External eeprom library

[Neetee 0]

Hello all 

I am almost done with my project due to all  your help

Posting probably the last query 

I am trying to download library for external eeprom connected using i2c to my msp430f5529 launch pad.

The entire library is available on github 

As github recently updated the website i cannot download the new libraries. Can anyone help me out by providing some other sources for this library.

Library i am searching is 

External eeprom using i2c for msp430f5529 launch pad 

Thanks and regards

But will this work for 5529 launch lad ?

Hallo Neetee,

The routines/functions are very generic.

Maybe the I2C pins are different.
But that is no problem.

Just try it.
That's the fun of experimenting.That;s why I love this as a hobby.
If it is for money, pleas try it and you can pay me royalties.

Come on, go for it.

Greetings from a very sunny Netherlands.

Cool with it 

I will try for this and if required will make changes in it and i will post on this forum for others to use
