Why Isn't My OLED Screen Updating with Pressure Readings on AVR128DA48?

        printk("Failed to bind to OLED I2C device\n");
        return;
    }

    const struct device *bmp280 = device_get_binding(DT_LABEL(DT_INST(0, bosch_bmp280)));
    
    while (1) {
        sensor_sample_fetch(bmp280);
        sensor_channel_get(bmp280, SENSOR_CHAN_PRESS, &pressure);

        char buffer[20];
        snprintf(buffer, sizeof(buffer), "Pressure: %d kPa", pressure.val1);
        cfb_print(oled_dev, buffer, 0, 0);

        cfb_framebuffer_finalize(oled_dev);
        k_sleep(K_SECONDS(2));
    }
}
