      1 The original starting point for this library was the Adafruit_ILI9341
      2 library in January 2015.
      3 
      4 The licence for that library is MIT.
      5 
      6 The first evolution of the library that led to TFT_eSPI is recorded here:

     29 Selected functions from the Adafruit_GFX library (as it was in 2015) have
     30 been imported into the TFT_eSPI.cpp file and modified to improve
     31 performance, add features and make them compatible with the ESP8266 and
     32 ESP32.
     33 
     34 The fonts from the Adafruit_GFX and Button functions were added later.
     35 The fonts can be found with the license.txt file in the "Fonts\GFXFF"
     36 folder.
     37 
     38 The Adafruit_GFX functions are covered by the BSD licence.

     71 Due to the evolution of the TFT_eSPI library the original code may no longer
     72 be recognisable, however in most cases the function names can be used as a
     73 reference point since the aim is to retain a level of compatibility with
     74 the popular Adafruit_GFX graphics functions.

     79 The major addition to the original library was the addition of fast
     80 rendering proportional fonts of different sizes as documented here:
     81 
     82 https://www.instructables.com/id/Arduino-TFT-display-and-font-library/
     83 
     84 The larger fonts are "Run Length Encoded (RLE)", this was done to
     85 reduce the font memory footprint for AVR processors that have limited
     86 FLASH, with the added benefit of a significant improvement in rendering
     87 speed.
     88 
     89 In 2016 the library evolved significantly to support the ESP8266 and then
     90 the ESP32. In 2017 new Touch Screen functions were added and a new Sprite
     91 class called TFT_eSprite to permit "flicker free" screen updates of complex
     92 graphics.
     93 
     94 In 2018 anti-aliased fonts were added along with a Processing font conversion
     95 sketch.
     96 
     97 In 2019 the library was adapted to be able to use it with any 32 bit Arduino
     98 compatible processor. It will run on 8 bit and 16 bit processors but will be
     99 slow due to extensive use of 32 bit variables.
    100 
    101 Many of the example sketches are original work that contain code created
    102 for my own projects. For all the original code the FreeBSD licence applies
    103 and is compatible with the GNU GPL.
