<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;"><span style="color: #95a5a6; font-size: 14px;"> </span>此项目是为辅助汽车通讯电子行业人员调试LIN通讯逻辑和测试产品而设计。</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;"> 在汽车电子通讯行业,用到LIN通讯的功能模块可能包括雨量传感器、雨刮开关、前大灯、座椅位置马达、压力传感器、车门的后视镜、窗户控制等这些对通讯速度要求不高(和CAN通讯相比)的产品。车厂需要根据不同使用场景协调所有车身传感器和执行器运行不同逻辑,在整车设计验证阶段,车厂会分解不同的任务和通讯信号,然后下发给对应的供应商,供应商需要根据上下节点通讯设备的理论设计来针对性调试自己家设备的逻辑,而此时,就会用到LIN通讯相关的调试设备来模拟上下节点的LIN命令。</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;"> 本项目旨在提供一种对于调试和测试LIN设备较为方便和友好的嵌入式设备,且设计和生产成本控制较低。设备的方便性体现在设备小型化,手持即可,并且集成12V电池可充电设计。友好性体现在有直观的按键和屏幕显示进行交互,使用简单,学习成本很低,对于需要频繁调试LIN通讯逻辑的工作效率很高。</p>

<h4 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;"> 4.1、本设备的原理图,PCB,3D外壳和面板全部用立创EDA设计,硬件设定的需求如下:</h4>
<ol>
<li style="list-style-type: none;">
<ol>
<li style="list-style-type: none;">
<ol style="list-style-type: lower-alpha;">
<li 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;">支持LIN2.1通讯功能;</li>
<li>设备在室内使用12V电源外部供电,保证全天可靠工作;</li>
<li 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;">设备在室外使用电池续航4小时,电池既给本身供电,也给从机供电,工作功耗平均大概4.5W(12V,375mA);</li>
<li 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ADC分压电路,设备自己能检测正极和负极之间电压;</li>
<li 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;">有屏幕显示设备主机和从机信号状态;</li>
<li 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;">有按键能方便切换自身信号状态;</li>
<li>能在2个月内的业余时间完成,因为我7月底才开始有想法设计这个项目,近期工作出差又较多;</li>
</ol>
</li>
</ol>
</li>
</ol>
<p> 考虑到开发周期并不充裕,还要给软件设计留有时间,所以单元电路基本都是采用几种较为成熟的方案来验证实际效果是否可行。目前电路和PCB设计验证过程修改过几次,下面我将遇到过的问题,解决方法和需要注意的地方介绍一下。</p>
<h4 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;"> 4.2、电路主要为以下几个部分:</h4>
<h4 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;"> 4.2.1、供电电路设计,12V转5V,5V转3.3V电路如下图:</h4>
<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;"> 此部分电路变更过2次,第1次直接使用12V转3.3V的AMS1117,验证后发现发烫比预想严重,手摸上去无法承受的那种烫,手边没有温度检测仪,没测具体温度,设计之前也大概了解LDO在压差较大并且带有较大负载的情况下会发热,但没想到100多毫安就能这么烫,所以后续改成两次降压。</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;"> 第2次电路和下面截图这种方案唯一的区别就是12V转5V芯片使用的也是AMS1117系列,LDO在PCB位置打孔和开窗加快散热后,温度已经能接受,但搜到的几款AMS1117输入电压要求都在18V以下,本设备常规使用时供电电压在9V~16V,但考虑到设备在极端测试时,会有16V到20V供电的场景,所以换成如图中CJ7805。最大输入电压可以到35V,在PCB上增加LDO周围铺铜填充面积,同样打孔和开窗后,温度可以接受,手摸上去可以感受到发热,但不至于烫手。</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;"> 图中可以看到有两路保险丝,是因为在第一版PCB到手后调试过程发生过短路,板子上LDO,MCU和LIN等芯片全部烧毁,为避免之后在发生此类情况,增加了这两路保险,第一路是保险丝是单板调试时使用,能承受最大电压16V,保持电流100mA 跳闸电流250mA,第二路保险丝是全场景工作时使用,能承受最大电压60V,保持电流500mA,跳闸电流1A。增加的保险丝也确实在我后来的几次调试中发挥了重要作用,所以就保留了下来,根据实际负载情况,用跳线帽选择其中一路。</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/HeXYO8J0pFettgaJVNphMGmzbkL52GCnuTvvZfBM.png" width="894" height="237"></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/XS2kPMg2xA81St97yddFjyTCNBoigu2Q87IGlsRi.png"></p>
<h4 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;"> 4.2.2、LIN通讯电路设计如下图:</h4>
<p> 参照芯片手册典型应用设计,其中2号SLP_N引脚用来控制芯片休眠和唤醒,高电平正常工作模式,低电平休眠,指导手册里SLP_N和MCU引脚相连,这样可以控制LIN芯片休眠和唤醒。本项目设备开机就是要使用LIN通讯,所以没有LIN芯片休眠需求,就接高电平了,注意不能悬空。</p>
<p><img src="//image.lceda.cn/pullimage/jd4IQ6zgEg1lATuspkCt5Fe5ssZWwZtHUQRfuetp.png"></p>
<h4 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;"> 4.2.3、编码旋钮和轻触按键电路设计如下图:</h4>
<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;"> 目前设备只用到轻触按键,编码旋钮是为了给以后其他交互需求预留。原理图很简单,这里需要注意的是,选择MCU检测按键的引脚时,一定要确认对应引脚是支持输入模式的。</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/jzD74JrcUKSGJmJssHijxnRd2xAJSg8XojQoTzM6.png"></p>
<h4 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;"> 4.2.4、LCD屏幕接口电路如下图4.1:</h4>
<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;"> 图中LCD底座接口为了使用立创商城编号C5329587的显示屏,商城截图如图4.2,最后几个库存被我全买了,不知道商城多久会补货,淘宝上也有线序和通讯型号一样的LCD可以选购,插到PCB上显示功能正常,但是尺寸有差异,和本项目一起设计的3D外壳可能会不匹配。</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;"> 此部分电路设计需要注意的是LCD是3.3V供电,LCD的通讯引脚支持的最大电压也是3.3V,所以MCU的供电也要选择3.3V。</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;"> 至于图中LCD右侧支撑件是为了保证屏幕安装到PCB上面后,两端高度一样,所以在PCB上对应位置放置一个没有任何连接的接插件。这里需要注意的是,选择MCU与LCD通讯的引脚时,一定要确认引脚是支持输出模式的。</p>

