<div class="document"> <h3 class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">前言</h3> <p>说一下为什么会做这一个东西，怎么说呢，有点遗憾，第十七届智能车因为种种原因没有参加，所以趁着训练营的机会，去弥补一下，另外一个目的就是测试一下这一款芯片，毕竟是国产的嘛，老用国外的也不太好，是吧，嗯，就这样。对了当时一共买了两款芯片，一个是N32G452CBL7，一个是N32G430C8L7，感觉都很nice。</p> <p><img src="//image.lceda.cn/pullimage/WxYMZgjdaKCA9GcHheSssJSN9hO1ylW46INitznm.png" alt="WxYMZgjdaKCA9GcHheSssJSN9hO1ylW46INitznm.png" width="538" height="99"><img src="//image.lceda.cn/pullimage/6PbPlGyoSInO0kQP8Kvk1dfDaQfjapWA7ylteizw.png" alt="6PbPlGyoSInO0kQP8Kvk1dfDaQfjapWA7ylteizw.png"></p> <h3 class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">1、项目功能介绍</h3> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">电磁，物理概念之一，是物质所表现的电性和磁性的统称。如电磁感应、电磁波等等。电磁是丹麦科学家奥斯特发现的。电磁现象产生的原因在于电荷运动产生波动，形成磁场，因此所有的电磁现象都离不开电场。电磁学是研究电场和磁场的相互作用现象，及其规律和应用的物理学分支学科。麦克斯韦关于变化电场产生磁场的假设，奠定了电磁学的整个理论体系，发展了对现代文明起重大影响的电工和电子技术，深刻地影响着人们认识物质世界的思想。本项目“基于N32G430C8L7的电磁寻迹小车”是基于LC电路去检测磁感线从而获得磁感应强度，用来达到小车的寻迹功能。</p> <h3 class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">2、项目属性</h3> <p>项目首次公开，且为原创</p> <h3 class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">3、开源协议</h3> <p>项目核心功能开源80%以上</p> <h3 class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">4、硬件部分</h3> <p>（1）核心板</p> <p>①电源电路</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><img src="//image.lceda.cn/pullimage/ewFTlqeNA2Pr1mFYH0H0eyb0f55E9FptLcnsv0gm.png" alt="ewFTlqeNA2Pr1mFYH0H0eyb0f55E9FptLcnsv0gm.png" width="445" height="331"></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">项目使用了最为经典的1117稳压芯片，有些人说为什么不用AMS1117呢，它更便宜呀，对于为什么采用SPX1117这款芯片，作出以下解释，首先我们来看这两张图</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><img src="//image.lceda.cn/pullimage/Pp1hfxmVfj1ZmUEt4oOUnh1as8HVyJ8ynrScqtNF.png" alt="Pp1hfxmVfj1ZmUEt4oOUnh1as8HVyJ8ynrScqtNF.png" width="327" height="128"><img src="//image.lceda.cn/pullimage/xoEgV2aX3FwWdosOnrGRnB2mKYl5DW3aasu1bSwr.png" alt="xoEgV2aX3FwWdosOnrGRnB2mKYl5DW3aasu1bSwr.png" width="271" height="131"></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">有图我们观察到Vin（Max）变了，一个是20V一个是15V，由于本项目的供电电源为7.2V/12V锂电池进行供电，所以本着短路或其它不可逆转的原因，所以选择了较为贵一点的SPX1117（其实也没有啦，因为本人的板子从来没有烧过，你说我这个人可不可气）。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">性能测试，由于当时用示波器测的数据没有保留，所以截取了官方给的数据手册（如下图），输出波形曲线很理想，怎么说呢，我觉得够用。另外给做硬件测试的小伙伴一个建议，示波器真的很有用。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><img src="//image.lceda.cn/pullimage/Ve87n8aKyMa3E0Jn4pPwCzTJgzA1Nlb8hmMFGCtH.png" alt="Ve87n8aKyMa3E0Jn4pPwCzTJgzA1Nlb8hmMFGCtH.png" width="455" height="155"><img src="//image.lceda.cn/pullimage/L3nsbxR9HvsKWTtnk6B2th2Kg8fcIGw3d7jdSzvu.jpeg" alt="L3nsbxR9HvsKWTtnk6B2th2Kg8fcIGw3d7jdSzvu.jpeg" width="180" height="135"></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">（2）子板</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">①电源电路</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><img src="//image.lceda.cn/pullimage/Y9k9FXuskkCt6rzEzQuIvhsYl8sNISzHNH8v5zFg.png" alt="Y9k9FXuskkCt6rzEzQuIvhsYl8sNISzHNH8v5zFg.png" width="662" height="262"><img src="//image.lceda.cn/pullimage/UvVAvG4DhuexH9zdAW4SWnXyiOakpRvgFZHBzOBj.png" alt="UvVAvG4DhuexH9zdAW4SWnXyiOakpRvgFZHBzOBj.png" width="432" height="264"></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">对于5V电路，相信对于大部分硬件玩家都很熟悉，LM2940俺觉得基本上都用过，说一下我为什么用它呢，有句话说得好“买贵不买对”，这价格真的很nice，开玩笑开玩笑，首先是基本介绍，嗯……还是略吧，43页的数据手册基本上什么都有，感兴趣的可以去看一下，链接如下：<a href="https://www.ti.com/cn/lit/ds/symlink/lm2940-n.pdf?ts=1662787435037" target="_blank">LM2940x 1-A Low Dropout Regulator datasheet (Rev.

<p>不得不说博主在选料上有点外行，AMS1117和SPX1117选型关键点根本不是耐压，同封装LDO你就是上15V，看的也是耗散功率，而不是耐压。SPX1117的PSRR比AMS1117要好的多，而且前者还可以用陶瓷电容，后者得用钽电容或者大容量电解电容这种ESR稍高的电容器才能保证环路稳定。</p>
