<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;">51单片机学习板,可以方便大家学习STC51单片机,而且成本还很低,仅需二三十元,还可以锻炼你的焊工呢 =)</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 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;">首次公开,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 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;">核心为STC89C52RC,其他根据需要焊接</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 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;">这个项目集成了STC89C52RC单片机的系统板(当然你也可以装STC89C516RD+,程序空间更大。)在芯片上建议焊接ZIF插座,方便换芯片,</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;">.还增加了一些外围的模块:1602液晶显示,EEPROM,6位数码管,LED流水灯,蜂鸣器模块,4x4矩阵键盘,1x4独立键盘,温度测量 1602的排针上可以焊接排母,方便插装1602 单片机的引脚全部引出,方便大家进行拓展。关于各个功能的IO口,请大家自行查看原理图和PCB。 </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;">注意,本工程未有USB转串口模块,下载程序请自备模块,电路板上预留了下载接口,USB-TTL的VCC接烧录排针的VCC,GND接GND,USB-TTL的RXD接到单片机的P3.1引脚,USB-TTL的TXD接到单片机的P3.0引脚。电源不要接反,使用5V供电,若要烧录程序,要给单片机冷启动才能烧录。</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;">还有,使用1602液晶时,1602是在学习板的内部的,不可插反,不然1602会烧坏!!</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;">5、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;">给51单片机编写程序,需要用到KEIL C51,下载程序需要STC-ISP,软件请自行在网上下载。</p>
