A 3.5" TFT touchscreen drive your Raspberry-Pi embedded applications via the GPIO
Is it not the nicest display for Raspberry Pi? It consists of a 3.5" display (89mm diagonal) supporting a resolution of 480x320 in 16-bit color and a resistive film to make it a touch screen. This version of the PiTFT is designed for the Raspberry Pi (all version with 40 pins GPIOs).
The 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.
You can use this screen to display the X Window graphic interface or your PyGame application. You can also have an HDMI display connected separately.
The best left for the end, this card plugs directly above your Raspberry Pi3, Pi2!
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.
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 2x16 pins (Raspberry-Pi classic) to connect a 26-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 solder)
The card is equipped with 4 small pre-punched extensions. These extensions are equipped with 4 mounting holes to attach the PiTFT Plus and the Raspberry under a surface (or frame). It is also possible to use a clamp to break the pre-punched extensions so that the screen and the Raspberry-Pi are the same size.
This product is delivered assembled ready to be plugged into your Raspberry-Pi:
- A female connector 2x40 pin to connect the card to your Pi 2, A+, B+
- A male connector 2x13 pin to connect an IDC cable or a 2x13 Cobbler to the side of the card or a GPIO 26 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, view videos, display images (ex: from the PiCam), etc.
