Adhic902: That is the same one I have and it stopped working about 2 weeks after I got the unit. My unit displays 00:00:80. I troubleshot the board with a scope and determined that the DS1307 chip is not working. It appears that the crystal input is defective or the crystal is defective. I am going to order a new one tomorrow and should have a new one by Monday. I'll try the new board with the current program and let you know what is going on late Monday.
I will wait for it Bob, thanks in advance.
don't we need just TX Bob in this case?
Bob can u help to set the initial time for this? i think this program need an initial time
No you would need the RX on the UART to get the data to set the time.
I just ordered the DS1307 module will be here on Tuesday not Monday.
