A [Beta test branch](https://github.com/Bodmer/TFT_eSPI/tree/2.4.0-Beta) has been created, this has some new anti-aliased line functions (drawSpot, drawWideLine and drawWedgeLine), see the new Anti-aliased_Clock_v3 example. Comments in discussions tab (not issues at the moment please) are welcome.
A new ["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 hase been added for the ESP32 S2 processor variant. A [new user setup](https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setups/Setup70_ESP32_S2_ILI9341.h) file has been added as an example setup with an ILI9341 TFT. You will need to load ESP32 Arduino board package 2.0.0 or later to use the updated library.

3. 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.

# 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 and STM32 processors to improve rendering performance.

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 to improve rendering performance.
Optimised drivers are incorporated for the following processors:
* RP2040, e.g. Raspberry Pi Pico
* ESP32 and ESP32-S2 (ESP32C3 untested)
* 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).

The library supports SPI overlap on the ESP8266 so the TFT screen can share MOSI, MISO and SCLK pins with the program FLASH, this frees up GPIO pins for other uses.

The library contains proportional fonts, different sizes can be enabled/disabled at compile time to optimise the use of FLASH memory. Anti-aliased (smooth) font files in vlw format stored in SPIFFS are supported. Any 16 bit Unicode character can be included and rendered, this means many language specific characters can be rendered to the screen.
The library is based on the Adafruit GFX and Adafruit driver libraries and the aim is to retain compatibility. Significant additions have been made to the library to boost the speed for ESP8266/ESP32 processors (it is typically 3 to 10 times faster) and to add new features. The new graphics functions include different size proportional fonts and formatting features. There are lots of example sketches to demonstrate the different features and included functions.

Configuration of the library font selections, pins used to interface with the TFT and other features is made by editing the User_Setup.h file in the library folder, or by selecting your own configuration in the "User_Setup_Selet,h" file. Fonts and features can easily be enabled/disabled by commenting out lines.
