Looks like the class is not loaded. Did you import it in the libs folder of Arduino IDE ?

thommaughan commented 4 years ago

I have the library in the directory with all my other libraries. I did not use the arduino IDE to import it though. I have other libraries in the same folder that are copied in and all seems well.

I have been making progress on adding support for the 128Kx8 Fujitsu devices by hacking the Adafruit FRAM library (also copied). I'm a C programmer, and I'm a bit weak on C++ but I suspect something with the object instantiation / constructor call

//Creating object for FRAM chip FRAM_MB85RC_I2C mymemory();

vs the Adafruit way:

Adafruit_FRAM_I2C fram = Adafruit_FRAM_I2C();

Can you remove the brackets at the object creation ?

FRAM_MB85RC_I2C mymemory;

This is the way the example had been modified a few days ago.

Another way is using the constructor providing the chip address and the use write protect

FRAM_MB85RC_I2C mymemory(address, false);

Let me know

I'll give it a try when I get a time, thanks for the help
