Hi Eng4444,
Just got home from work and see that you are still having a problem. Just a quick question. Is the ability to set the time with the 3 push buttons really critical for you to show what you have done? If not then you could go to the part of the code that starts with "SETUP PRESET:" and enter the starting time and date manually. I will look over the code here this evening and get back to you on that.
Adding the capacitors (.1uF) has nothing to do with this problem. They are part of good design practice.
Just so I understand what has happened: You programmed the micro and the system started running and time and date was being displayed. You went into the set time and date mode and it accepted your time and date changes. Then you pressed the button to send you changes to the RTC and that's when it froze.
I will look for that part of the code you sent me and compare it with Melanie's posted code. Just out of curiosity, did you copy and paste her code or did you retype the whole thing?
Let me know. Thanks!
BobK
