Reading EEPROM from a beginner

[Ron]

Hello,

I was wondering if someone could tell me

How long does it take to read 9 non-consecutive EEPROM addresses and pass this information into variables.


How long does it take to pass data from 9 variables and write 9 non-consecutive EEPROM addresses.

Base PIC controller would be either

16F886 4Mhz or 20MHz

Is thier other factors I have not considered?

Thanks

Ron

The easiest way to achieve this is to do the following.

Start the hardware timer TMR1 running.
Perform the read or write operations.
Collect the value in the timer register.

One thing to look out for is to make sure that the timer is not rolling over. ie going from its max value back to 0. This could be done by setting an interrupt to occur if the timer rolls over which prints a warning on the LCD etc.
