<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;">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;">参照2023暑期训练营电子时钟案例，实现时钟、温度、湿度三种显示模式。</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;">可通过按键修改小时和分钟两个字段调整时间</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;">供电有USB 5V和内置18650电池（带保护电路）两种方式。</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;">HEX烧录文件已上传（2023-08-07）</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto

style="font-size:18px;"><strong>2、硬件部分</strong></span></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;">原理图大部分参照官方案例，为了扩大显示部分，把0.56寸的数码管改为手搓的大号LED，显示面积差不多是原来的四倍。</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/IxaHPh1syRfo0tm5yrSlwnCwdHBIRbU5WNHmO96o.png" alt="" width="1000" height="512"></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;"> </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;">PCB的大小为10*5CM，把显示用的LED全部放置在顶层，所以底层得扛下其他元件的放置。</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;">加上底层又是用来放电池，占去半壁江山，尽可能的采用贴片元件，或者直插件改为贴片焊接。</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/45xuycjLan6Rl02CJVpxQVaGX3Xh2MtdndWi3YeL.gif" alt="" width="1000" height="501"></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;"> </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;">刚开始打算挑战两层板，结果还是自己太天真，四层板拉线也费了不少功夫。</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;"><span style="color:#95a5a6;font-size:14px;"><img

pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">最费劲的是找个合适的按键，逛了整个商城，又要贴片，又要长柄，好像没有。</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;">最后只能用这个直插的开关做一些改动，硬生生的改为贴片焊接。</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;">如果不修改封装用直插的话，从3D预览可以看到是穿到LED上，真是会给自己制造麻烦的活，啊不，我只是喜欢挑战。</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/cOPBfxt3e1ulBfKpZj0oO3nW9DIjLBL9YjABL6lW.jpeg" alt="" width="1000" height="297"></p> <p

src="//image.lceda.cn/pullimage/CdoFeHehFGptJWtrSIMe1VjlrA17AdFt7UAL9S9O.gif" alt="" width="1000" height="632"></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;">PCB布局一般没什么大问题，唯一要注意充电芯片TP4056的散热焊盘，在铺铜后需要加上实心填充以加强散热。</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;">光靠十字连接导热是不可能的，这都是经验教训。</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/MCQVXJIyhmbd6mtD4k4KotjqFNv8Oaxpz6rFMXAR.png" alt="" width="1000" height="449"></p> <p

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、软件部分</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;">程序依照瑞萨肖工的教学视频进行编写</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.改动部分为LED驱动，段选和位选IO都需要高电平才能点亮LED。</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;">时钟冒号由单独两个IO驱动，方便在显示温度和湿度时用上。</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;"> </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;">需要把原来的SMG_DP_OPEN和SMG_DP_CLOSE折分为D1和D2两行再OPEN和CLOSE</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;">SMG_1234因为方便拉线改为SMG4321反向顺序，可用里面的ceshi()函数来确定第一位是不是在左边。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt

pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">原先用来切换温湿度显示，后面改为按键4切换。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt
