A command-line utility bundled inside the popular Adafruit GFX Library environment. It interfaces with GNU free type files to compress specific sizing variants directly into layout headers.
Once the libraries are installed, you can begin writing your sketch. To use the Arial Black font, your code must include the necessary headers at the top of the file. arial black 16.h library
| Scenario | Better Alternative | |----------|--------------------| | Needing many font sizes | Use a vector font renderer (e.g., stb_truetype) | | Supporting Unicode (Chinese, Emoji) | Use a full GUI library (LVGL, u8g2) | | Anti-aliased text | Store 4-bit or 8-bit glyphs, but memory increases 4–8x | | High-performance scrolling | Use a framebuffer and blit pre-rendered text lines |
#include #include #include #include "Arial_black_16.h" // Include the font file // Setup DMD #define DISPLAYS_ACROSS 1 #define DISPLAYS_DOWN 1 DMD dmd(DISPLAYS_ACROSS, DISPLAYS_DOWN); void setup() dmd.selectFont(Arial_Black_16); // Select the font dmd.begin(); void loop() dmd.drawString(1, 1, "DATA", 4, GRAPHICS_NORMAL); delay(1000); Use code with caution. 4. Common Applications The Arial_black_16.h library is popular in:
DMD or P10 32x16 - Blue Tooth - Goto, Libraries and other Stuff. Compatible with libraries like ILI9341_t3
Ideal for digital clocks, temperature displays, and speedometers.
: This indicates that your main sketch cannot find the header file. Make sure Arial_Black_16.h is saved in the exact same directory folder as your primary .ino file, or placed inside your root Arduino libraries/ directory.
For hobbyists and makers, arial black 16.h is an excellent and convenient choice. It provides a clean, bold, highly legible font that is well-suited for a wide range of display projects. Its main strengths are its simplicity and that it works "out of the box" with the most common Arduino DMD libraries. h at master · freetronics/FTOLED · GitHub
Arial Black (known for its heavy weight and high visibility).
If you need more than ASCII, you can modify the library to support a sparse mapping of Unicode code points to bitmap data:
// Helper: pointer to data for a given character const uint8_t* get_char_data(char c) idx >= 96) idx = 0; // fallback to space return arial_black_16_data[idx];
// Font data for Arial Black 16px const unsigned char arial_black_16ptBitmaps[] PROGMEM = 0x00, 0x00, 0x00, // Character data represented in Hex 0x7C, 0xFE, 0xC6, // Each row or column of pixels // ... remaining character bitmaps ; const GFXfont arial_black_16pt PROGMEM = (uint8_t *)arial_black_16ptBitmaps, (GFXglyph *)arial_black_16ptGlyphs, 0x20, 0x7E, 16 // ASCII range and font height ; Use code with caution.
Each character has a unique width, generally around 9 to 10 pixels, stored in a separate array within the header.
