<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">收到开发板有些时日了，因为年尾了，手头上的项目有点紧，赶紧抽空对开发板来一个第一轮的简单开箱上电评测。</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"> </p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">开发板的外包装档次还是比较高的，值得永久珍藏。</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">再来看主角的全貌，PCB布板干净整洁，自带仿真器，资源丰富，有LED、按键、Nand Flash（一开始没找到，原来藏在LCD下面）、LCD、USB、EEPROM、数字音频模块等，还引出了所有的IO口，作为一块开发板，物尽其用。</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">首先打开兆易官网的链接找到GD32E5的资料</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线"><a data-darkreader-inline-color="" href="http://www.gd32mcu.com/cn/download/0?kw=GD32E5" style="color: rgb(5, 99, 193); text-decoration: underline; --darkreader-inline-color:#59b2fb;">http://www.gd32mcu.com/cn/download/0?kw=GD32E5</a></span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">把这些资料全部下载到电脑。MDK的包管理器里还找不到GD32E50x的包，所以先安装GD32E50x ADD-ON文件夹里的DFP文件。</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">然后就可以打开下载好的GD32E50x-Demo_Suites目录的例程</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">这里我选择了第一个GPIO_Running_LED来进行开箱测试。</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">看原理图，四个LED等分别对应的IO口是PC0、PC2、PE0、PE1</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">打开MDK的工程文件</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">可以看到工程中初始化的LED就是对应的原理图中的四个IO口，看来例程的代码都是完全匹配开发板的。然后编译运行…… 哎呀，怎么仿真出错了，噢，对了，还没有选仿真器呢！打开仿真器设置界面，怎么没有GD-LINK呢？难道是驱动没有装，但是没看到官网有提供驱动下载啊！</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">看了GD-Link的文档说明，才发现就是基于CMSIS-DAP的仿真器接口</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-indent:21.0pt; text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">仿真器上选择了CMSIS-DAP，运行，开发板上的4个LED逐个点亮然后灭掉</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"></p>
<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:等线">至此，第一轮的上电开箱评测结束，后续的会陆陆续续补上来。</span></span></p>
<p style="text-indent:21.0pt; text-align:justify"> </p>
<p>这个开发板挺好的，还带个屏幕，好好参与测评哈！期待你后续的测评帖子~</p>
<p>谢谢分享！期待后续！</p>
<p>keil提示找不到sarmv8m.dll，是版本太老的原因？请问楼主用的是什么版本的keil</p>
