[Kunal]

Hello,

Will u please help me to make 10 min dealy programing for 8051??

and if there is any possiblity to make 10 min delay? if yes then help me to make code for that….

[dagakshay]

do you know how to make 1 second delay???

 

 

for (j=0;j<10;j++)     // this loop wil provide you 10 min delay

  {

   for(i=0;i<60;i++)     // it will porvide you 1 min delay

     // make a dealy for 1 sec (write its code);

  }

MOV TMOD,#10

 

REPT:MOV RO,#28

 

BACK:MOV TL1,#0

            MOV TH1,#0

            SETB TR1

 

AGAIN: JNB TF1,AGAIN

              CLR TR1

              CLR TF1

               DJNZ RO,BACK

             SJMP REPT

 

 

 

 

THIS WILL BEFORE UC HAVING 22 MHZ FREQUENCY…. U CAN INCREASE THE NUMBER OF REPITION AT REG R0, OT GET UR DESIRED DELAY

Thank you very very much for your response.

 

I want to ask you can we make delay for 1hour in programing????

 

And if possible then would you help me to make it ?

I suggest you to make use of timer interrupt instead of using big loops if you want a delay of 1 hour

[SaLMAN Ahmed Khan]

yes i agree romel with you 

[romel emperado]

just search some tut in the net about timer interrupt. im sure you’ll fine some/..