<p> 图中充放电管理IC用的是CM1033-DS,品牌深圳iCM(创芯微),立创<span class="c9a9a9a">商品编号:</span> <span class="relative">C2685513。是一款专用于 3 串锂/铁电池或聚合物电池包的充放电保护芯片,串联3节1500mAH以上的18650电池,能满足设备续航需求。图中网络标识12V和12V_02连接是一个滑动开关,上述LDO电路中有具体连接方式,LIN通讯电路里也有用到。</span></p>

<h4 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;"> 4.2.6、MCU主控选用瑞萨RL78系列型号R5F10BGGLFB:</h4>
<p>此型号是瑞萨RL78/F13系列的车规级芯片,立创商城目前没有此型号,但是有RL78/G13通用系列,内核和开发工具都是通用的,由于我近期业余时间不多,软件代码还没有移植到其他型号。此芯片也是本项目唯一1个没有在立创商城购买的器件。</p>
<p><img src="//image.lceda.cn/pullimage/Do1tHhfciHlfUSnAINs0ygujZB8fFVkhEt3qHm5m.png"></p>
<h4 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;"> 4.2.7、ADC检测电路如下图:</h4>
<p>实际电池正极12V_02和GND之间的电压=VOLTAG*15,受限于分压电阻精度和电源电压波动,最终值预计会有0.3V的误差。作为辅助设备,此功能只是用来评估设备大概电池电量,已经够用。 </p>

<p> LCD驱动基础代码资料,可以从本屏幕的厂家 <span class="fw-b inline-block brand-buried"><a title="HS(汉昇)" href="https://list.szlcsc.com/brand/13150.html" target="_blank">HS(汉昇)</a></span>得到,此屏幕的立创商品编号C5329587。从网上其他论坛或者网购平台也容易下载到此屏幕用到的ST7789芯片资料。下面对应用层做一些说明:</p>
<p> 刷新屏幕数据是很耗时的,本项目的芯片IO刷新一次整个屏幕数据(320*240),大概需要1.3秒,所以上电后先把固定显示的内容刷新出来,然后只刷新实时变动的参数,这也是普遍做法。为了保证任务被调用时持续阻塞时间不能超过10毫秒,刷新完其中一个参数就先退出本任务,执行完其他任务再刷新下一个参数,以此类推。</p>
<p> LCD固定显示内容如下:</p>
