That's most likely your problem right there. Go with external crystal, resonator, oscillator, something...Originally Posted by docaberle
But since you said you're having overrun errors, look at the 'F688 datasheet in the OSCTUN section and dial down your internal clock a couple of notches and see what happens.
Problem is, this will only work at that particular battery voltage, that temperature, that day of the week, when the moon is in that particular phase, etc.etc.etc...
Just save the trouble and go with an external clock source...
Could it be something else causing the problem?
Sure...trying to SEROUT while at the same time receiving serial data in the hardware...bad idea... I'd also be willing to bet if you took all of those SEROUT statement and made it so that each SEROUT statement only did one, two, maybe three characters at a time, you're overrun errors might go away, since it'll give the program/hardware a chance to interrupt and empty out the incoming hardware serial buffer.
