I received an interesting display for test (OLED technology, 128x128 resolutios, SSD1327 driver) for made to work with ESP32 development board.
Default, connexion is for SPI, but you can change to i2c connexion, see in schematic from here.
I search info and after few tests, I used with good results u8g2 library and my config is
U8G2_SSD1327_MIDAS_128X128_F_4W_SW_SPI u8g2(U8G2_R0, /* clock=*/ 13, /* data=*/ 12, /* cs=*/ 14, /* dc=*/ 27, /* reset=*/ 26);
You can see 1.5” OLED display with ESP32 movie
