#include<reg51.h>
sbit yinjiao1 = P1 ^ 2;
sbit yinjiao2 = P2 ^ 2;
int main () {

yinjiao2 = 1;
}
}
MCU programming is a hexadecimal file, in order to generate a hex file (* .hex), we need to set the hex file before compilation

Then the last action ( how to program into the microcontroller and run ), run the program
Since the simulation is, even if there is no minimum run circuits (actual situation is not acceptable, we must minimum system )
