I am trying to make a truly Universal Remote Control out of this mess. I just got the Arduino Uno & the Display and put it together and there are NO pins left to operate an IR LED.

Can this 2.8" elegoo display play video at all? I"m trying to make a unit that an older woman, in her 80"s can play a video on it, if I set it up correctly? This is for a really good cause, I desperately need help, this is super important. Helping elderly folks with modern technology is tough. But I really need it to be able to play a video off the SD card if possible. Any help would be super highly appreciated.ReplyUpvote

Hello,please post our code also ..the screen driver must be known and that info must be known in order to get these things to work correctly..you show your code and then the vid blurs..Someone needs to write a pdf teaching how ,what ,when and why concerning these screens I would gladly pay $10.00 and I am sure others would too.I have 3 different tftlcds only 1 works its for the mega and Bomer has a lib for it,I am really considering use of Nextion units from now on 4 pins easy programming but higher cost...also the small cell phone screens use spi mode and are real easy to set up and use

The program runs and nothing is displayed but a white screen. when I open the COM4 I see that when I hit the screen numbers appear to calibrate the screens position so it is registering but not showing up on the LCD. please help me before I pull all my hair out.1

Is there any way, with an UNO, to add other I/O, given all the pins are used/covered, and none are brought through? I"d like to interface a 5-pin joystick. Is the only answer "buy a Mega"?ReplyUpvote

I"m thinking I need an Arduino Mega to do what I want - a Universal Remote. Because after mounting the display there are NO pins left for anything else.0

Thank you for the instructable. I"v been trying to build a DIY smartphone but couldn"t get the code or libraries for the touch screen. Now i can finally build it. Thanks.0

I"m having issues getting this display to work on my Arduino 101 board with the libraries that are suggested - errors in compiling seem to indicate that the board type isn"t supported in the Adafruit_TFTLCD library. Here"s a representative error:

I finally got the touchscreen to work correct using your links to the libraries. Found out that this specific TFT display module uses pin 6 & 7 for touch sensor, instead of the standard 4 & 5.0

I never received a response on this, so went through the painful process of copying code from the video. It can be found here for others that might need it. Not that this has some minor changes, but is fully functional and I will continue to refine: https://github.com/siliconghost/Arduino_2.8in_TFT_wSD

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.

i had the same issues with this 3,5" TFT LCD and wiring it to an ESP32 and making the TouchScreen work. However i managed to find a solution to the problem. Lets start with the wiring:

Next lets focus on the software side. In bodmers awesome library you have to comment/uncomment the right sections. The User_Setup.h file is pretty straight forward. My display used the ILI9488 processor and is run in 8 Bit parallel mode:

When it came to the touchscreen i faced some difficulties. Since the display with 8 bit there is no dedicated "Touch Pin" like other displays use. I decided to use a different library than @Bodmer (no front, still love you and the library <3). I used the ADAFRUIT Touchscreen library in extend:

The Touchscreen sends us four different values if wired correctly. The X-Position, Y-Postition aswell as the pressure applied (XM, YM). These values are received via the following pins:

I bought online this LCD Touchscreen Kuman SC3A-NEW-UK. It uses ILI9486 drivers, but it didn"t include any instructions manual, and kumantech.com seems to be devoid of complete technical documentation about SC3A-NEW-UK model.

Just in case it wasn"t noticable: I am trying to make a "Hello World" for my SC3A-NEW-UK"s LCD Touchscreen from an Arduino UNO board. In other words: just print "Hello World" to see if it works.

This compiled in Arduino IDE, no problem, but I still don"t know if it will work well with my screen. I am also confused about initialization of the TFT object and how would I have to wire the LCD screen to the Arduino depending on this initialization:

...i mean, my LCD screen has CS and RESET pins, but what is DC supposed to be here? (in this context, I don"t think it stands for "Direct Current"... but there"s no DC pin reference in my LCD screen written "AS IS"... ?? This brings me more confusion...

