The original starting point for this library was the Adafruit_ILI9341
|
|
library in January 2015.
|
|
|
|
The licence for that library is MIT.
|
|
|
|
The first evolution of the library that led to TFT_eSPI is recorded here:

This is our library for the Adafruit ILI9341 Breakout and Shield
|
|
----> http://www.adafruit.com/products/1651
|
|
|
|
Check out the links above for our tutorials and wiring diagrams
|
|
These displays use SPI to communicate, 4 or 5 pins are required to
|
|
interface (RST is optional)

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

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

Contributions from other authors are recorded on GitHub:

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