font-size: 14px; background-color: #ffffff; font-family: 'arial black', sans-serif;">1、在源代码的基础上增加usart的串口通信代码，可与更多外设进行数据交互；增加该项目的可玩性，并且引出通信针脚可增加其他外设；初学者会容易复刻学习，也能在这基础上增加自己熟悉的外设，使项目更加有趣和使用。</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="color: #95a5a6;

font-size: 14px; background-color: #ffffff;">2、在usart代码中编写了usart_1~usart_4的执行代码，方便初学者调用；这样只需要在PCB中将对用的管脚引出或应用相应的外设即可，并且使用printf打印函数更加便捷。</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="color: #95a5a6;
