  2. Code for accurate 1 second delay function


Code for accurate 1 second delay function

;======================= DELAY 1 SEC ================ 

DELAY_1S DELAY_1S:

MOV r7,#1    ;Value of R7=no. of second delay for 12Mhz(1.0003S ACCURATE)
D1S0:   MOV r6,#0ffh
D1S1:   MOV  r5,#245
D1S2:   NOP
        NOP
        NOP
        NOP
        NOP
        NOP

        NOP
        DJNZ r5,D1S2
        DJNZ r6,D1S1
        DJNZ r7,D1S0
        RET

Note : You can chance the value of r7 to get different value of delay. The delay function can be use in many different processors / microcontrollers (ATMEL, PIC microchip, Dallas, NXN Philips...) . Also not that is function is code for 12Mhz frequency, for different frequency, different value of register will be need to calculate.
