I'm on it, tricky in parts but I'm on it

How many EEPROM locations are there on a PIC16F684?

As in:

EEPROM location 5

I think the 684 only has 256, if I remember correctly.

[LEDave]

Is that sequential 0-255?

Srub that, it's got to be I'm thinking.

See you tomorrow.

Hi mackrackit,

I'm busy working on the latest 'mission'. I'll stick at it and only ask a question when I'm stuck and have given it a good go to figure it out myself.

I do have one quick question though:

Can you add or subtract EEPROM memory location values (numbers written to an EEPROM address)? Or do you just give the stored WORD's a name and then subtract the two, something like: Parts_Run = Total - First_Parts_run (if this make sense).

While the value is in the EEPROM you can not go anything with it. You have to read the value into a variable, do something with it and write it back into the EEPROM.

I think that is what you are asking...

I think that is what you are asking...

Spot on.

I can almost hear mackrackit tapping his fingers on the table............!

Working really hard on this, I know what I want to do, I just need a breakthrough. At the moment I'm going around in circles.

I'll see what I can come up with tonight.


Tap, tap, tap...Stop it mackrackit...lol.
