1、介绍</h1>
|
|||
|
|
<p >Agile Button 是基于 RT-Thread 实现的 button 软件包，提供 button 操作的 API。</p>
|
|||
|
|
<ul>
|
|||
|
|
<li>按键操作的状态变化为：<code>未按下 ——> 按下 ——> 未按下</code>。</li>
|
|||
|
|
<li>为了消除干扰，默认的消抖时间为 15ms，可以通过 <code>agile_btn_set_elimination_time</code> API 更改消抖时间。</li>
|
|||
|
|
<li>间隔在 500ms 内的连续操作，记为多次操作，更改对象的 <code>repeat_cnt</code> 属性，通过该属性可获取连续操作次数。</li>
|
|||
|
|
<li>在按下期间会计算对象的持续按下时间，可通过对象的 <code>hold_time</code> 属性获取。</li>
|
|||
|
|
</ul>

2、如何打开 Agile Button</h1>
|
|||
|
|
<p >使用 Agile Button package 需要在 RT-Thread 的包管理器中选择它，具体路径如下：</p>
|
|||
|
|
<div class="fragment"><div class="line">RT-Thread online packages</div>
|
|||
|
|
<div class="line"> peripheral libraries and drivers ---></div>
|
|||
|
|
<div class="line"> [*] agile_button: A agile button package</div>
|
|||
|
|
</div><!-- fragment --><p >然后让 RT-Thread 的包管理器自动更新，或者使用 <code>pkgs --update</code> 命令更新包到 BSP 中。</p>

<li>使用 <code>Doxywizard</code> 打开 <a href="./doc/doxygen/Doxyfile">Doxyfile</a> 运行，生成的文件在 <a href="./doc/doxygen/output">doxygen/output</a> 下。</li>
|
|||
|
|
<li>需要更改 <code>Graphviz</code> 路径。</li>
|
|||
|
|
<li><code>HTML</code> 生成未使用 <code>chm</code> 格式的，如果使能需要更改 <code>hhc.exe</code> 路径。</li>
