If your screen dimensions are different, you can still see the size relative to the FreeFonts of a given size.) Your own fonts (This only works if your screen is 320x240 pixels. Same size as they are on the virtual device on the screen above. And then there's the different fonts displaying at radically different sizes due to various metricsįor details.) But I don't have to care about that: when I make gfx fonts and include them on my device, they are the of Adafruit 2.8" TFTīut since everyone keeps the setting, a certain font at 20 points is going to take up the same number of pixels on a In the Adafruit software it says: #define DPI 141 // Approximate res. Or that's what it's supposed to mean, but pretty much everyone that uses the Adafruit software keeps the setting of 141 pixels per inch. The size thingįont sizes are given in points, where a point is 1/72 of an inch, describing the actual size on a display.
Simply select a FreeFont or upload any TrueType font, select a size, download the include file and you're ready to use the font in your project. No need to compile tools, no more guessing how big a font will be. It involves compiling tools and a trial-and-error process for figuring out how big the font will turn out on your display.īut now you can skip all that and convert the fonts your Arduino project needs with ease.
Some fonts usually are included with the driver, and then there's a complicated procedure for adding your own fonts. And the Adafruit GFX display driver is used by many of them to display variable-width fonts. Many Arduino projects and ready-built devices come with a display.
