+
+Only raise issues for problems with the library and/or provided examples. Post questions, comments and useful tips etc in the "Discussions" section.
+
+To minimise effort to resolve issues the following should be provided as a minimum:
+1. A description of the problem and the conditions that cause it to occur
+2. IDE (e.g. Arduino or PlatformIO)
+3. TFT_eSPI library version (try the latest, the problem may have been resolved!) from the Manage Libraries... menu
+4. Board package version (e.g. 2.0.3) available from the Boards Manager... menu
+5. Procesor, e.g RP2040, ESP32 S3 etc
+6. TFT driver (e.g. ILI9341), a link to the vendors product web page is useful too.
+7. Interface type (SPI or parallel)
+
+Plus further information as appropriate to the problem:
+1. TFT to processor connections used
+2. A zip file containing your setup file (just drag and drop in message window - do not paste in long files!)
+3. A zip file  containing a simple and complete example sketch that demonstrates the problem but needs no special hardware sensors or libraries.
+4. Screen shot pictures showing the problem  (just drag and drop in message window)
+
+The idea is to provide sufficient information so I can setup the exact same (or sufficiently similar) scenario to investigate and resolve the issue without having a tedious ping-pong of Q&A.
+
+DO NOT paste code directly into the issue. To correctly format code put three ticks ( ` character on key next to "1" key) at the start and end of short pasted code segments to avoid format/markup anomolies. [See here:](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#quoting-code)
+
+Example output:
+
+```
+  Serial.begin(115200);
+  tft.init();
+```

 A ["Discussions"](https://github.com/Bodmer/TFT_eSPI/discussions) facility has been added for Q&A etc. Use the ["Issues"](https://github.com/Bodmer/TFT_eSPI/issues) tab only for problems with the library. Thanks!
 # News
-1. New anti-aliased graphics functions to draw lines, wedge shaped lines, circles and rounded rectangles. [Examples are included](https://github.com/Bodmer/TFT_eSPI/tree/master/examples/Smooth%20Graphics). Examples have also been added to [display PNG compressed images](https://github.com/Bodmer/TFT_eSPI/tree/master/examples/PNG%20Images) (note: requires ~40kbytes RAM).
+1. New functions have been added to draw smooth (antialiased) arcs, circles, and rounded rectangle outlines. New sketches are provided in the "Smooth Graphics" examples folder. Arcs can be drawn with or without anti-aliasing (which will then render faster). The arc ends can be straight or rounded. The arc drawing algorithm uses an optimised fixed point sqrt() function to improve performance on processors that do not have a hardware Floating Point Unit (e.g. RP2040). Here are two demo images, on the left smooth (anti-aliased) arcs with rounded ends, the image to the right is the same resolution (grabbed from the same 240x240 TFT) with the smoothing diasbled (no anti-aliasing):
 
-2. Frank Boesing has created an extension library for TFT_eSPI that allows a large range of ready-built fonts to be used. Frank's library can be [downloaded here](https://github.com/FrankBoesing/TFT_eSPI_ext). More than 3300 additional Fonts are [available here](https://github.com/FrankBoesing/fonts/tree/master/ofl). The TFT_eSPI_ext library contains examples that demonstrate the use of the fonts.

+2. An excellent new compatible library is available which can render TrueType fonts on a TFT screen (or into a sprite). This has been developed by [takkaO](https://github.com/takkaO/OpenFontRender), I have created a branch with some bug fixes [here](https://github.com/Bodmer/OpenFontRender). The library provides access to compact font files, with fully scaleable anti-aliased glyphs. Left, middle and right justified text can also be printed to the screen. I have added TFT_eSPI specific examples to the OpenFontRender library and tested on RP2040 and ESP32 processors, the ESP8266 does not have sufficient RAM due to the glyph render complexity. Here is a demo screen where a single 12kbyte font file binary was used to render fully anti-aliased glyphs of gradually increasing size on a 320x480 TFT screen:
+

+
+3. New GUI examples have been added for sliders, buttons, graphs and meters. These examples require a new support library here:
+
+   [TFT_eWidget](https://github.com/Bodmer/TFT_eWidget)
+
+4. Support has been added in v2.4.70 for the RP2040 with 16 bit parallel displays. This has been tested and the screen update performance is very good (4ms to clear 320 x 480 screen with HC8357C). The use of the RP2040 PIO makes it easy to change the write cycle timing for different displays. DMA with 16 bit transfers is also supported.
+
+5. Support for the ESP32-S2, ESP32-S3 and ESP32-C3 has been added (DMA only on ESP32 S3 at the moment). Tested with v2.0.3 RC1 of the ESP32 board package. Example setups:

+
+6. Smooth fonts can now be rendered direct to the TFT with very little flicker for quickly changing values. This is achieved by a line-by-line and block-by-block update of the glyph area without drawing pixels twice. This is a "breaking" change for some sketches because a new true/false parameter is needed to render the background. The default is false if the parameter is missing, Examples:
+
+      tft.setTextColor(TFT_WHITE, TFT_BLUE, true);
+      spr.setTextColor(TFT_BLUE, TFT_BLACK, true);
+
+Note: background rendering for Smooth fonts is also now available when using the print stream e.g. with: tft.println("Hello World");
+
+7. New anti-aliased graphics functions to draw lines, wedge shaped lines, circles and rounded rectangles. [Examples are included](https://github.com/Bodmer/TFT_eSPI/tree/master/examples/Smooth%20Graphics). Examples have also been added to [display PNG compressed images](https://github.com/Bodmer/TFT_eSPI/tree/master/examples/PNG%20Images) (note: requires ~40kbytes RAM).
+
+8. Frank Boesing has created an extension library for TFT_eSPI that allows a large range of ready-built fonts to be used. Frank's library (adapted to permit rendering in sprites as well as TFT) can be [downloaded here](https://github.com/Bodmer/TFT_eSPI_ext). More than 3300 additional Fonts are [available here](https://github.com/FrankBoesing/fonts/tree/master/ofl). The TFT_eSPI_ext library contains examples that demonstrate the use of the fonts.

The coordinate datum by default moves to the top left corner of the viewport, but can optionally remain at top left corner of TFT. The GUIslice library will make use of this feature to speed up the rendering of GUI objects ([see #769](https://github.com/Bodmer/TFT_eSPI/issues/769)).

+For other processors only SPI interface displays are supported and the slower Arduino SPI library functions are used by the library. Higher clock speed processors such as used for the Teensy 3.x and 4.x boards will still provide a very good performance with the generic Arduino SPI functions.
 
 "Four wire" SPI and 8 bit parallel interfaces are supported. Due to lack of GPIO pins the 8 bit parallel interface is NOT supported on the ESP8266. 8 bit parallel interface TFTs  (e.g. UNO format mcufriend shields) can used with the STM32 Nucleo 64/144 range or the UNO format ESP32 (see below for ESP32).

Note that due to design variations between these displays not all RPi displays will work with this library, so purchasing a RPi display of these types solely for use with this library is not recommended.
