Hi,
I have strange issue with a 16F628A. Its running a LCD display with a clock on it, and for some reason after a few days (time varies) it does a reset. I know this, because when I change the time, I store it in EEPROM, so after a reset, it reads the stored time..
Anyone an idea why this could be.. I've tried running it with MPASM debuger for over a day or two, but i got no errors..
Its powered by a small (400mA transformer) dc circuit with a 2200uf capicitor before a 7805..
I also tried another PIC, but same problem. Could it be caused by powerdips in the 230v? (would surprise me, because the capicitor is quite large..)
