Microcontroller Learning Notes (II) - Simple Applet-EEWORLD

Collect

Today I got a few simple programs for the microcontroller:

Delay program:

void Delay(unsigned int xx) //Input xx: ms

{

while(xx--)

{

Delay1ms();

}

void Delay1ms() //@11.0592MHz 1ms

{

unsigned char i, j;

_nop_();

i = 11;

j = 190;

{

while (--j);

} while (--i);

}

Flowing lights program:

#include

int main()

{

p1 = 0xfe;

while(1)

{

p1 = _crol_(p1, 1);

Delay(500);

}

return 0;

}

Buzzer program:

void BEEP_ON() //Buzzer on, duration: 500ms,

{

sbit beep = p2 ^ 3;

beep = 0; //Buzzer on

Delay(500); //Delay

beep = 1; //Buzzer off

}
