libraries for Arduino and ESP32—to render a bold, 16-pixel high font on LED matrix panels like the P10. Core Functionality
The name "Arial Black 16" means the font is exactly . If your DMD panel is 32x16 pixels, this font is the maximum height your single panel can physically display. To use a larger font, you would need to either: arial black 16.h library
: Expanded fonts like 16px headers often have unique baseline offsets. Adjust your Y-axis cursor coordinates slightly lower than you would for standard 8px system fonts to avoid cutting off the top of your characters.
