ESP32-S3 Parallel 4.0" TFT with Touch
introduction
ESP32-S3 Parallel 4.0 TFT with Touch is a new solution for IoT application, Choose the ESP32-S3, whicn is a execllent performance controllter. Compare with ESP32-S3 4.3 inch IPS display it increase the I2S output. In many IoT scenarios, Audio playing can have a better exhibition effect. by integrating display/ touch/ audio speaker/ Lipo charger, to make this product ideal for applications such as IoT controlling, electronic photo frame, etc.

Usage
If you need backlight control, you need to solder R28 whose resistance is 1kΩ(the default is not soldered when leaving the factory), and remove the R29 resistor.
Note that the same version of the libraries and packages are recommended in case of updates make unexpected results. All the projects are based on ESP32-S3. If you didn't install the ESP32 Board SDK, you can follow this tutorial to install it.
Install the "TAMC_GT911" in the Arduino IDE.
Click “Tools> Manager Libraries” to search for and install the 1.0.2 version of TAMC_GT911 library.
Select and set the parameter in the Tools menu before uploading the sketch，shows as below:
Note: Different PC has different Serial COM number, select your local serial number
LVGL Demo
The version of the libraries shows as below. It may cause compilation errors if you use different version of the libraries!
1.Download the MF_Lvgl library.
2.Open the sketch>include library> ADD.ZIP library
3.Choose the path of MF_Lvgl and unzip the library.
4.Open the GitHub, click the >>ESP32-S3-Parallel-TFT-with-Touch-4inch/example/LvglWidgets/
5.Download the SD_file and unzip it, copy these files to the microSD card.
6.Verify and upload the sketch.
PDQgraphics demo
You can get the screen performance with PDQgraphics demo. Install the GFX_Library_for_Arduino library.
-
Open the GitHub and click >>example>> PDQgraphicstest.
-
Verify and upload the code. it will display as follows.
If you want to know more display effects with ESP32-S3 Parallel 4.0 TFT with Touch, watch the following video.
Bightness control Demo
Notice: Before you can implement this demo, you must solder R28 whose resistance is 1kΩ(the default is not soldered when leaving the factory), and remove the R29 resistor.
Open Bightness control Demo by Arduino.
Use Type-C USB cable to connect the board and PC, note plug the cable to USB-NATIVE interface, and select the development board "ESP32S3 Dev Module" and the port.
Verify and upload the code. it will display as follows.
Swipe the progress bar and you will see the brightness of the screen change and you can open the Serial Monitor to capture the coordinates of the screen points.

-
Q1: Why the display fails to respond sometimes I touch?
-
A1: The touching interface is loose, please reconnect it.
Q2: I get the error "no matching function for call to 'Arduino_ESP32RGBPanel::Arduino_ESP32RGBPanel(int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int, int)'); ^" when I compile the code, how to solve it?
A2: Mabe you use the newest ArduinoGFX v1.4.7 not the tested v1.3.1. The oringinal code need to make some changes to support v1.4.7 as below:
