| <h2>HAL API<a class="headerlink" href="#hal-api" title="Permalink to this headline">¶</a></h2> |
| <p>A HAL always includes header file with function declarations for the HAL |
| functionality in <code class="docutils literal notranslate"><span class="pre">/hw/hal/include/hal</span></code>. The first argument of all |
| functions in the interface typically include the virtual device_id of |
| the device you are controlling.</p> |
| <p>For example, in |
| <code class="docutils literal notranslate"><span class="pre">`hal_gpio.h</span></code> <<a class="reference external" href="https://github.com/apache/incubator-mynewt-core/blob/master/hw/hal/include/hal/hal_gpio.h">https://github.com/apache/incubator-mynewt-core/blob/master/hw/hal/include/hal/hal_gpio.h</a>>`__ |
| the device enumeration is the first argument to most methods and called |
| <code class="docutils literal notranslate"><span class="pre">pin</span></code>.</p> |
| <div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="go">void hal_gpio_write(int pin, int val);</span> |
| </pre></div> |
| </div> |
| <p>The device_id (in this case called <code class="docutils literal notranslate"><span class="pre">pin</span></code>) is not a physical device |
| (actual hardware pin), but a virtual pin which is defined by the |
| implementation of the HAL (and documented in the implementation of the |
| HAL).</p> |
