ABOUT SSD1306
No,  the mega328 has 2048 bytes of SRAM.   The array size is fine. There are some minor errors in the code.   The initialisation sequence "looks" ok,...

In #31 you explain that you have XMINI boards and also ATmega328, ATtiny85 with USBASP.   I conclude that you are not an impecunious 12 year old.    You have...

The digispark contains USB software and bootloader. If you attempt to use AS7 the USB/boot code will be erased.   Life is simpler if you use a ATmega328P.   You...

I2C Stopping Project Functionality - ATmega328P
I suspect that you are using the 7-bit address.  Fleury expects an 8-bit address. Always use return values.   Never use i2c_start_wait().   It will just hang...
