arduino due tft display quotation
Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (12 white-LED backlight) and colorful 480x272 pixels with individual pixel control. As a bonus, this display has a capacitive touch panel attached on screen 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 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!
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.
1st Arduino project, beyond the very basic intros, and no coding experience before this endeavor, so I"m sure I"m just not searching the right things/way to figure this out.
The project - replacing gauges in my truck with Arduino+TFT display. As a starter, I"m working strictly on single fuel gauge functionality, and eventually including dual fuel gauges (2 separate fuel tanks in truck), voltage gauge, coolant temp gauge, and GPS driven speedometer. Yeah...I"m already realizing I"m in for a bit of a steep learning curve here, lol.
The setup - Genuine Arduino Mega 2560, Seeed Studio 2.8" touchscreen sheild V1.0, aftermarket universal style fuel sender. Sender is connected to Analog pin 9 through a voltage divider circuit running roughly 1.5VDC-4.95VDC, and I get appropriate numbers from the serial monitor when cycling the sender. I"m not currently utilizing the touch features of the screen, though I may in the future. RIght now it"s strictly a display device. I did find out how to modify the TFT.h file to get the display to function on the Mega board, and am writing static text to it currently.
The problem - how the heck do I get the value read from the Analog pin to display on the screen? I"ve spent the last couple of days searching the forums here and on Adafruit, as well as various other sites found on Google. I"ve spent hours looking at other"s code to try and figure this out, but not being a coder before this, I"m finding it difficult to determine which parts of the code are relevant to what I"m attempting to do, and I think I may be confusing myself/WAY overthinking it, lol. It seems like it should be a simple thing...
That part I"m good with, but I can"t figure out how to get a value read from the analog pins to display as numbers on the screen. I"m not looking to be spoon fed the answers, but if I could maybe get some guidance on what functions I"m missing, or what I should be searching for to figure this out?
I know that the TFT is not faulty, because I used it on an Arduino Uno using a different library, and it worked just fine. The problem with this library is that it only works on AVR processors, and as you know, the due uses an ARM processor. Does anyone know how to get something to show on screen? I would be ok with losing the sd card reader and maybe touch, but those would be a plus to keep! Thanks for reading!
Oh, I"m not worried about the board"s electrical compatibility, its just that the current Due modifications to the UTFT Library only work with the 16 bit models of LCD. I am curious what I would need to modify in the library to get my 8 Bit LCD running properly.
I"m sorry, there seems to be a mixup.. I was replying to a post that now appears to be gone (it was regarding a shield that simplified wiring a TFT to a MEGA).

I found this Shield http://imall.iteadstudio.com/development-platform/arduino/shields/im120417024.html that works with Boards with 3.3V or 5V so it would make it easy to use an TFT with the UTFT Lib and dimdim"s modifications. So you have the tft and the touch function together.
I wired it up according to UTFT"s documentation, adapting it to the specific TFT. It was not difficult. I should point out that it is an ITDB32WD compatible display that I got off of ebay, and not an ITead original.
The display works natively with 3.3V logic (I had to use resistors to use it with the older Arduinos) so it is actually easier to interface to the Due than to older Arduinos.
I try to convert the UFT Clock from Henning Karlsen to work with the Due Electronics - Henning Karlsen. But my Calender is blinking the clock is working proper.
I don"t use the UTFT library, but I have a sainsmart TFT shield with a mega using an SSD1289. I"m interested to see how it compares to the Due implementation.
then what Library are you using? I also have a Mega and a TFT display, but it takes about a second to clear the screen! I would love to have it run faster!
also, I hope this gets noticed by the creator of the UTFT library, who wants to port it to the Due but can"t because he doesn"t yet own one. I guess this would make porting a whole lot easier.
Here"s one more thing, when using samples (or doing your own) - you need to change bitmap definitions a bit to make it work.. For example, tux.c in UTFT_Rotate_Bitmap example:
Yes, but you need to get itdb02_32s display and mega shield for it from iteadstudio.com, these sources are compatible with that display and propably only with that display, other than 16bit modes are removed and this library only supports arduino due as I replaced and removed code, instead of just making it compatible with due along others. But here"s a library, examples work "as is" with mega pins chosen on utft init..

