Check this out if you are using Raspberry Pi, it is the cutest little display that you can stack on your Raspberry Pi Single Board Computer. It features a 2.8" display with 320 x 240 16-bit color pixels and a resistive touch overlay. The plate uses the high-speed SPI interface on the GPIO pins. You can use the mini display as a console, X window port, displaying images or video, etc. Best of all it plugs right in on top!
It's designed to fit nicely onto the:
Uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. All other GPIO are unused. Since we had a tiny bit of space, there are 4 spots for optional slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.
Pin Assignment:
- Pin 1 & 17: 3.3V: Power positive (3.3V power input)
- Pin 2 & 4: 5V: Power positive (5V power input)
- Pin 3, 5, 7, 8, 10, 22: NC: Not Connected
- Pin 6, 9, 14, 20, 25: GND: Ground
- Pin 11: TP_IRQ: Touch Panel interrupt, low level while the Touch Panel detects touching
- Pin 12: KEY1: Key, the push button with a label of K1, side of LCD
- Pin 13: RST: Reset
- Pin 15: LCD_RS: LCD instruction control, Instruction/Data Register selection
- Pin 16: KEY2: Key, the push button with a label of K2, side of LCD
- Pin 18: KEY3: Key, the push button with a label of K3, side of LCD
- Pin 19: LCD_SI / TP_SI: SPI data input of LCD/Touch Panel
- Pin 21: TP_SO: SPI data output of Touch Panel
- Pin 23: LCD_SCK / TP_SCK: SPI clock of LCD/Touch Panel
- Pin 24: LCD_CS: LCD chip selection, low active
- Pin 26: TP_CS: Touch Panel chip selection, low active
It comes fully assembled and ready to be stacked onto your Pi! No soldering is required.
Adafruit has created a custom kernel package based on Notro's awesome framebuffer work, so you can install it over your existing Raspbian (or derivative) images in just a few commands. This tutorial shows you how to install the software, as well as calibrate the touchscreen, show videos, display images such as from your PiCam, and more!
Alternatively, we have tried installing the Graphics driver from LCD wiki page and is provided for Raspberry Pi OS/Raspbian. It also supports Ubuntu and Kali Linux too. Do follow the steps here: www.lcdwiki.com/2.8inch_RPi_Display
Note: Please use the recommended system for the touch screen. If another system is used, it may not have the touch function or may not work. You need to configure it yourself. Because there are many systems that the Raspberry Pi can use, we can’t make every system compatible with the touch screen.
