I love these displays and use them on all my projects. I"ve bought about 8 so far and can get them to work with either Teensy 3.2 or an Arduino Nano.For operation with a Teensy 3.21. use the from the PJRC--and this lib is very fast connect directly2. for touch use "UTouch.h"3. for SD I use 4. no level shifters needed5. you may need to solder J1 (I do on all my displays)4. if you want to use SD, remove the resistors R1, R2, R3 and solder 0 ohm resistorsFor operation with Auduino Nano1. use the 2. for touch use "UTouch.h"3. for SD I have yet to get an SD to work with graphics due to not enough memory4. no level shifters needed5. you WILL need to solder J1 (I do on all my displays)EDIT as of 12/29/2019 Usage with Arduino connect as usual but power your Arduino with 3.3 volts (just connect 3.3 to the 5V pin on the arduino). Alternatively you can put a 1K series resistor on all pins to drop the voltage going to the unit (and power with 3v3). THESE UNITS WILL NOT WORK IF POWERED WITH 5 AND IF THE SIGNAL LINES ARE 5 VOLTS.update 2/2/2022 tips on usage to get everything working on a teensy 4.0 (or 3.2)/* This simple program will test 1) the display, 2) the SD card, 3) the touch screen, 4) ability to readPixel The readPixel is only supported by some display drivers like the ILI9341_t3 driver, there is a PrintScreen.h utility that will let you save your screen to a BMP file and draw the file if readPixel fails try to adjust speeds above. It"s possible the display MISO is not tri state and will basically own MISO where other devices can"t use it.

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! 240×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. We also have a version of this display breakout with a capacitive touchscreen.

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 our resistive touchscreen controller (not included) to use I2C or SPI

We wrapped up this display into an easy-to-use breakout board, with SPI connections on one end and 8-bit on the other. Both are 3-5V compliant with high-speed level shifters so you can use with any microcontroller. If you’re going with SPI mode, you can also take advantage of the onboard MicroSD card socket to display images. (microSD card not included, but any will work)

Of course, we wouldn’t just leave you with a datasheet and a “good luck!”. For 8-bit interface fans we’ve written a full open source graphics library that can draw pixels, lines, rectangles, circles, text, and more. For SPI users, we have a library as well, its separate from the 8-bit library since both versions are heavily optimized. We also have 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 our TFT shield version of this same display, with SPI control and a touch screen controller as well

8 bit digital interface, plus 4 or 5 control lines (12 pins minimum) or SPI mode with 4 or 5 SPI data/control lines (4 pins minimum) – not including the touch screen.

※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.
