【Proteus仿真】51单片机串口输出实验

📌相关篇《【Proteus仿真】51单片机Blink点灯实验》🔖Proteus仿真基础实验-串口输出。🌿Proteus8.12平台🌿本实验代码基于VSM Studio，采用SDCC编译器。🌿调试串口波特率：9600🎬仿真演示：

⛳头文件使用说明

⚡第一次调用STC89.h头文件时，有可能会报错，因为安装后的SDCC自带头文件库中，有些寄存器定义有问题。可以将报错的寄存器注释掉。或者使用8052.h头文件。

🌿使用printf()函数打印调试信息，包含stdio.h头文件。

int putchar(int data1){SendData(data1);return data1;}

🌿虚拟串口监视器
