A 2.8" color display to plug on the Raspberry-Pi GPIO
Need a nice little display for Raspberry-Pi? This is the PiTFT Plus 2.8".
It consists of a 2.8" display (71mm diagonal) with a resolution of 320x240 in 16-bit color and a resistive film to make a touch screen.
This card uses the Pi's high speed SPI interface and can be used as a mini display console, X Window port, image or video display, etc. The best left for the end, you simply plug it into the GPIO of your Raspberry-Pi!
This version of the PiTFT 2.8" is updated to perfectly match the Pi Zero, Pi 3, Pi2 or A+ and B+ (all Pi with a 2x20 connector). Not suitable for older Pi 1 with 2x13 connector.
This card is also equipped with a 40-pin male connector under the card to connect a GPIO ribbon to connect a Cobbler.
The display and the touch panel use the pins of the SPI interface (SCK, MOSI, MISO, CE0, CE1) as well as the GPIO #24 and #25. As there remain a little room, Adafruit added 4 buttons connected to 4 GPIO (#17,#22,#23,#27), you can use them to achieve a basic user interface. For example, you can use one of the buttons to control the extinction of the Raspberry-Pi.
You can use this screen to display the X Windows graphical interface, although 320x240 is quite small. We recommend using PyGame or other programs based on SDL (which can write directly in the frame buffer).
GPIO pins used
PiTFT uses the hardware SPI interface pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO pins #24 and #25. All other GPIO pins are available. Pins #17,#22,#23,#27 are connected to the buttons next to the screen. The GPIO pin 18 can be used to control the power of the backlight using a PWM signal.
Additional GPIO breakout The bottom of the card is equipped with an additional connector 2x20 pins (Raspberry-Pi B+) to connect a 40-wire GPIO cable. So, you can also use the other GPIO signals still available.
If you need more GPIO, other inputs/outputs are available under the card breakout (via connection pads that you can weld)
The card is equipped with 4 mounting holes to fix the PiTFT Plus and the Raspberry under a surface (or frame).
This product is delivered assembled ready to be plugged into your Raspberry-Pi:
- A female connector 2x20 pin to connect the card to your Pi 3, Pi 2, A+, B+
- A male connector 2x20 pin to connect an IDC cable or a 2x20 Cobbler to the side of the card or a GPIO 40 ribbon to use your Pi-TFT with your own expansion cards
No need to welded, The PiTFT-PLUS is delivered assembled
Adafruit has developed a Kernal package based on the incredible work of Notro on the FrameBuffer. It is therefore possible to easily install this package on existing (and derived) Raspbian images using a few commands.
See the tutorial below for how to install the software part, calibrate the touch screen, display videos, display images (ex: from the PiCam), etc
