Arduino uno с библиотекой microled; рисовать в форме

Прошу прощения за беспокойство, но мне снова нужна помощь с моим кодом Arduino. Я все еще учусь, поэтому делаю ошибки.

Я пытаюсь рисовать фигуры на экране i2c с помощью библиотеки Microled. Мой код не компилируется, ошибка Неожиданное объявление перед { . Это одна проблема. Я также хотел бы нарисовать прямоугольник без краев, как пустой, так и заполненный, но я изо всех сил пытаюсь объявить его, должен ли я объявить 4 строки или, возможно, отобразить растровое изображение.

В любом случае мой код здесь

#include <Arduino.h>
#include <Wire.h>
#include <MicroLCD.h>

LCD_SH1106 lcd; /* for SH1106 OLED module */
//ЖК-дисплей_SSD1306; /* для OLED-модуля SSD1306 */
