| createSprite() | The createSprite() function is used in the LovyanGFX library to create graphic sprites. Before drawing patterns, the screen size needs to be configured. | LGFX_Sprite createSprite(int16_t w, int16_t h); | w: the width of the sprite. h: the height of the sprite. Return value: an object of type LGFX_Sprite, representing the created graphic sprite. |
| fillRect() | The fillRect() function is used in the LovyanGFX library to draw rectangles. | void fillRect(int32_t x, int32_t y, int32_t w, int32_t h, uint32_t color); | x, y: the coordinates of the upper-left corner of the rectangle. w, h: the width and height of the rectangle. color: the fill color. It can be an RGB888 format color value or an RGB565 format color value. |
| drawLine() | The drawLine() function is used in the LovyanGFX library to draw straight lines. | void drawLine(int32_t x0, int32_t y0, int32_t x1, int32_t y1, uint32_t color); | x0, y0: the starting coordinates of the line. x1, y1: the ending coordinates of the line. color: the color of the line. It can be an RGB888 format color value or an RGB565 format color value. |
| drawCircle() | The drawCircle() function is used in the LovyanGFX library to draw circles. | void drawCircle(int32_t x, int32_t y, int32_t r, uint32_t color); | x, y: the coordinates of the center of the circle. r: the radius of the circle. color: the color of the circle. It can be an RGB888 format color value or an RGB565 format color value. |
| loadFont() | The loadFont() function is used in the LovyanGFX library to load small fonts. | void loadFont(small); | small: the type of small font to be loaded. |
| setTextColor() | The setTextColor() function is used in the LovyanGFX library to set the text and background colors. | void setTextColor(uint32_t color1, uint32_t color2); | Color1: the color of the text. It can be an RGB888 format color value or an RGB565 format color value. Color2: the color of the background. It can be an RGB888 format color value or an RGB565 format color value. |
| drawString() | The drawString() function is used in the LovyanGFX library to draw strings. | void drawString(const char* str, int32_t x, int32_t y); | str: the string to be drawn. x, y: the coordinates of the lower-left corner of the string. |
| pushSprite() | The pushSprite() function is used in the LovyanGFX library to draw graphic sprites on the screen. After drawing the pattern, this function needs to be called. | void pushSprite(int32_t x, int32_t y); | x: the horizontal coordinate of the sprite on the screen. y: the vertical coordinate of the sprite on the screen. |
