Marius:
Have you tried the Intersil X9C102, X9C103, X9C104, X9C503 series. They are easy to drive (bit bash). I will give you some code if you need.
Hi Marius, do you have some code to share about the X9C102, X9C103, X9C104, X9C503 series ?
Could you give some idea how to get it wired up with the arduino too ?
Thanks!
