320*240 (2.8'') Touch screen in 16-bit color for Arduino and PyBoard
Warning: Last items in stock!
Spice up your Arduino or PyBoard projects with this beautiful touchscreen equipped with a connection for micro SD. This shield is a large TFT display (2.8 inches diagonal), bright (backlit in white light with 4 LEDs) and very colorful (262.000 different colors - 18-bit)! Each of the 240x320 pixels can be individually controlled, which in the end offers a much better resolution than the 128x64 displays in black and white (mobile phone screen type).
As a bonus, this screen is already equipped with a resistive tactile film. It is therefore possible to detect the finger pressure anywhere on the screen.
MicroPython PyBoard compatibility:
This TFT screen is equipped with an ILI9341 driver supported on the PyBoard by Roman Podgaiski's library. We offer a tutorial for your PyBoard (with connection diagram). At the moment, only the TFT is supported (the tactile part STMPE610 is not yet supported on the PyBoard)
Really cool improvements:
This new version is now equipped with a display and SPI controller - if it decreases the speed a bit, on the other hand this approach has the advantage of using a lot less pins and allows the shield to be used much more easily with an Arduino Mega and a Leonardo.
That's not all, the touchscreen controller has also gone into SPI, so you only need an extra pin to use this quality sensory controller.
Even with all these additions, the AdaFruit engineers have managed to control the costs to continue to propose the shield at an affordable price!
This shield is completely assembled, tested and ready to use. No need for wire or welding iron! Plug it in and use our library - operational in 10 minutes! Works best with a classic Arduino (UNO/Duemilanove/Diecimila). Weld 3 jumpers (pellets) will also allow you to use it at full speed with an Arduino Leonardo or Mega. This shield can be used on an Arduino Yun using the Arduino Leonardo configuration (see the discussions on the AdaFruit Forums before proceeding with your purchase).
This display has its own controller equipped with its buffer memory (RAM). Thanks to this, the micro-controller is almost not solicited. This shield requires fewer pins than version 1, which allows to connect more sensors, buttons and LEDs.
This shield is not delivered with a simple Data Sheet - AdaFruit has developed an Open Source graphic library that can draw pixels, lines, rectangles, circles and text. There is also a touch screen library that detects the x, y and z (pressure) coordinates as well as a example code that demonstrates the operation of all these features. This source code is written for an Arduino but could easily be ported to your favorite micro-controller.
This means that digital pins 2, 3, 5, 6, 7 and analog 0 to 5 are available.
Pin 4 is available if you don't use the micro SD drive.
