1, first in the proteus draw a simulation diagram to facilitate the simulation program
2, the following to write a program to write the first function
3, according to their own drawings in the proteus, define the pins according to your schematic
Sbit p0=P1^0;
Sbit p1=P1^1;
Sbit p2=P1^2;
Sbit p3=P1^3;
Sbit p4=P1^4;
Sbit p5=P1^5;
Sbit p6=P1^6;
Sbit p7=P1^7;
4, then write a delay function to adjust the time delay time of the water lamp to define
Void mdelay(unsigned int t)
{
Unsigned char n;
For(;t"0;t--)
For(n=0;n"125;n++)
{;}
}
5, the following is the main function, including the repeated circulation of the water lamp and the direction of the j water lamp
6, check no error, compile it. It can be simulated
