Arial Black 16.h Library Info

When microcontrollers drive hardware like a P10 dot-matrix LED panel or an SPI-driven OLED screen, they cannot process standard TrueType ( .ttf ) or OpenType ( .otf ) font files directly. These systems lack the processing power and operating systems needed to rasterize vector vector-curves on the fly.
