Datasheet

Software SPI is not as fast (maybe 1MHz max on an UNO), but you can switch pins around.

Begin

You can initialize the SPI interface and chip with begin()

fram.begin()

It will return true or false depending on whether a valid FRAM chip was found

Writing

Then to write a value, call

fram.writeEnable(true);

fram.write8(address, byte-value);

fram.writeEnable(false);

to write an 8-bit value to the address location

Later on of course you can also read with

fram.read8(address);

which returns a byte reading. For writing, you must enable writing before you send data to

the chip, its for safety! However you can write as much as you want between the

writeEnable calls

Block Protection

We dont cover how to protect subsections of the FRAM chip. It's covered a bit more inside

the Datasheet.

For advanced users, we have two functions to set/get the Status Register. IF you want to set

the status register dont forget that WP must be logical high!

uint8_t getStatusRegister();

setStatusRegister(uint8_t value);
