On Interrupt Goto (for pic18f252 ) Help

[jetpr]

who i disable all interrupt by writing to INTCON a the begining
and re-enable them at the end?

[mister_e]

disable al interrupts:
INTCON=0

reenable... use the one you declare at the begining:INTCON = $a0 ' Enable TMR0 interrupts

also don't forget to add Enable after Resume

Here's what you need. i'm using the internal USART @2400 baud.

Forget about the INTCON stuff i said before..

P.S. By writing to internal EEPROM as often as you do, you'll burn it soon, You should consider the use of external EEPROM like FRAM OR by saving your data only when the Voltage goes bellow a certain threshold. For cheapness i'll use the last option.
