Features:
- very fast rendering even on ATMEGA Arduino
- no bitmap data is necessary - only rendering routines
- each number can have different width, height and segment thickness
- should work with any Arduino graphic library with user defined callbacks for drawLine() and fillRect()
- 3 styles of 7-segment font variation
- extra pseudo 3D look for color displays (style 2c)
- simple fast rectangular and outline styles
- each digit only cleans the necessary segments, so cleaning and refreshing the entire screen is not necessary (important for good performance on high definition LCD displays)
- examples for monochrome HX1230 and color ST7789 IPS
- each style has separate methods/functions to save program memory
- if necessary only 3-4 functions can be used separately (setSize,drawSeg,drawDigit,printNumber) without the library
- special look - multi layer rendering is possible: youtu.be/OPq9aBJP-pc
- new style #7 implemented, it can replace #1 and #2: youtu.be/Z_YCfJZn_bA
Uwe's application using OLED display: sciencetronics.com/greenphotons/?p=2211
0:00 - Available styles
0:29 - Demo on monochrome display
2:39 - Demo on color display
