Hi, I am trying to perform serial communication with two AT89S52 MCs. Now the problem is that sometime everything works fine, but sometimes not. ------ Hardware Config-------- ---> RC reset circuit ---> 11.0592 MHz crystal ---> Mode 1 for serial communication with 9600 baudrate ---> Port 2 as output port at receiver side
Hardware is working fine with simple programs like LED blinking, but when it comes to serial communication, nah ..........behaves randomly.... Any suggestion will be valuable for me.
Well lets see, i will try that too.. and once again thanks to all of you for your valuable time and comments.
