How to use an SSD1603 (oled 0.96'') with Attiny85

hello all!
as mentioned in title, i'm trying use ssd1603, mini oled 0.96'' attiny85 programmed arduino nano spi.
i know have use library, , searcing on google found out:
- ssd1306_minimal
- tinywirem
- usi_twi_master

so question is: type of "command" (or "function"?) contains these libraries?
in other words, esample, print letter "a" in middle of display, string have write program?

another question: know other libraries might useful project?

thanks, guatta

you use u8x8 api of u8g2 library.
use u8x8_ssd1306_128x64_noname_sw_i2c constructor display. no other libs required.
