pic16f877a and writing data to eeprom

[rahul95]

hi

i m new to pic programming. i m doing my project using pic16877a,keypad and lcd , i want to make pic to update time continuously(timer0 interrupt) , so furthermore i m thinking to write data to eeprom.(i have read that there should be minimum 20ms delay between successive use of routines EEPROM_Write and EEPROM_Read)

so if i add a delay to code, will it effect to time updating..

please help

thanks

nah, no worrieS!! its called an interrupt for a reason!

Time is updated through Timer0 interrupt. So, nothing in the code (besides altering Timer0 and interrupt settings) can affect time update. So, the delay between EEPROM write and read functions will not affect time update.

Hope this helps.
