16.h Library — Arial Black

Because it is a bitmap font, there is no sub-pixel rendering or anti-aliasing. The curves are rendered as best as possible within 16 pixels.

If you have ever dived into the world of low-level graphics programming—particularly for embedded systems, vintage operating systems, or DIY microcontroller projects with displays—you may have stumbled across a file named something like arial_black_16.h . The specific keyword phrase refers to a C/C++ header file that contains a bitmap representation of the Arial Black typeface at a 16-point size .

display.setFont(&arial_black_16); display.setCursor(x, y); display.print("Hello, World!"); arial black 16.h library

Additionally, a developer on an Arduino forum once experienced that on his ILI9341 display while other sizes (14px, 15px, 17px, 18px) worked perfectly. The problem was traced to a bug in the ILI9341_due.cpp library's bit management routine ( numRemainingBits ) when handling a height of 16. The bug was fixed by correcting the modulo calculation: const uint8_t numRemainingBits = charHeight % 8 == 0 ? 8 : charHeight % 8; .

: 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. Because it is a bitmap font, there is

Each character has a unique width, generally around 9 to 10 pixels, stored in a separate array within the header.

For instance, in a real application, the font structure might resemble:
