Welcome to another Arduino video tutorial! In this video, we are going to take a first look at this 2. It is a big, low-cost touch display which is very easy to use.метеостанция esp32 + 2 дисплея (esp32+2tft 320x240) ч.4
Hello guys, I am Nick and welcome to educ8s. If you are new here, welcome, be sure to subscribe and check the previous videos on the channel. Today we are going to learn how to drive the 2. Compared to one of my favorites displays, the 1. The screen also offers touch functionality which is an added bonus and an SD card slot at the back. It uses the SPI interface, so the connection with the Arduino is very straightforward.
Full disclosure: All of the links above are affiliate links. I get a small percentage of each sale they generate. Thank you for your support! Another thing I like about this display is that it does not come as a shield like the touch display we were using so far. This is very important because we now have a low-cost display that we can use with every board.
The first 9 pins of the display are the power pins and the SPI pins. So, if we connect only the first 9 pins of the display, we can use it as a regular display without touch functionality. The display uses 3. So, we need to use some 10K resistors if we want to drive it with a board that uses 5V logic levels like the Arduino Uno.
Arduino and the 2. But as you can see it is very slow in updating the screen.
Quickie: SD Cards with Arduino
It takes many seconds to update the whole screen which is a pity. It can display text with more speed though. It is obvious that the Arduino Uno is not enough to drive a display with such a high resolution.
It is obvious that we need a more powerful board to drive this display effectively.
But can we build a useful project using this display? I wanted to find out, so I decided to build a simple real-time clock and temperature monitor. You can find the code of the project in a link in the description below. The result is not that bad as the demo sketch. The project works fine, but of course, there is a small delay when the values on the screen are updated. In my opinion, this project demonstrates that we can use this display with an 8bit Arduino only on very simple projects that update the screen rarely.
We connect the remaining 5 pins according to this schematic diagram, and we are ready to upload the second sketch to the board. To my surprise, the touch demo works relatively fast! It is a simple sketch in which we draw on the screen using this stylus.
I think this result is impressive if we take into consideration that this display is driven by an 8bit board.
If you are not familiar with it, the ESP32 is a very fast and inexpensive Arduino compatible board.The system also includes a ILI 2. Despite its outward appearance, this project is very much beginner friendly. Much like the HestiaPi project we covered a few months backthis project takes a cheap and readily available development board and turns it into something that has all the trappings of a commercial offering.
These projects are reminders that the line between built and bought is only getting blurrier as time goes on. The ESP family of microcontrollers is absolutely on fire right now, with a decent chunk of the projects that come our way now based on one of the impossibly cheap WiFi-enabled boards. The end result is a bunch of projects in which the ESP is simply underutilized.
But we can assure you this ESP32 alarm clock created by [Pangodream] is absolutely not one of them. From DIY touch sensors to the Android application used to configure the clock over the network, this project is overflowing with neat hardware and software tricks worth taking a closer look at.
In a particularly clever touch get it? These allow him to interact with the click just by tapping the top of the case, and saved him the trouble of adding traditional switches or buttons. But if even that is too much physical touching for you, then [Pangodream] has come up with a fairly robust system for controlling and interacting with the clock over the network.
This is likely not to come as much of a shock to you, but the ESP is pretty popular.
But is it a one-trick MCU? All while running at a respectable 20 frames per second. In addition, [Igor] created an online emulator and compiler which allows you to develop games using his engine right in your web browser. You can load up a selection of example programs and execute them to see what the engine is capable of, then try your hand at developing your own game before ever having to put the hardware together.
A seemingly endless supply of knowledge, wisdom, and memes; getting stuck on Reddit is not unlike looking something up on Wikipedia and somehow managing to spend the next couple hours just clicking through to new pages. Each press of the big red button delivers another slice of indispensable Internet wisdom, making it a perfect desk toy to fiddle with when you need a little extra push to get you through the day.
A bit of perfboard, a 3D printed case, and a suitably irresistible big red button pulls the whole thing together. Of course, we had to see for ourselves. The software itself appears impressive, and the README is detailed, well-structured, educational, and dare we say entertaining? There are other interesting performance tweaks as well, so be sure to check out the repo for all the details.
There seems to be no end to what the chips can do. You can also see a video of his work, below. As a testbed, [Jasper] ported his Tick Tock Timer project over to the new library. He got a sevenfold increase in draw speed, going from ms to 76 ms. How many projects have we featured with an ESP and a screen? Thanks, [Bodmer] for the good work, and [Jasper] for bringing it to our attention.In the results list, look for the next and install it.
Now you have the library installed you have to configure the IO pins where we have connected our screen. Now, copy the file for backup purposes and edit the original to place inside it this following content replacing all the previous content :. At this point, you can compile and upload the sketch to your ESP If everything went ok you should see some graphics, backgrounds and texts appearing in your TFT screen.
Otherwise please review carefully the IO pins configuration hard and soft. To solve this, go to the sketch and edit the line that sets the screen orientation. This is done in the setup function. Your email address will not be published.

I have now corrected the discription of connections sck is at pin 18 not Why have you commented out the TFT initialisation function?
That instantiates the object, it doesn't initialise the TFT. I repeat: why have you commented out the initialisation function? Also why tell the library MOSI is on 23 when it is on 19?GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

You signed in with another tab or window. Reload to refresh your session.The resolution of this TFT display is x which means it has pixels. This module works with 3. The ILI TFT display board which is shown in the circuit diagram above has 14 pins, the first 9 pins are for the display and the other 5 pins are for the touch module.
MOSI: master-out slave-in. SDI: serial data in. MISO: master-in slave-out. SDO: serial data out. The display module is supplied with 5V that comes from the Arduino board. This module has a built-in 3. To connect the Arduino to the display module, I used voltage divider for each line which means there are 5 voltage dividers. Each voltage divider consists of 2.
The second library is Adafruit graphics library which can be installed also from Arduino IDE library manager. ZIP Library … and browse for the. The same thing for the second file. The previous 2 libraries are included in the main code as shown below :. And this one shows Proteus simulation not perfect result!
Proteus simulation file download link is below, use version 8. I am trying to confirm that but wonder is you know the answer to this. The shield version works fine and must have logic level converters built in.
Thanks, Jack. Here is the backside of my ILI I think the J1 solderable link allows the ILI display to be powered from a 3.A video with everything you need to know has been published below, the circuit diagram if you need it is at the bottom of the article which ises the connections used in the video.
SD cards are incredibly cheap around the price of a normal size chocolate baryet for storing large amounts of data for use by or created by our micro-controllers they are extremely handy. Requiring only basic wiring to an SPI bus they are also very simple to hook up at use.
The video above concentrates on connecting up to an Arduino and shows you how to access the basic examples provided within the Arduino IDE. You could easily adapt this to other micro-controllers.
