Hi,

ever since i replaced my memory ic (FRAM) from MR44V100A to FM24V10, i can not get my system work properly. There is no communication between PIC Microcontroller and FRAM. 

Can you please advise me in this regards? if needed I can share code as well which is written in mikroc IDE.

Thanks in advance,

Nuaman Saghir

Hi,

If you are not able to communicate with the device we may need to check a few things. Can you share

1) The schematics of the FRAM portion.

2) The wave forms for read and write. If there is nothing on the scope there may be an issue with the master.

3) The resistor values on the I2C lines.

Thanks,

Pradipta.
