Nice to meet you aagin Mr.Erik,we have met in Keil fourms and your answers were valuable.
I've read about it from Mazidi's Book about Microcontrollers, In the chapter of the timers(chapter 9) he mentioned that you can use the counter mode of the timer by feeding an external squarewave of 60 Hz frequency into the timer,and the program he has written will generate seconds minutes and houres out of this input frequency. but the problem that i didn't find the code he mentioned in the appendix
what's your opinion.
