style="font-size:18px;">1、采用瑞萨的R7FA2E1A72DFL作为电子时钟的主控芯片；</span></p> <p><span style="font-size:18px;">2、采用一个四位0.56寸共阴极数码管用来显示时间；</span></p> <p><span style="font-size:18px;">3、通过DHT11温湿度传感器进行环境温度采集；</span></p> <p><span style="font-size:18px;">4、采用四个按键进行时钟设置；</span></p> <p><span style="font-size:18px;">5、引出一路复位按键、串口电路、SWD下载电路，方便下载调试；</span></p> <p><span style="font-size:18px;">6、瑞萨芯片集成了触摸引脚，引出一路触摸引脚出来用来作为触摸按钮使用（本是用来做为温度和湿度的切换按键的，但由于没有最新版的J-LINK调试器，所以这个功能暂时缺省了）；</span></p> <p><span style="font-size:18px;">7、通过无源蜂鸣器作为时间到达提示；</span></p> <p><span style="font-size:18px;">8、通过AO3401A+1N5819二极管组成双电源自动切换电路；</span></p> <p><span style="font-size:18px;">9、使用TP4056电池充电管理芯片，设置600mA的充电电流来给锂电池充电</span>。</p> <p class="paragraph

上电前应先目检有无虚焊现象，用万用表先测量一下无有短路故障再接通电源；</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;"><span style="font-size:18px;color:#e03e2d;">4.2 程序烧录口的连接方式是：USB转TTL线的RXD端接板子的TXD端，TXD端接板子的RXD端（简单来说就是发送和接收两边要交叉接线，不然会下载失败）。</span></p> <p class="paragraph text-align-type-left pap-line-1.3

style="font-size:18px;">由于瑞萨芯⽚是最近才出的芯⽚，所以旧版的J-Link软件不⼀定⽀持，</span><span style="color:#000000;font-size:18px;">在线仿真调试请使用J-LINK V9以上的仿真器，我手头上就有个V8的试过了确实连接不上，所以没法调试触摸按键部分内容，因此触摸按键的功能并没有用上；</span></p> <p class="document"><span style="color:#000000;font-size:18px;">2、程序烧录使用官方提供的Renesas Flash Programmer，如果没有J-LINK仿真器，可选使用串口烧录方式（常用的CH340）。</span></p> <p class="document"><span style="font-size:18px;">3、由于本人是初次使用这款MCU，加之不是搞软件的，所以对软件相关的库函数不是太清楚用法，只能把部分我能理解的都做了注释，适合初学者参照并共同提高。以下是部分软件的截图，仅供参考</span></p> <p class="document"><img
