// Set the font to Font 6x14 lcd_set_font(Font6x14);
(Note: This represents a typical structural format. Exact bitmap data varies by creator.)
The 14-pixel height allows for better character definition compared to 8-pixel tall fonts, making it less likely to cause eye strain.
Approximately 1.3 KB to 2 KB for a standard 95-character printable ASCII set, making it highly compatible with memory-constrained chips like the Arduino Uno (ATmega328P). Typical Applications and Hardware Compatibility Font 6x14.h Library Download
(column-by-column) bit mapping. If the text looks "scrambled," you likely need to flip the generation mode in your tool. Line Spacing : Since the font is 14 pixels high, set your cursor's increment to at least 15 or 16 to avoid overlapping lines.
: A fast rendering library for Arduino that uses lines/rectangles instead of full bitmaps to save flash space. It supports multiple architectures and often includes various fixed-size fonts. Arduino Forum How to Generate Your Own "Font 6x14.h"
If you need a specific style or missing characters, you can generate a custom file using these popular tools: LCD Image Converter : Converts any Windows/TTF font into C-header code. : Set the image size to 6x14 and export as a "C array." DotFactory // Set the font to Font 6x14 lcd_set_font(Font6x14);
Inside the header file, the data is represented as a multidimensional array. A snippet for an uppercase letter 'A' might look like this:
: A web-based tool where you choose a font family and size (like 14pt) and it outputs the C header array code. GLCD Font Creator
14 pixels. This fits efficiently into standard page-oriented display architectures (like the SSD1306 OLED, which processes data in 8-pixel-high pages). : A fast rendering library for Arduino that
void setup() if(!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) for(;;);
Bitmap fonts like this are a staple of embedded systems programming. They are represented as an array of pixel data, which is highly efficient for memory-constrained devices like an (which has only 2KB of SRAM). The .h file format is a standard for these fonts because it can be directly #include d into a C or C++ project. As one developer notes, all included fonts are in a bitmap format, specifically designed to work within the tight limitations of a small microcontroller, where total memory for font data and sketch code is a finite resource.
A typical font6x14.h file looks like this in C syntax:
