Numeric display with ST7789 and Arduino - RREFont vs PropFont cbm80amiga 2020-02-15 | Quick numeric display tutorial- for nice digits I used 13x20 pixel font with 2x scaling in Y axis (so 13x40 pixels are rendered, even 16x40 with spacing)- regular bitmap fonts are very slow to render pixel by pixel (350ms in this example)- however, what "slow" really means can be checked by trying other ST7789 libraries :)- addeed special OPTIMIZE_BIG_FONTS mode which speeds up rendering of big bitmap fonts about 25%- RRE fonts encoded in vertical mode give the best results (about 100ms)- regular RRE fonts (rendered using rectangles) are the fastest and use less memory but flickering can be visible due to every character full background clearing before rendering- all static data should be drawn only once for the best performance- even on slow Arduino and high resolution ST7789 final results with RRE fonts are pretty promising, achieved 10 fps refresh rate for 5 big numeric fields using nice digitsThe code on my GitHub:github.com/cbm80amiga/Arduino_ST7789_Fast/tree/master/examples/ST7789_Numeric_displayIf you find it useful and you want to buy me a coffee or a beer:paypal.me/cbm80amiga
