You switched accounts on another tab or window. This file defines two structures: typedef struct { // Data stored for FONT AS A WHOLE: uint8_t *bitmap; // Glyph bitmaps, concatenated GFXglyph *glyph; // Glyph array uint8_t first, last; // ASCII extents uint8_t The GIF decoder builds on Adafruit Arcada which supports the SAMD51 chipset and color GFX displays. h > This creates a global object, display (it’s global — usable anywhere in the sketch — because it’s declared outside any function), of type DVIGFX16, which is a 16-bit color framebuffer (a section of memory dedicated for graphical display). So you probably say setFont(SystemFont5x7) I suggest that you look through the ILI9341_due examples. CircuitPython USB Workflow Code Editor Quick Start. You get 240x320 pixels with individual 16-bit color pixel control. We only need two things. h (and all that these codes call) The corresponding Adafruit library routines have also been tried.
