1.下载keil uVersion软件 2.安装keil5软件 3.注册keil5软件
直接下载安装就好 STM32下载地址
1.新建文件夹MyProject并在文件夹中新建CMSIS(存放内核函数及启动引导文件)，FWLIB(存放库函数)，USER（存放用户自己的函数） 2.从已安装的STM32F10x-STM32F10x_StdPeribh_Lib_V3.5.0标注库的Libraries文件夹将CMSIS中所有文件复制到新建的同名文件夹中; 从标准库中的C:\STM32F10x标准库-STM32F10x_StdPeriph_Lib_V3.5.0\STM32F10x_StdPeriph_Lib_V3.5.0\Libraries\STM32F10x_StdPeriph_Driver中的inc、src复制进FWLIB文件夹； 从C:\STM32F10x标准库-STM32F10x_StdPeriph_Lib_V3.5.0\STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Template将所有文件（主意：文件夹可以不用复制，只复制当前目录下的文件就行）复制到USER中 3.打开已安装的软件Keil uVision5，新建工程temp到MyProject下,设置项目名----选择芯片（STM32F103VE）—下一个窗口直接叉掉就行， 4.使用软件自带的工具导入文件 在project target中填写你的项目名比如temp，在group中添加CMSIS,FWLIB/src,USER,STARTUP,在files文件中点击add file添加对应的文件 main.c代码

1.打开keil，新建一个以AT89C51为芯片的项目
2.新建一个C语言程序
#include<reg51.h> sbit p1_0=P1^0; sbit p1_7=P1^7; main() { int i; while(1) { p1_0=0; do{}while(p1_7=1); do{}while(p1_7=0); p1_0=1; for(i=0;i<=255;i++){}; } }3.设置参数，编译整个项目，并生成.hex文件
5.打开proteus软件，并画一个电路图
7.导入.hex文件
8.仿真结果
在此过程中若有问题欢迎指出。
