![]() The first character is placed at position x and y. See also: setDrawColor, drawFrame, drawBox.For a monochrome display, the color index 0 will clear a pixel and the color index 1 will set a pixel. This procedure uses the current color index to draw the box. Behavior is undefined if w or h is smaller than 2*(r+1). Parts of the box can be outside of the display boundaries. Description: Draw a box/frame with round edges, starting at x/y position (upper left edge).The "snowman" is also part of the u8g2 font u8g2_font_unifont_t_symbols (see below). Example: The "snowman" glyph is part of the unicode weather symbols and.Note: This drawing function depends on the current font mode and drawing color.encoding: Unicode value of the character.x, y: Position of the character on the display.The X2 variant of this function will double the size of the glyph but will ignore the font direction setting. The glyph can be drawn only, if the encoding exists in the active font. U8g2 supports the lower 16 bit of the unicode character range (plane 0/Basic Multilingual Plane): The encoding can be any value from 0 to 65535. The character is placed at the specified pixel posion x and y. Note: Draw color 2 (XOR Mode) is not supported.opt: Selects some or all sections of the disc.rad: Defines the size of the circle: Radus = rad.x0, y0: Position of the center of the disc.This procedure will use the current color ( setDrawColor) These values can be combined with the | operator. U8G2_DRAW_UPPER_LEFT, U8G2_DRAW_LOWER_LEFT, Possible values for opt are: U8G2_DRAW_UPPER_RIGHT, ![]() Description: Draw a filled circle with radus rad at position (x0, y0).ĭepending on opt, it is possible to draw only some sections of the disc.Example 1: Left adjusted text with 2 pixel space ( padding_h=2 and padding_v=2) around the text and a 2 pixel border ( BW2).Note: Font mode is set to 1 by this function (see setFontMode). ![]() text: UTF8 encoded string which will be drawn on the display.padding_v: Extra space above and below the text.padding_h: Extra space before and after the text.If 0 (or lower than the text width), then the text width is used for the frame. Multiple flags can be used with the "or" operator. If U8G2_BTN_HCENTER is used, then this is the center position of the text. x, y: Position of the first character on the display.u8g2 : Pointer to the u8g2 structure (C interface only).This is similar to drawUTF8,įrame around the text, 1 pixel border widthįrame around the text, 2 pixel border widthįrame around the text, 3 pixel border widthĬenter the text inside the frame and change the reference position to the center of the textĭraw second 1-pixel frame around the button Description: Draw a frame / box around a provided text.Void u8g2_DrawButtonUTF8(u8g2_t *u8g2, u8g2_uint_t x, u8g2_uint_t y, u8g2_uint_t flags, u8g2_uint_t width, u8g2_uint_t padding_h, u8g2_uint_t padding_v, const char *text) See also: initDisplay setPowerSave clearDisplay U8X8::begin.Select, next and prev pins are also required for the user interface procedures (for example Use getMenuEvent to check for any key press event. The switch has to connect the GPIO pin with GND (low active button). ![]() Use U8X8_PIN_NONE if there is no switch connected to the pin. The Arduino pin numberĬan be assigned here. This function will reset, configure, clear and disable power save mode of See the setup guide for the selection of a suitable U8g2 constructor.
