[sachin]

HELLO,TELL ME HOW TO CALCULATE 1 SECOND DELAY IN 8051 BY USING TIMER 16 BIT MODE HOW TO CALCULATE VALUE FOR THO AND TL0????

[Ashutosh Bhatt]

with timer in 16 bit mode u can generate max delay of 65 ms aprox. 

so u need loop to repeat the process

you set timer to count 50000 to generate delay of 50 ms

then just rotate it for 20 times in for loop so u get 20×50 = 1000 ms = 1 sec
