Fram Support #29

Closed Jim-bee closed 2 years ago

Jim-bee commented 2 years ago

It is possible to add support for Fujitsu's MB85RC fram series (MB85RC128A for example).

Thanks,

Are you asking if I can add it to the list of devices recognized by the I2C_Detect function? After looking at the data sheet, I would say "no". The reason being that it doesn't have a "WHO_AM_I" register nor is there a non-destructive sequence to know if it's that FRAM chip. I would have to write data and read it back to know if it's that chip. That breaks my "non-destructive" test rule.
