it works on mipsel (WRTNode2P board MT7628) openwrt, thank you.

I hv modified send buffer to send at 32 bytes chunk instead of 128, it is MT7628 i2c bug

 

// send buffer to oled (show)
int oled_send_buffer(struct display_info *disp) {
        struct sized_array payload;
        uint8_t packet[129];
        int i;

        packet[0] = OLED_CTRL_BYTE_DATA_STREAM;
        payload.size = 33;
        payload.array = packet;

        for (int index = 0; index < 8; index++) {       
                for(i=0;i<4;i++)
                {
                        memcpy(packet+1, disp->buffer[index]+i*32, 32);
                        oled_send(disp, &payload);
                }
        }
        return 0;
}
 

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.
