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. 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.
2. Support for HX8357B and HX8357C screens has been added (only tested with RP2040 and 16 bit parallel interface)
3. Support for the ESP32-S3 and ESP32-C3 has been added (DMA not support at the moment). Tested with v2.0.3 RC1 of the ESP32 board package. Example setups:
[Setup70_ESP32_S2_ILI9341.h](https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setups/Setup70_ESP32_S2_ILI9341.h)
[Setup70b_ESP32_S3_ILI9341.h](https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setups/Setup70b_ESP32_S3_ILI9341.h)
[Setup70c_ESP32_C3_ILI9341.h](https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setups/Setup70c_ESP32_C3_ILI9341.h)
[Setup70d_ILI9488_S3_Parallel.h](https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setups/Setup70d_ILI9488_S3_Parallel.h)
4. 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");
5. 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).
6. 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.
7. Users of PowerPoint experienced with running macros may be interested in the [pptm sketch generator here](https://github.com/Bodmer/PowerPoint_to_sketch), this converts graphics and tables drawn in PowerPoint slides into an Arduino sketch that renders the graphics on a 480x320 TFT. This is based on VB macros [created by Kris Kasprzak here](https://github.com/KrisKasprzak/Powerpoint-ILI9341_t3).
8. The library contains two new functions for rectangles filled with a horizontal or vertical coloured gradient:
tft.fillRectHGradient(x, y, w, h, color1, color2);
tft.fillRectVGradient(x, y, w, h, color1, color2);
9. The RP2040 8 bit parallel interface uses the PIO. The PIO now manages the "setWindow" and "block fill" actions, releasing the processor for other tasks when areas of the screen are being filled with a colour. The PIO can optionally be used for SPI interface displays if #define RP2040_PIO_SPI is put in the setup file. Touch screens and pixel read operations are not supported when the PIO interface is used.
The RP2040 PIO features only work with [Earle Philhower's board package](https://github.com/earlephilhower/arduino-pico), NOT the Arduino Mbed version.
The use of PIO for SPI allows the RP2040 to be over-clocked (up to 250MHz works on my boards) in Earle's board package whilst still maintaining high SPI clock rates.
10. DMA can now be used with the Raspberry Pi Pico (RP2040) when used with both 8 bit parallel and 16 bit colour SPI displays. See "Bouncy_Circles" sketch.

11. The library now supports the Raspberry Pi Pico with both the [official Arduino board package](https://github.com/arduino/ArduinoCore-mbed) and the one provided by [Earle Philhower](https://github.com/earlephilhower/arduino-pico). The setup file "Setup60_RP2040_ILI9341.h" has been used for tests with an ILI9341 display. At the moment only SPI interface displays have been tested. SPI port 0 is the default but SPI port 1 can be specifed in the setup file if those SPI pins are used.
["Rotating cube demo"](https://www.youtube.com/watch?v=4fPxEN9ImVE)
12. The library now provides a "viewport" capability. See "Viewport_Demo" and "Viewport_graphicstest" examples. When a viewport is defined graphics will only appear within that window. 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)).
# TFT_eSPI
An Arduino IDE compatible graphics and fonts library for 32 bit processors. The library is targeted at 32 bit processors, it has been performance optimised for STM32, ESP8266 and ESP32 types. The library can be loaded using the Arduino IDE's Library Manager. Direct Memory Access (DMA) can be used with the ESP32, RP2040 and STM32 processors with SPI interface displays to improve rendering performance. DMA with a parallel interface is only supported with the RP2040.
Optimised drivers are incorporated for the following processors:
* RP2040, e.g. Raspberry Pi Pico
* ESP32 and ESP32-S2, ESP32-C3, ESP32-S3
* ESP8266
* STM32F1xx, STM32F2xx, STM32F4xx, STM32F767 (higher RAM processors recommended)
Generic (non-optimised Arduino function calls) are used by the library for other processors.
"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).
Displays using the following controllers are supported:
* GC9A01
* ILI9163
* ILI9225
* ILI9341
* ILI9342
* ILI9481 (DMA not supported with SPI)
* ILI9486 (DMA not supported with SPI)
* ILI9488 (DMA not supported with SPI)
* HX8357B (16 bit parallel tested with RP2040)
* HX8357C (16 bit parallel tested with RP2040)
* HX8357D
* R61581
* RM68120 (support files added but untested)
* RM68140
* S6D02A1
* SSD1351
* SSD1963
* ST7735
* ST7789
* ST7796
ILI9341 and ST7796 SPI based displays are recommended as starting point for experimenting with this library.
The library supports some TFT displays designed for the Raspberry Pi (RPi) that are based on a ILI9486 or ST7796 driver chip with a 480 x 320 pixel screen. The ILI9486 RPi display must be of the Waveshare design and use a 16 bit serial interface based on the 74HC04, 74HC4040 and 2 x 74HC4094 logic chips. 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.
A "good" RPi display is the [MHS-4.0 inch Display-B type ST7796](http://www.lcdwiki.com/MHS-4.0inch_Display-B) which provides good performance. This has a dedicated controller and can be clocked at up to 80MHz with the ESP32 (55MHz with STM32 and 40MHz with ESP8266). The [MHS-3.5 inch RPi
