开启环境：
使用终端，升级并安装sdcc：
sudo apt install sdcc
安装仿真工具：
sudo apt install mcu8051ide
测试如下案例：
代码语言：javascript复制#include<8052.h>
#define LSA P1_5
#define LSB P1_6
#define LSC P1_7
#define Led P0
char brightness=0,a=0;
void EXint_Init(void);
void Delayms(unsigned int);
void EXINT0() __interrupt 0;
void main()
{
EXint_Init();
LSA=0;
LSB=0;
LSC=0;
while(1)
{
Led = 0x00;
a=brightness;
while(a--);
Led = 0xff;
a=255;
while(a--);
}
}
void EXint_Init()
{
IT0=1;
IT1=0;
// IPH=0x40;
PX1=1;
EA=1;
EX0=1;
EX1=1;
}
void Delayms(unsigned int xms)
{
unsigned int i,j;
for(i = xms;i > 0;i--)
{
for (j = 110;j > 0;j--);
}
}
void EXINT0() __interrupt 0
{
brightness ;
}
编译出现警告：
sdcc -mmcs51 led.c
将char 改为 int；（注意位置）
再次编译，一切ok。
使用如下功能，将led.ihx下载到本地连接到单片机使用即可。
