【FM33LG0系列开发板测评】02.基础工程（LED、KEY、LPUART、LPTIM、SHELL）
<p>在准备好开发资料和搭建好开发环境后，我们就要来准备一个基础工程了；好的基础建设是搭建高楼大厦的关键，所以在基础工程中使用的原创的TASK任务管理调试方式，为了方便后期程序的调试、测试和演示，我们又添加了NR_MICRO_SHELL开源代码，可以使用串口终端方便的对接正在运行的程序；</p><p> </p>
<p>本次的基础工程包含从零开始新建工程、LED、KEY、LPUART、LPTIM、SHELL等多个方面，所以篇幅有些长，但满满的都是干货，有启发和帮助哦……</p>
<p> </p>
<p>从零开始新建立工程：</p>
<p>我们使用KEIL开发环境进行开发，所以提前安装好了芯片支持包；打开KEIL软件，点击菜单栏Project->New uVision Project...在弹出的对话框中选择工程存放的路径及工程名，点击保存，如下图所示：</p>
<p></p>
<p>在Select Device for Target窗口中选择芯片型FM33LG04X，然后在弹出的Manage Run-Time Environment窗口直接点击OK，新建的空工程就完成啦；如下图所示：</p>
<p></p>
<p>接下来我们需要往新建的空工程中划分程序结构以及添加程序源代码，点击工具栏上的Manage Project Items按钮，在弹出的窗口中进行操作，完成后点击OK，就完成啦；如下图所示：</p>
<p></p>
<p>最后就是对工程进行相应的配置了，点击工具栏上的Configure target options按钮，以弹出的窗口中进行相应的配置，如下图所示：</p>
<p></p>
<p>至此我们一个完整的工程就创建OK啦；对于官方的程序，我们提取了Device文件夹和MF-config文件夹使用，其它的文件夹以及程序源文件都是后期创建的。接下来就是对各个部分进行代码编写了。</p>
<p> </p>
<p><span style="color:#c0392b;"><strong>程序就的大体功能就是创建LED任务，每间隔250ms闪烁一次，可以通过SHELL命令来控制时行闪烁和停止闪烁；创建KEY任务，进行按键识别，并打印出相应的按键事件/状态；使用LPTIM32作为TASK的定时器，写成任务的调度；通过LPUART0作为SHELL的调试接口，并进行SHELL程序移植；</strong></span></p>
