This is a specialty pixel font for 8x8 LED dot matrix displays. Its raison d'etre is to display the time (in 24h HH:MM format) and/or the temperature (with a precision of up to 1 decimal) in an esthetic and optimal manner on four 8x8 displays. Adding two more matrix displays will allow seconds and more decimals to be shown.
The font is proportional, but lacks kerning. The glyphs have one-pixel margins left and right to implement kerning, as it were, with the decimal point. Character spacing (or rather, digit spacing) is therefore 2 pixels.
In order to use the font with ESPHome without rendering issues, I opened the TrueType file with FontForge, added an 8-pixel bitmap (Elements>Bitmap Strikes Available...>Pixel Sizes: 8) and generated the font (File>Generate Fonts...) under a new file name, simasuu_8.ttf.
This is a cloneThis font is designed to look as if each character was on a digital clock. However, I will make it clear that this font is NOT a 7-segment display font. It is modeled after the STYLE of a seven-segment display, but I tried to make each glyph distinct, which would not be possible with a 7-segment font. (for example H&K, A&R, I&l&1 and B&8&θ)
I still (sometimes) stuck to the seven-segment format for most characters (like digits 1-9) but the font still truly isn't a 7-segment font.
I also TRIED to make it a monospace font (you can see that the Ms and Ws are squished) but for all of that small punctuation, it just wasn't too feasible.
I will hopefully add 10 glyphs per day (random glyphs) until all available fontstruct glyphs are complete, but this will not always happen.
Feel free to comment, make suggestions, download, and build upon! Have a great day!
