【Follow me第二季第3期】任务4：设计一个类似信号发生器功能的例程
本帖最后由 左手阿飞 于 2025-1-14 12:21 编辑<p>最后扩展任务，设计一个类似信号发生器例程。</p>
<p>信号发生器需要有相应波形的原始波形数据。</p>
<p>在这个任务卡了很多天了，也参考了其他大佬的帖子，但是还是没搞定，做了一些二级菜单，波形出不来。</p>
<p>展示一下现有成果吧。</p>
<p>增加了一个一级菜单，</p>
<pre>
<code class="language-cpp">static st_menu_fn_tbl_t s_menu_items[] =
{
{"Wave Generator" , wave_generator},
{"Hello Information" , Hello_display_menu},
{"Kit Information" , kis_display_menu},
{"Web Server" , eth_emb_display_menu},
{"Network Name Lookup" , eth_www_display_menu},
{"Quad-SPI and Octo-SPI Speed Comparison", ext_display_menu},
{"Cryptography and USB High speed (MSC)" , enc_display_menu},
{"Next Steps", ns_display_menu },
{"", NULL }
};</code></pre>
<p> </p>
<p> </p>
<p>在菜单中加入选项。但是在增加波形，编译就通不过了。</p>
