The utility came from Adafruit and while its not too capable it gets the job done Shown is a command prompt based utility where you feed some parameters in an old c:\> type prompt. If you must stick with the Adafruit driver, here's a video on how to create and use custom fonts from Windows TTF fonts. The utility is pretty easy to use, links to it provide in the vid Shown is how to use a utility that let's you convert fonts, adjust kerning, and create just a range 0-9 for example. If you can move to use the ILI9341_t3, here's a video that shows how to create and use custom fonts from Windows TTF fonts. My ILI9341_t3n library has examples, which include both types of fonts. Now depending on which Graphic library you end up using, you need to then have your sketch include the include file for the font. There are also places mentioned up on forum on tools and the like to create the fonts.Īdafruit GFX library also includes a set of fonts. Which sets it up as arduino new library format, which allows us to create an archive file from it, which than will cause Arduino linker to only include those fonts which are used. A few of us created version of that library: Warning however with this version of the font library it will include all of the fonts into your project which use up space. You can copy them in to your project or you can put these into a proper library location and simply include the header file for the font. The table will have true placed (meaning light up) in the index that we wanna light up, we want the frame number 5 to be lighten up, we put true in the 5th index in the table pattern for 0.Sorry hopefully some one who has edited their own fonts will chime in and give some more help.Īlso most of my stuff playing with this has been done using our own Teensy oriented drivers, like ILI9341_t3 or more with my own ILI9341_t3nįor these drivers we also have a different Font format defined, and there are some github projects up with lots of fonts like up at: Technically if we wanted to show zero in the displayer, we would need these certain segments to be lighten up the pattern for one, go to the next index and make another table Local patterns = -this is just ther pattern for 0, if you wanted Technically each number (from 0 to 9) has a certain pattern, so you wanna have a table containing all the appropriate patterns, this would be lots of work so good luck.Of course you wanna be using surface UIsĮach UI would be named after a number, and that number would describe that UIs order so the order does matter, because we need it in the scripting part Make a UI for each number, made up of 7 minor frames, and tweak them until they form a number.These are called 7-segment displayers, making them is pretty easy:
