The microcontroller P1 switch controls the lower four-bit water lamp

The P1 switch controls the low four-bit running water light. The speed is a bit fast, so adjust it yourself. There are notes.

The microcontroller source program is as follows:

#include

#define led P1 //Can be changed to other ports

void delay(int x);

void left(int x);

void right(int x);

void flash1(int x);

void flash2(int x);

void delay(int x) //delay function 1ms (approximately)

{int i;

while(x)

{

  for(i=0;i<125;i++);

  x--;

}

}

void left(int x) //From P1^3 to P1^0 (I call it left shift)

{int i,j;

while(x)

  {for(i=0;i<3;i++) // loop 3 times

   {led=0xfe;                  

    delay(50); //Each light is on for 50ms

    for(j=0;j<3;j++) //4 digits in total

     {

      led=led<<1|0xf1;

      delay(50);

     }

   }

   x--;

}

}

void right(int x) //From the lowest bit to the highest bit (I call it right shift)

{int i,j;

while(x) //Others are the same as left shift

  {for(i=0;i<3;i++)

   { led=0xf7;

     delay(50);

     for(j=0;j<3;j++)

     {

      led=led>>1|0xf8;

      delay(50);

     }

   }

  x--;

}

}

void flash1(int x) //Four-bit full flash (can be changed in many ways)

{int i;

while(x)

{led=0xf0;

  delay(100); //lights up for 100ms each time

  for(i=0;i<1;i++) //You can change the number of loops

   {

    led=~led|0xf0; //shield the upper four bits

    delay(100);

   }

   x--;

}

}

void flash2(int x) // flash every other bit (full flash change)

{int i;

while(x) //Basically the same as full flash

{led=0xf5;

  delay(100);

  for(i=0;i<1;i++)

  {

   led=~led|0xf0;

   delay(100);

  }

  x--;

}

}

main()

{while(1)

{led=0xff;

switch(led) //When all lights are off, multiple buttons will not work when pressed at the same time;

   {case 0xef :{left(2);}break; //Press P1^4 to shift left and change the number of loops

    case 0xdf :{right(2);}break; //Press P1^5 to move right

    case 0xbf :{flash1(2);}break;//Press P1^6 to execute full flash

    case 0x7f :{flash2(2);}break;//Press P1^7 to execute full flash change

        default:{led=0xff;}

   }

}

}
