基于STM32F401RE开发板的X-NUCLEO-IKS01A3传感器测试之一 STTS751温度传感器测试

<div class='showpostmsg'><p style="text-align:justify">&nbsp; &nbsp; <span style="font-size:10.5pt"><span style="font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;"><span style="font-size:12.0pt"><span style="font-family:宋体">收到</span></span><span style="font-size:12.0pt">X-NUCLEO-IKS01A3</span><span style="font-size:12.0pt"><span style="font-family:宋体">套件后,一直都在查找、下载资料,阅读相关的手册和分析代码。我使用的是</span></span><span style="font-size:12.0pt">STM32F401RE</span><span style="font-size:12.0pt"><span style="font-family:宋体">开发板,在</span></span><span style="font-size:12.0pt">Keil V5.28</span><span style="font-size:12.0pt"><span style="font-family:宋体">平台下测试,经过几天的反复测试,</span></span><span style="font-size:12.0pt">STTS751</span><span style="font-size:12.0pt"><span style="font-family:宋体">温度传感器终于测试通过了。为了测试时更直观,我还添加了</span></span><span style="font-size:12.0pt">LCD5110</span><span style="font-size:12.0pt"><span style="font-family:宋体">作为显示用。下面详细介绍测试过程。</span></span></span></span></p>

<p style="text-align:justify">&nbsp;</p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;"><span style="font-size:12.0pt"><span style="font-family:宋体">一、硬件连接</span></span></span></span></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;"><span style="font-size:12.0pt"><span style="font-family:宋体">&nbsp; &nbsp; 开始测试之前,首先是考虑如何接线。起初我按照习惯,在下载的资料中查找传感器板上的接线定义,以便用杜邦线与开发板连接。后来才知道两块板子引脚都是遵循了</span></span><span style="font-size:12.0pt">Arduino UNO R3</span><span style="font-size:12.0pt"><span style="font-family:宋体">规范,只要直接插上就行。难怪传感器板子上面有个凹口,正好是留给操作开发板上按钮和观察</span></span><span style="font-size:12.0pt">LED</span><span style="font-size:12.0pt"><span style="font-family:宋体">灯的,起初拿到传感器板子时我还纳闷为何要做成如此不规则的形状呢。</span></span></span></span></p>

<p style="text-align:justify"></p>

<p style="text-align:justify"><span style="font-size:10.5pt"><span style="font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;"><span style="font-size:12.0pt"><span style="font-family:宋体">&nbsp; &nbsp; 插上传感器板子之后,凹口正对着开发板上的按钮和</span></span><span style="font-size:12.0pt">LED</span><span style="font-size:12.0pt"><span style="font-family:宋体">灯:</span></span></span></span></p>

<p style="text-align:justify">&nbsp; &nbsp;&nbsp;<span style="font-size:10.5pt"><span style="font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;"><span style="font-size:12.0pt"><span style="font-family:宋体">我从&ldquo;</span></span><span style="font-size:12.0pt">ST_Open_MEMS</span><span style="font-size:12.0pt"><span style="font-family:宋体">教程&rdquo;中看到首先要在线接受软件许可使用协议后,取得开发板密钥后方能解锁使用(如下图所示),弄得我到处去找在线接受许可的界面,好不容易找到一个界面,可点击之后老半天没有反映。然后又看到需要一个&ldquo;</span></span><span style="font-size:12.0pt">Sensor Fusion GUI</span><span style="font-size:12.0pt"><span style="font-family:宋体">&rdquo;软件来配合调试,可找了许久也没有下载到此软件。最后还是决定自己添加一块</span></span><span style="font-size:12.0pt">LCD5110</span><span style="font-size:12.0pt"><span style="font-family:宋体">显示屏来作测试过程的显示用。</span></span></span></span></p>

<p>1、顶楼上说过,直接插在开发板上就行。</p>

<p>2、开发板有配套的damo,自己只要将数值显示在屏幕上就行。</p>

<p>但是我用的扩展板和这个不完全一样,而且他没有文件</p><br/><p></p><br/>

<p>我的这块板子传感器是I2C通讯的,我用厂家的damo,具体的通讯协议我没有深究。</p>
