16f84a + 24lc16b Eeprom

[exelanoz]

Well after much experimentation (putting a ZIF socket thru its paces)
**my programmer and hobby testbed are two different things. I endavour to put a programmer connection on my testbed eventually, when my little spare time allows**
i tried a 24lc256, and yes it does use a word address. Works well, or at least it appears that way.

But leaving the code 'as is' leaves the last character of line 1 in the variable E_Byteout, and it displays this last character in the second line address range.

So...I put together the whole thing in one line and write it (address = 0 to 18), then next read out the text on two seperate lines.(address = 0 to 10 and 11 to 18)

My 2 questions are:
Why can't I put 2x "Lookup" one after the other like I have in the example.
Why won't the EEPROM record anything if I use the FOR and NEXT command to insert the address word say from 18 to 36?

Many thanks

**Oh one last thing. Sentence in the first section needs clarifying. My aim is not to write variable bytes into the EEPROM...instead i should be going along the lines of 'wanting to write character strings into it and then retrieving them from alternate locations' :-)

Hehe Super Duper! It's Working!

Finally i've got it all worked out.
As they say "more than one way to skin a cat", - sorry, I mean no offence to any animal lovers. (I love my beautiful pet fishes)

I had problem writing to different memory locations on a 24LC16.

Like write:

"Fish" to 0 to 3 (locations)

after that put

"plant" to 20 to 25 (locations)

All good now. It was a simple fix.

I would love to see some replies to any future posts...over 50 views and no reponse? What little I know is self taught, so expect to see some ridiculous code from me:-) and don't laugh.
