adafruit 2.8 tft lcd touchscreen quotation

With four bright white LED backlight and 240 x 320 pixels with individual RGB pixel control, this colour 2.8in. TFT display features a resistive touchscreen for fingertip detection across the entire screen surface. The workload is lifted from the microcontroller by a built-in controller equipped with RAM buffering, and the display board has two modes: 8-bit and SPI.

Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful! 240x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. The display can be used in two modes: 8-bit and SPI. For 8-bit mode, you"ll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than 8-bit mode. In addition, 4 pins are required for the touch screen (2 digital, 2 analog) or you can purchase and use the resistive touchscreen controller (not included) to use I2C or SPI

Of course, Adafruit wouldn"t just leave you with a datasheet and a "good luck!". For 8-bit interface fans they"ve written a full open source graphics library that can draw pixels, lines, rectangles, circles, text, and more. For SPI users, there is a library as well, its separate from the 8-bit library since both versions are heavily optimized. There is also a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it.

If you are using an Arduino-shaped microcontroller, check out the TFT shield version of this same display, with SPI control and a touch screen controller as well

The Adafruit 2.8in. TFT LCD Touchscreen Display brings QVGA graphics to your next project using only 5 x SPI pins or 12 x GPIO pins if you can spare them. The screen is bright with a 4-LED backlight and can display 18-bits of colour (262,000 colours). There"s a display controller built in so your microcontroller doesn"t need to get involved in refreshing the screen, it just has to write the pixels once then it can move on to other tasks. SPI mode uses less pins but is slower while 8-bit mode uses more pins and is faster, the choice is up to you. Adafruit have software and tutorials to support you whichever mode you decide to use, see the links below. The board also has a micro-SD card socket that you can use to store files and images.

Visit https://learn.adafruit.com where Adafruit provide a free tutorial for the Raspberry Pi, and another tutorial for the Arduino. They also have an open source library to drive the display in 8-bit mode, and another to use SPI mode. Please note that while the screen is capable of 18-bit colour, the Adafruit code uses 16-bits for efficiency. It"s highly unlikely that you"ll ever notice any difference.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 2.8"TFT Touch Shield with Libraries, EXxamples.Schematic Diagram for Arduino Due,Mega 2560 and Uno . For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

The 2.8" Resistive Touchscreen by Adafruit comes in the form of a shield to help you set up your Arduino projects. It has a high-quality display for immediately viewing your data: images, e-mails, text messages and information of a more technical nature are all perfectly legible!

The shield has a pleasant-sized TFT screen (2.8” diagonal) offering a vast choice of colours with 262,000 shades available in 18-bit mode and a great brightness thanks to a backlight with 4 white LEDs, which can be controlled with a digital pin connection.

In this case, the TFT resistive touchscreen proposed by Adafruit is a true plug-and-play screen; already assembled and tested, it’s ready for use in just 10 minutes after downloading an Arduino code library.

The screen uses digital pins 13-9, the touchscreen controller requires digital pin 8, the microSD pin requires digital pin 4; you can use digital pins 2, 3, 5, 6, 7 and analogue pins 0-5, and pin 4 will also be available if you don’t use the microSD connection

Add some sizzle to your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection and a capacitive touchscreen. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This shield is the capacitive version as opposed to the resistive touchscreen we also sell. This touchscreen doesn"t require pressing down on the screen with a stylus, and has a nice glossy glass cover. It is a single-touch display.

This shield uses SPI for the display and SD card and is easier to use with UNO, Mega & Leonardo Arduino"s. The capacitive touchscreen controller uses I2C but you can share the I2C bus with other I2C devices.

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield needs fewer pins than our v1 shield, so you can connect more sensors, buttons and LEDs: 5 SPI pins for the display, 2 shared I2C pins for the touchscreen controller and another pin for uSD card if you want to read images off of it.

The display uses digital pins 13-9. Touchscreen controller requires I2C pins SDA and SCL. microSD pin requires digital #4. That means you can use digital pins 2, 3, 5, 6, 7, 8 and analog 0-5. Pin 4 is available if not using the microSD
