Software Delay Functions

Explanation

This code listing shows how to create a 1ms delay in the Arduino board. Greater delays can be created with the other function.

/* Delay function that create a 1 ms delay. It is optimized for a 16 Mhz clock
 * clock cycle. Do not forget that it is only a software delay function        */
void delay_ms(void){
    int i;
    for(i=880u; i != 0; i--);
}
 
/* Function to create bigger delays. Uses delay_ms as the basic function        */
void delay(uint8_t tms){
    uint8_t    i;
    for(i = tms; i != 0; i--){
        delay_ms();
    }
}
