I assume you mean the "New Liquidcrystal library" which is a replacement for, not an accessory to, the library that comes with the Arduino IDE. You must follow the installation instructions for this library which you can get here. I believe they also come packaged with the library. Basically you have to remove all traces of any other LiquidCrystal libraries for this one to compile.

I assume that you are referring to this ArduinoInfo page, and to the device he calls "I2C LCD DISPLAY VERSION 1:" That tutorial is actually the one I used when I was tinkering with my adapter which looks like that one and also came on a slow boat from the far east, Banggood in my case.

You also have to deal with the connections between the chip on the IC and the pins that go to the LCD module. These are specific to each pc board and the tutorial gives you the constructor that goes with each of the boards pictured. There is a "guesser" sketch available here if you want to go that route.

I"m looking for a transflective B&W dot matrix LCD screen with a high resolution (~480x320 pixels, ~7x12cm). I"m trying to recreate a device I purchased ~10 years ago, and the screen is a key component. I"ve looked around for a screen that would fit my requirements, but all I can find are backlit color screens, which take way too much power, or e-reader screens, where the refresh rate is far too slow. I"ve also found much smaller transflective LCD screens, but I want a big one!

I would like to recreate my favorite electronic device ever: a Casio Ex-word electronic dictionary from ~10 years ago (the dictionaries were much snappier before they switched to full-color screen models). You can see what this device looks like here: Casio XD-GW9600 Setup Video - YouTube. It"s basically a small computer; it has a keyboard, a small touch LCD for writing in Chinese characters, and a 480x320 dot matrix transflective LCD for browsing dictionaries. Even with constant steady use, it lasts many months with just 2 AAA batteries. The size is perfect, and although it"s wider than a smartphone these days, it fits comfortably in the hands and the text is really clear (extra important for viewing Chinese characters!).

Well, so far at least, 40x04 is the largest LCD character display that I"ve seen available to the consumer/hobbyist market. If somebody out there is selling something larger, I"d be interested in seeing tech specs on the hardware.

I presume that, because of economic forces, and the limitations of 4-bit / 8-bit address lines, the next logical step up would actually be an LCD or OLED graphics display panel; which would, of course require more resources from the host micro-controller board.

Oh....I almost forgot to mention that, as with the 40x02 displays, you WILL NOT be able to use the run-of-the-mill i2c / SPI character LCD backpack boards to simplify the addressing scheme from the controller board to the display itself. Most of those top-out at 20x04.

The Arduino board has a wide variety of compatible displays that you can use in your electronic projects. In most projects, it’s very useful to give the user some sort of feedback from the Arduino.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

Many drawing and writing primitives are provided: single pixel plotting, lines, circles, triangles, rectangles (with square and rounded corners), and corresponding filled shapes. Text and numeric values, may be placed anywhere on the screen in a variety of sizes. Bitmapped shapes can be scrolled or moved about the screen and the whole screen can be rotated.

Points are defined by their Cartesian co-ordinates, (x, y). The origin (0, 0) is at the top left of the screen. Increasing the y value moves down the screen. The addressable dimensions of the SSD1306 screen are 128 pixels left to right (0, 1, 2, …, 127) and 64 pixels from top to bottom (0, 1, 2, …, 63). The pixel in the bottom right corner is (127, 63).

None of these instructions will produce a change on the screen without a display.display(); method. If your script does not appear to be working check you have included this line at the bottom of your screen changing code.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (9" diagonal) bright (30 white-LED backlight) and colorfu 800x480 pixels with individual pixel control. As a bonus, this display has a optional capacitive touch panel with controller GT911 and resistive touch panel with controller XPT2046 attached by default.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (Due/Mega 2560). This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs..

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

For 9 inch screen,the high current is needed.But the current of arduino uno or arduino mega board is low, an external 5V power supply is needed. Refer to the image shows the external power supply position on shield ER-AS-SSD1963.

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.
