Arduino Nano with ssd1315 oled

Other Hardware Displays

Thank you for reading.
I have an oled display that uses the 1315 chip: it is the HS96L03W2C03 from LSCS (JLCPCB). HS96L03W2C03 | HS | Price | In Stock | LCSC Electronics

Having a lot of trouble finding a library that works with this oled.
Does anyone know of a library for this?

I have used the U8g2 lib, however it used all memory on my Nano to function. After commenting out 90% of my code it did write to the OLED.

I am now trying the U8x8 API which seems like it's bases on the U8g2 lib but uses much less memory? EDIT: the u8x8 api writes directly to the oled, rather than using buffer RAM memory of the arduino.

EDIT: The u8x8 api worked. Hopefully this can save a lot of time and confusion.
NOTE: the constructor specifies sd1306, however this does work for the ssd1315 display driver chip.

This is the code that I added to my project.
