一、创建一个Keil代码工程
1、在电脑F盘(哪个盘可以随意选择)上创建项目工程文件夹Template
2、在Template文件中,创建一个main.c文件
3、进入keil主页面,工具栏project---->New uVision project---->选则第一步的工程文件夹位置-->输入工程名字
4、选择芯片类型AT89c52,点击ok
5、会提示是否拷贝STARTUP.A51,选择是
6、生成了工程目录--->在工程目录Source Group1 上右键鼠标--->add Exiting file Source Group1..
7、加载之前新创建的main.c文件,点击Add,再点击Close
8、看见keil左侧,已经加载出main.c的文件,然后在main.c文件中编写代码
#include "reg52.h" //sbit ledOne = P3^7; sbit led1 = P3^7; sbit led2 = P3^6;
void main() { led1 = 0; led2 = 0; while(1); }
9、怎么样编写的C语言代码,在C51中也能认出来
10、点击Rebuild,进行编译
11、 打开项目工程文件夹Template,可看到moban.hex程序(hex程序是单片机可运行的程序)
二、单片机和电脑连接
1、安装串口程序——ch341ser.exe
2、把单片机插入到电脑上,我的单片机是用tapyc线连接的
3、打开设备管理器:查看单片机和电脑是否连接成功,如下是连接成功了
三、把代码烧录到单片机
1、打开stc-isp-15xx-v6.87D.exe这个软件
2、先选择单片机型号,然后对一下串口号,是否和电脑上的串口号一致,然后打开程序文件
3、打开程序文件
4、点击下载编程
5、等待5s后,按单片机的打开/关闭开关,把单片机重新上电,然后看到操作成功,说明已经烧录成功了
6、单片机效果演示,两个小灯亮了
