Font 6x14.h Library Download May 2026

Contiki, the OS for low-power IoT, historically shipped with a c64-fonts.h or similar bitmap sets. Their classic fonts/6x14.h is available in their source tree.

#include "Font6x14.h"
// Initialize the display and font library
void setup() 
    font6x14_init();
// Render a string on the screen
void loop() 
    font6x14_render_string(10, 10, "Hello, World!");
    // Update the display...
int main() 
    setup();
    loop();
    return 0;

The easiest way is to let a library do the drawing for you.

Method A: Using U8g2 (Supports 6x14 natively)

#include <U8g2lib.h>
#include <Wire.h>
// Initialize for SSD1306 OLED
U8G2_SSD1306_128X64_NONAME_1_SW_I2C u8g2(U8G2_R0, /* clock=/ SCL, / data=/ SDA, / reset=*/ U8X8_PIN_NONE); Font 6x14.h Library Download
void setup() 
u8g2.begin();
u8g2.setFont(u8g2_font_6x14_t); // <-- The 6x14 font built-in
u8g2.setFontDirection(0);

void loop() 
u8g2.firstPage();
do 
u8g2.drawStr(0, 14, "Hello, 6x14!");
u8g2.drawStr(0, 28, "Second line");
 while ( u8g2.nextPage() );

Method B: Manual Integration (For custom display drivers) If you are writing your own LCD driver (e.g., for an ST7920 or ILI9341), you will write a function like this:

#include "font6x14.h" // Your downloaded file
void draw_char(int x, int y, char c, unsigned int color) 
int i, j;
unsigned char mask;
// Calculate the index in the array (assuming ASCII starts at 32)
const unsigned char *ch = &font6x14[(c - 32) * 14];
for(i = 0; i < 14; i++)  // 14 rows
    mask = ch[i];
    for(j = 0; j < 6; j++)  // 6 columns
        if(mask & (1 << (7 - j))) 
            set_pixel(x + j, y + i, color); // Your low-level pixel function

#ifndef FONT_6X14_H
#define FONT_6X14_H
#include <stdint.h>
// Font Metrics
#define FONT_6X14_WIDTH  6
#define FONT_6X14_HEIGHT 14
#define FONT_6X14_FIRST_CHAR 32  // Space
#define FONT_6X14_LAST_CHAR   126 // '~'
// Total bytes = (Height + 7) / 8 * Width
// For 14px height: (14 + 7) / 8 = 2 bytes per column
// 2 bytes * 6 columns = 12 bytes per char
#define FONT_6X14_BYTES_PER_CHAR 12
// Storage array (stored in Flash for AVR/STM32)
extern const uint8_t Font6x14[];
#endif // FONT_6X14_H

// Assumptions: column-major storage, bytes_per_glyph known, read_byte abstracts pgm_read_byte if needed
void drawChar(int x, int y, char c) 
  int index = c - FIRST_CHAR;
  const uint8_t *glyph = font_data + index * BYTES_PER_GLYPH;
  for (int col = 0; col < FONT_WIDTH; col++) 
    uint16_t colBits = read_glyph_column(glyph, col); // up to 14 bits
    for (int row = 0; row < FONT_HEIGHT; row++) 
      if (colBits & (1 << row)) setPixel(x + col, y + row);

Because this is a developer-centric file, you will rarely find a standalone website hosting just this file. Instead, it is bundled inside larger, reputable libraries. Do not download random .h files from untrusted file repositories; always get them from official source control or bundled libraries.

Here are the safest and most reliable sources for Font 6x14.h: Contiki, the OS for low-power IoT, historically shipped

The raw data for 6x14 is efficient, but if only numbers and uppercase letters are needed, the array size can be reduced by defining a custom FIRST_CHAR and LAST_CHAR index, effectively "cropping" the font table.

The 6x14.h library represents a pragmatic choice for embedded graphics. It strikes a distinct balance between the low memory usage of 5x7 fonts and the superior readability of larger fonts. By utilizing vertical byte mapping, it remains compatible with standard display controller logic while offering enhanced vertical resolution for modern applications.
