The Adafruit GFX library has a number of custom fonts ranging in size from 9-24 points. There is a mono space font similar to Courier, a Sans Serif similar to Arial or Helvetica, and a Serif font similar to Times. There are also bold, oblique, and bold oblique versions of each of these.
How to select system font with Adafruit_GFX library? tft.println (“my foonting turlingdromes.”); tft.println (“see if I don’t!”); The regular way to select the System font with an Adafruit_GFX library is setFont (NULL) It looks as if ILI9341_due library provides its own “equivalent” methods instead of inheriting the real Adafruit_GFX class.
How to convert fonts from TrueType to GFX on Arduino? truetype2gfx is as a web utility to convert fonts from TrueType to GFX, which is used the Adafruit GFX library for Arduino. Many Arduino projects and ready-built devices come with a display. And the Adafruit GFX display driver is used by many of them to display variable-width fonts.
What are the limitations of Adafruit font format? The primary limitation of the Adafruit font format is that the character code point is used as an index, so you end up with adding lots of rarely/never used characters to the set. This could be fixed by extending the Glyph struct to include the code point and then search for the code.
What are the GNU FreeFont files? The GNU FreeFont files are not included in the library repository but are easily downloaded. Or you can convert most any font you like. The name assigned to the font structure within this file is based on the input filename and font size, not the output.

What is Adafruit GFX library? Adafruit GFX Library. This is the core graphics library for all our displays, providing a common set of graphics primitives (points, lines, circles, etc.). It needs to be paired with a hardware-specific library for each display device we carry (to handle the lower-level functions).
How to convert fonts from TrueType to GFX on Arduino? truetype2gfx is as a web utility to convert fonts from TrueType to GFX, which is used the Adafruit GFX library for Arduino. Many Arduino projects and ready-built devices come with a display. And the Adafruit GFX display driver is used by many of them to display variable-width fonts.
What is truetype2gfx? truetype2gfx – converting fonts from TrueType to the Adafruit GFX library for Arduino « Adafruit Industries – Makers, hackers, artists, designers and engineers! truetype2gfx is as a web utility to convert fonts from TrueType to GFX, which is used the Adafruit GFX library for Arduino.
How to convert TTF fonts to Adafruit_GFX header format? ‘fontconvert’ folder contains a command-line tool for converting TTF fonts to Adafruit_GFX header format. You can also use this GFX Font Customiser tool ( web version here) to customize or correct the output from fontconvert, and create fonts with only a subset of characters to optimize size.
How to select system font with Adafruit_GFX library?
Is there a way to create fonts for the Adafruit GFX? Nope. Each character in the font (“glyph”) specifies the dimensions and offset of the character, and also the “advance” – how far to move the cursor after printing the character. @Majenko I’m surprised there isn’t an easy way to create fonts for the Adafruit GFX.
How to install Adafruit libraries on Arduino? In the Arduino Library Manager window, search for a display’s driver type (e.g. “SSD1325”) and the appropriate Adafruit library can be found in the results. Required companion libraries (“dependencies,” like Adafruit_GFX or Adafruit_BusIO) now get installed automatically.
How to convert fonts in Arduino? One possible solution you might already have: There’s a small utility called fontconvert that’s part of the Adafruit GFX library. The source code is installed by default together with the Adafruit GFX library in Arduino/libraries/Adafruit_GFX_Library/fontconvert You need Linux to compile it from the provided source code.
What libraries work with Adafruit_GFX? Some of the libraries that operate alongside Adafruit_GFX include: RGBmatrixPanel, for our 16×32 and 32×32 RGB LED matrix panels. Adafruit_TFTLCD, for our 2.8″ TFT LCD touchscreen breakout and TFT Touch Shield for Arduino. Adafruit_HX8340B, for our 2.2″ TFT Display with microSD. Adafruit_ST7735, for our 1.8″ TFT Display with microSD.
