event trigger) excluding advanced settings (drive strength or speed, input filter, ...),</li>
 236 <li>events on edge detection,</li>
 237 <li>setting outputs,</li>
 238 <li>reading inputs.</li>
 239 </ul>
 240 <p>Each function operates on a pin level and uses a pin identification as the first parameter. Pin identification is a virtual number which is mapped to an actual pin.</p>
 241 <p><b>GPIO API</b></p>
 242 <p>The following header files define the Application Programming Interface (API) for the GPIO interface:</p><ul>
 243 <li><b>Driver_GPIO.h</b> : Driver API for GPIO Interface</li>
 244 </ul>
 245 <p>The driver implementation is a typical part of the Device Family Pack (DFP) that supports the peripherals of the microcontroller family.</p>
 246 <p><b>Driver Functions</b></p>
 247 <p>The driver functions are published in the access struct as explained in <a class="el" href="theoryOperation.html#DriverFunctions">Common Driver Functions</a></p><ul>
 248 <li><a class="el" href="group__gpio__interface__gr.html#structARM__DRIVER__GPIO">ARM_DRIVER_GPIO</a> : access struct for GPIO driver functions</li>
 249 </ul>
 250 <p><b>Example Code</b></p>
 251 <p>The following example code shows the usage of the GPIO interface.</p>
