I have tried everything my expertise in programming, which is limited, allows to change the SDA and SCL to different pins but have had no luck. Any help on this front would be appreciated.

That’s what I thought, but it doesn’t show up on the Arduino IDE. And when I try to run the large array code I run out of memory. Can you advise how to use the SPI Ram?

Is it possible to get more dynamic memory? I need bout 0.75-1 Meg for the arrays.

I cannot seem to write to the LCD display and read values from three devices on the I 2C bus at the same time. Individually the devices work fine and values can be displayed on the serial terminal. Also, the graphics example program works fine. Combining the two does not work. I can create an instan...
