Build Error on Example

Board: AdaFruit Feather M0
Example: FRAM_I2C_simple_write_read

FRAM_I2C_simple_write_read:44:11: error: request for member 'begin' in 'mymemory', which is of non-class type 'FRAM_MB85RC_I2C()'

mymemory.begin();

       ^

FRAM_I2C_simple_write_read:52:21: error: request for member 'writeByte' in 'mymemory', which is of non-class type 'FRAM_MB85RC_I2C()'

resultw = mymemory.writeByte(writeaddress, writevalue);

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

[thommaughan]

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.

[sosandroid]

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

FRAM_MB85RC_I2C mymemory(address, false);

Let me know

[thommaughan]

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