...specially having in mind that I don"t know how am I supposed to wire the LCD screen to the Arduino yet. It seems the LCD pins have been designed to fit in directly to the Arduino board without thinking too much about it (like the shape is the same), but that would make the screen getting all the Arduino UNO"s pins for itself, so I don"t think so...

...so, powering the screen shouldn"t be a big deal, but, how am I supposed to connect everything else? I am completely misguided about how am I supposed to interact with the screen from Arduino code... what is RS pin for? Should I use 4-bit or 8-bit mode? (I think 4-bit would imply connecting 4 digital pins for the screen, and 8-bit the whole 8 pins from screen to the Arduino UNO board)? Should I use LCD_RD and LCD_WR? Well you have a picture of my confusion.

Even though I know how to control Input/Output in Arduino code to interact with analog/digital input and output pins at will with C++ in Arduino code (but even so, I think I"m still an Arduino n00b), this LCD screen"s physical interface is very confusing to me...

PD: I have read somewhere that this SC3A-NEW-UK Touchscreen is made to shield Arduino MEGA boards (by fitting the PINs directly into it), but mine is an Arduino UNO Board! (perhaps I shouldn"t have bought This LCD model, then?)... but I have sets of wires, pinboards and stuff... I don"t want to give up the idea of harnessing this LCD screen using an Arduino UNO. I don"t care about shielding feature, I just want to wire it and make it work. I will figure out how to shield electronics later on.

Based on VE7JRO"s answer, I managed to map the connections by seeing where the connections would go if I just fit the connections shielding the Arduino UNO, the way VE7JRO suggested:

I put NONE for A5 input, because that pin of LCD screen doesn"t have any name on it. There are another ones without name as well, that I didn"t include in this table. I believe (perhaps I"m wrong believing it, I don"t know) that those pins without name have no use.

The bad thing about this layout is that it consumes almost all the Arduino pins, so I would not be able to attach additional circuits. However, perhaps I should not be worrying about earning connections yet, before testing the screen.

I still don"t know much of the details about what pins do what for the screen, but I have read somewhere that LCD_D0 to LCD_D7 are meant to receive digital data in some kind of 8-bit parallel mode. But I also heard that there is a 4-bit mode. If I could use that mode with this screen, I would be able to have 4 free digital pins for anything else...

I tested VE7JRO"s code. LCD Screen did draw the interface as expected. But buttons didn"t respond. I found out the code sample needs further calibration.

...because their values when I touch the screen with the touchpen are very weird. I tried to guess which ranges they go, and they don"t make sense when I move around the screen. Perhaps it"s because this strange "Z instead of Y" mapping from the TSPoint object. Perhaps pixel_x and pixel_y don"t need to make an intuitive sense, perhaps it"s just some intrincated in-bound logic that only makes sense within electronics" low-level scope, or within Adafruit_GFX_Button.press method, I don"t know... but x, y and z readings from TSPoint object seem very accurate, despite Y being Z and Z being Y...

There are 22 test sketches that come with the MCUFRIEND_kbv library. One of them scans your display and outputs configuration information (sorry, it"s been a while since I tested my screen). Another sketch will draw little boxes in each corner and sides. This is used to get the x y coordinates of the edges of your particular screen (it might be called TouchScreen_Calibr_native.ino).

z seems indeed sensitive to touch pressure, but it"s like its sensitivity is different depending on the touchpen"s position on screen (altough I"m not a robot, I think I was using more or less the same amount of force with my hand). It prints 0 when i do not touch the screen.

The fifth parameter is supposed to be the resistance measured between LCD_D6 and LCD_RS with the screen unplugged. Unfortunately, my multimeter can"t measure it for some reason (I put it in 2000 Ohms mode for reading resistance: I always get "1", the same than when I don"t connect anything... like if multimeter"s contacts aren"t working well, I don"t know)... so I left the default 300 value.
