I had tried the code on my MT7688. But it gave me a surprise!!! The sh1106 could not be displayed normal,but the ssd1306 could be fine. But in the oled.h from the attachement, "#define OLED_SET_PAGE_ADDRESS 0xB0" is there ,and i dont know what happen ,it seems that the "#define OLED_SET_PAGE_ADDRESS 0xB0" did not be useful.
