tft display esp32 factory

The component TFT supports a 2.8 inch TFT display with a resolution of 240*320 pixels.The display is not soldered on the board, but there is a 14 pin connector for a TFT display. The ILI9341 has been tested.

There are four sample projects for the Arduino IDE which could be downloaded: TFT-Box3D (download here), TFT-Graphic-Test (download here), TFT-HelloWorld (download here) and TFT-HowToUseFonts (download here). And there are two examples for the Arduino IDE for using the touch functionality which could be downloaded: TFT-TouchBtn (download here) and TFT-TouchDraw (download here).

There are two dip switches for the component: SW311 and SW314. If you want to use the TFT display all switches on SW311 have to be on on. If you additonally want to use the touchpad of the display all switch of SW314 have to be on. The following two tables shows the functions and the potential conflicts with other components

This guide is about DWIN HMI Touch Screen TFT LCD Display. HMI Means Human-Machine Interface. DWIN is specialized in making HMI Touch screen displays that are compatible with all microcontrollers like Arduino, STM32, PIC, and 8051 families of Microcontrollers.

This is a Getting Started tutorial with 7-inch DWIN HMI TFT LCD Display. We will see the architecture, features, board design, components, and specifications. We will also learn about the TTL & RS232 interfaces. Using the DGUS software you can create UI and with SD Card you can load the firmware on display memory.

One of the method to load the firmware to the T5L DWIN LCD Display is by using the SD Card. An SD Card of up to 16GB can be used to download the firmware files. We can easily insert the Micro SD card into the SD Card slot on the backside.

After copying the file, remove the SD Card from your computer and insert it into the SD Card slot of DWIN LCD Display. Then power the display using the USB Cable. The firmware downloading process will start automatically.

The next part of this tutorial includes creating UI and interfacing DWIN LCD Display with Arduino. For that you can follow the DWIN LCD Arduino Interfacing Guide.

Variables, initializers, etc.Right below #include I added the Button2 library with #include and the bootlogo with #include "bmp.h".

This is a thing of which I don"t know what it does and how it works. I just copied it from the examples of LilyGO"s TTGO T-Display repository:Then I added #define TFT_BL 4 from the TTGO T-display example sketch. This sets the pinnumber of the backlight of the ST7789V screen.

The backlight can be controlled with a PWM signal so I added an option to the menu to set the initial backlight intensity. The initial value can be set up at int ledBacklight = 80; The default of my demo sketch is 80 but you can set it to any number in the range of 0 to 255. If you set it at 0 the backlight will be off. All graphics will be send to the display but you won"t see anything on the screen. The default TFT_eSPI and ArduinoMenu examples dont"t set the backlight and the first issue I encoutered was seeing nothing on the display. The actual issue was not setting the backlight to the on state.

I"ve changed TFT_eSPI gfx; to TFT_eSPI gfx = TFT_eSPI(135, 240); to provide the TFT_eSPI library the dimensions of the screen. The screen is driven as portrait mode and so the width is the small side with 135 pixels and the height is the long side with 240 pixels. In the sketch image rotation is enabled and thus everything will be displayed in landscape mode (quarter clockwise).

Button2 btnDwn(BTN_DWN);Because PWM parameters on a ESP32 can"t be set with the analogWrite() function because of lack of support for it in the board properties we need to set the PWM frequency, resolution and channel manually. After that we need to attach a pin to a PWM channel. Later on in the script you"ll see how this works but first right after int ledCtrl=LOW; we set the values we need:

In a previous article, we’ve looked into adding visual elements to a generic TFT screen for our primary flight display. But what a waste it would be if we didn’t utilize the screen to its fullest. That is why today we will bring our flight display to the next level by adding touch support. This guide will work with screens driven by ILI9341, ILI9481, ST7789, and many more chips.

Because an Arduino struggles to drive a 4-inch LCD display I’d highly recommend using a more powerful board like the Teensy, STM32, or my favorite the ESP32. The ESP32 has that perfect balance between price, performance, and features. This will also be the board we will use for this guide. This doesn’t mean you can’t use a different board but if you do there is a chance you need to find libraries that are tailored to your specific board.

Now we know how it works it’s time to start coding. The first thing we need to do is include our libraries and create a TFT_eSPI object and a BitsAndDroidsFlight32 object. The TFT_eSPI class contains all the logic we need to display visual elements and register our touches. By creating an object we can access all these functions that belong to the class by referencing our object.

To see if our touch screen logic works we need to add some visual elements to press. If you’ve been following along with the radio display video you’re able to use those elements as a starting point. To keep things clean and tidy I will be adding 2 empty buttons to demonstrate the logic used.

Buttons with rounded corners look more appealing than sharp corners. The TFT_eSPI library has a function called tft.fillRoundRect(x starting point, y starting point, width, height, corner radius, color). We could fill in these parameters every time we want to draw a rounded square. But to keep things tidy and clean we will create a struct that holds all the data of our rounded square. We then add a function to draw these elements on our screen. For a full in-depth guide on how this works check out this article.

We could read the raw output of the screen but some debouncing and smoothening can improve your experience by a mile. Luckily the TFT_eSPI library does all the hard work for us. The function tft.getTouch(&t_x, &t_y) returns false if the touch is invalid. If the touch is valid it stores the coordinates at our t_x and t_y coordinates.

The bottom-right corner pin, labeled DBG, is attached to the ESP32-S2’s debug serial output. It isn’t useful within Tasmota but can be helpful for development, troubleshooting, or data logging.
