Arial Black 16.h Library -

Move arial_black_16.h into your Arduino sketch folder (or the src folder of your PlatformIO project).

Introduction: The Ghost in the Machine In the age of terabyte storage and gigabit fonts, it is easy to forget the constraints of early computing. For modern developers, importing a font is as simple as dropping a .ttf file into a folder. However, for embedded systems engineers, retro game developers, and firmware wizards, memory is measured in kilobytes, not gigabytes. arial black 16.h library

void setup() { u8g2.begin(); u8g2.setFont(arial_black_16); // Note: The variable name inside your .h file } Move arial_black_16

#include <Wire.h> #include <Adafruit_SSD1306.h> #include "arial_black_16.h" // Your custom library If you are using Adafruit_GFX, you need a custom print class. However, if you use U8g2 , the process is much easier because U8g2 accepts these headers natively: for embedded systems engineers
