Hi Vijay,

Hi Yuhao,

That Example code is write only.

How to Read that?

at what memory location the data is stored?

Thanks & Regards,

Vijay

Hi Vijay, 

In the example code, data is stored in FRAM_write[], which is defined by #pragma PERSISTENT.

• #pragma PERSISTENT(FRAM_write)

You can read or write FRAM_write[] just like a normal variable.

You can also find the memory location in .cmd file.

Thanks,

Yuhao

Hi Yuhao,

When the code is first executed, the array value is properly stored, but the array always has a value of 0 once the power is switched off and back on.

Thanks,

Vijay

Hi Vijay,

I notice that there is a define to set the FRAM_write[] to be zero at the beginning. 

Maybe you can modify it as

• unsigned long FRAM_write[WRITE_SIZE];

Thanks,

Yuhao
