<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>

<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;">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. J) (ti.com)</a> 咱就不在这搬门弄斧了。</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/DI7dZr4GxY912wZVCwTtYc6gkdZi7Ut3aLjoBW9u.png" alt="DI7dZr4GxY912wZVCwTtYc6gkdZi7Ut3aLjoBW9u.png" width="602" height="173"></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;">项目从5V电压降至3.3V,使用的芯片是RT9013-33,怎么说呢,这颗芯片很完美,而且体积可以做得很小,详细可以去小破站观看视频,有博主讲的很不错。</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/0hlSEd8xE00QTr18OxLem5LG4DDuWQqbAno6qjUl.png" alt="0hlSEd8xE00QTr18OxLem5LG4DDuWQqbAno6qjUl.png" width="377" height="163"><img src="//image.lceda.cn/pullimage/3Lll6yDEp0pMTeTt5I3UGTJjlwMusogX7HtWPUZr.png" alt="3Lll6yDEp0pMTeTt5I3UGTJjlwMusogX7HtWPUZr.png" width="177" height="164"></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;">(3)驱动板</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;">驱动接口部分没有使用像排针之类的东西,我所使用的东西为这个(如下图),为什么使用这个呢,我觉得很方便,没了。备注:驱动板的测试视频在工程附件里面</p>