I"m having a go at building my own driver, the mainstream libraries are too slow for games and interactivity. They all suffer a similar overhead with respect to being portable between uC"s and compatible with multiple devices. Whereas I"ve targeted my code directly to the 2560 and the display. I"ll post the code on the forums eventually.

I"ll probably post the code in the display forum. If you would like to see its current performance, I have posted a video here: http://arduino.cc/forum/index.php/topic,140111.0.html
I"ll also post any info on the library there. Remember my info was for a Mega 2560, not the Due. Although I guess its a good reference to see what we can expect at a minimum from the Due.
Just wondering as I"m working on a DSP/DAC project and arduino due is the controller of choice running the Hifiduino code for now until I learn how to code.
I have been poking around with it and sort of have the one from seedstudio working, The library would like to just write the data to the register but the due registers are all in different places in due so i made it digital read and digital write. Lots of overhead and poor performance. Was quite shocked it sort of worked at all. The touch screen was not at all hard to make work, but the tft is a nightmare.
From the picture of the kit you provided on ebay, the flash ic appears to be absent, indeed I understand it to be a little "hit and miss" as to whether you have the ic or not. You can check, look if there is an ic soldered on the 8 pin pad at the side of the SD cage on the rear of TFT.
The TFT/SD Shield for arduino DUE is shipped with the following jumper config, if you use TFT modules in our store, you do not need to reconfig the jumpers.
Be warned!! tinyFAT and UTFT_tinyFAT take some doing to get working successfuly, as there are just so many variables. SPI Speed can be a big issue with several newer SD cards and quality of level shifters if required.
The touchscreen size issue, I am aware of but not familiar with, as I do not have the SD1963 version of this display, mine is the CPLD version, I suspect I am not able to assist you further.
Also, as a final comment, maybe worth mentioning some people have had problems with the 7" displays if you are relying completely on USB power, you should also use external wall power adaptor (9V 1A).
I am trying to use TFT LCD Display ILI9486/ILI9488 480x320 with Arduino Due. The display is showing blank white screen. My test program compiles and uploads without any error. However, LCD display remains blank with white screen.
Yes, Chinese Vendors tend to package hacked versions of old libraries. e.g. this seems to be based on UTFT v2.79 and UTouch has now been replaced by URTouch.
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.
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.
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.
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:
Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.
This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.
The module is compatible with either of the Arduino Uno or the Arduino Mega, so feel free to choose between them or test with both. As usual, these components can be bought via the links attached to them.
One of the good things about this module is the ease with which it can be connected to either of the Arduino Mega or Uno. For this tutorial, we will use the Arduino Uno, since the module comes as a shield with pins soldered to match the Uno’s pinout. All we need to do is snap it onto the top of the Arduino Uno as shown in the image below, thus no wiring required.
This ease of using the module mentioned above is, however, one of the few downsides of the display. If we do not use the attached SD card slot, we will be left with 6 digital and one analog pin as the module use the majority of the Arduino pins. When we use the SD card part of the display, we will be left with just 2 digital and one analog pin which at times limits the kind of project in which we can use this display. This is one of the reasons while the compatibility of this display with the Arduino Mega is such a good news, as the “Mega” offers more digital and analog pins to work with, so when you need extra pins, and size is not an issue, use the Mega.
To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.
As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.
With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).
Next is the void loop() function. Here we basically create a UI to display the youtube subscribe button, using some of the same functions we used under the void setup() function.
The Adafruit library helps reduce the amount of work one needs to do while developing the code for this display, leaving the quality of the user interface to the limitations of the creativity and imagination of the person writing the code.

In case anyone is interested, I want to use some of these ILI9341/0 displays on both Teensy based stuff as well as Arduino (actually an Atmega644 based board) based system, and I still want the ability to read pixels. In particular where I am wanting this is for Debug text output where I can scroll the text...
I adapted the read pixel test program mentioned earlier in this thread (could not use printf on stream, change library name...) and so far it appears to work on a Teensy 3.1 with PJRC ILI9341 display as well as on an Arbotix-M board (Atmega 644p) using Adafruit 2.2" TFT display (ILI9340). So should work fine on Atmega328p based systems as well. I have not tested it on an Arduino Due yet. I have one buried around here somewhere
