RTC - code not working - Mel's example
Ok so now I've sussed out why the RTC module wasn't working, I've used Mel's code to test the RTC and have stumbled into a problem which for the life of me can't get working.
When powered up it displays the time on the 1st line and date on the second (incidentally it seems to skip the pre-sets in the code and use the date set in a previous bit of code used to test the module). The code responds to RA5 going low and jumps to set mode. However the LCD just sits there at Set Mode with the 12HR / 24HR overwriting itself every half a second. Pressing any of the buttons on PORT A has no affect, and the code doesn't jump back to normal clock mode if left for several seconds with out input.
Your help would be appreciated... Code attached
