در این مثال led های متصل به پرت p1 تراشه aduc841 چشمک می زند

/* BLINKY.C - LED Flasher for the Keil MCBx51 Evaluation Board with 80C51 device*/

#include <REG51F.H>
#include <ADUC841.H>

// When you have enabled the option Stop Program Execution with Serial
// Interrupt, the Monitor-51 uses the serial interrupt of the UART.
// It is therefore required to reserve the memory locations for the interrupt
// vector. You can do this by adding one of the following code lines:

// char code reserve [3] _at_ 0x23; // when using on-chip UART for communication
// char code reserve [3] _at_ 0x3; // when using off-chip UART for communication

void wait (void) { /* wait function */
; /* only to delay for LED flashes */
}

void main (void) {
unsigned int i; /* Delay var */
unsigned char j; /* LED var */

while (1) { /* Loop forever */
for (j=0x01; j< 0x80; j<<=1) { /* Blink LED 0, 1, 2, 3, 4, 5, 6 */
P1 = j; /* Output to LED Port */
for (i = 0; i < 10000; i++) { /* Delay for 10000 Counts */
wait (); /* call wait function */
}
}

for (j=0x80; j> 0x01; j>>=1) { /* Blink LED 6, 5, 4, 3, 2, 1 */
P1 = j; /* Output to LED Port */
for (i = 0; i < 10000; i++) { /* Delay for 10000 Counts */
wait (); /* call wait function */
}
}
}
