To use the Arial Black 16.h library in an embedded project (such as an Arduino, ESP32, or STM32 platform paired with an SSD1306 OLED or ST7789 TFT display), follow these steps: Step 1: Include the Library For example, in a hypothetical GUI library's header
The Arial Black 16.h library offers several features that make it a popular choice among developers and designers. Some of its key features include:
void loop() dmd.clearScreen(true); // Clear the screen dmd.selectFont(Arial_Black_16); // Choose the large font dmd.drawString(0, 0, "HELLO", 5); // Draw "HELLO" at x=0, y=0 delay(2000); // Wait for 2 seconds
