<hr class="horizontal-splitline normal-bold-2">
<p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt">1、采用瑞萨的R7FA2E1A72DFL作为电子时钟的主控芯片;</p>
<p>2、采用一个四位0.56寸共阴极数码管用来显示时间;</p>
<p>3、通过DHT11温湿度传感器进行环境温度采集;</p>
<p>4、采用四个按键进行时钟设置;</p>
<p>5、引出一路复位按键、串口电路、SWD下载电路,方便下载调试;</p>
<p>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);</p>
<p>7、通过无源蜂鸣器作为时间重置提示;</p>

<p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt">4、注意事项</p>
<p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt">4.1 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;</p>
<p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt">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)。</p>

<hr class="horizontal-splitline normal-bold-2">
<p class="document">1、程序的开发以及编译调试使用瑞萨官方提供的e2studio,由于瑞萨芯⽚是最近才出的芯⽚,在线仿真调试请使用J-LINK V9以上的仿真器;</p>
<p class="document">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)。</p>
