3️⃣ PlatformIO Quick Start (Recommended)

1. Install Visual Studio Code and Python
2. Search for the PlatformIO plugin in the VisualStudioCode extension and install it.
3. After the installation is complete, you need to restart VisualStudioCode
4. After restarting VisualStudioCode, select File in the upper left corner of VisualStudioCode -> Open Folder -> select the T-Display-S3-Long directory
5. Wait for the installation of third-party dependent libraries to complete
6. Click on the platformio.ini file, and in the platformio column
7. Uncomment one of the lines src_dir = xxxx to make sure only one line works
8. Click the (✔) symbol in the lower left corner to compile
9. Connect the board to the computer USB
10. Click (→) to upload firmware
11. Click (plug symbol) to monitor serial output
12. If it cannot be written, or the USB device keeps flashing, please check the FAQ below

4️⃣ Arduino IDE Quick Start

• It is recommended to use platformio without cumbersome steps

1. Install Arduino IDE
2. Download or clone project T-Display-S3-Long
3. Copy all the files in T-Display-S3-Long/lib and paste them into Arduion library folder(e.g. C:\Users\YourName\Documents\Arduino\libraries).
4. Open Arduino IDE, select the examples\xxx example of project T-Display-S3-Long throught "File->Open".
5. Configuration of board is as follows:

6. Select Port
7. Click upload , Wait for compilation and writing to complete
8. If it cannot be written, or the USB device keeps flashing, please check the FAQ below

6️⃣ FAQ

1. The board uses USB as the JTAG upload port. When printing serial port information on USB_CDC_ON_BOOT configuration needs to be turned on. If the port cannot be found when uploading the program or the USB has been used for other functions, the port does not appear. Please enter the upload mode manually.

   1. Connect the board via the USB cable
   2. Press and hold the BOOT button , While still pressing the BOOT button, press RST
   3. Release the RST
   4. Release the BOOT button
   5. Upload sketch

2. If the above is invalid, burn the binary file to check whether the hardware is normal

3. The OTG external power supply function requires turning on the PMU OTG enablement ,If the USB input is connected and the OTG is set to output, the battery will not be charged.

         PMU.enableOTG();  //Enable OTG Power output
         PMU.disableOTG(); //Disable OTG Power output

4. Turning the physical switch to OFF will completely disconnect the battery from the motherboard. When charging is required, turn the switch to ON.

5. When the battery is not connected and the USB is plugged in, the board's LED status indicator light will flash. You can use PMU.disableStatLed(); to turn off the indicator light, but this means that if the battery is connected for charging, the LED light will also be disabled. If you need to enable the charging status indicator, please call PMU.enableStatLed();

7️⃣ Depends on required libraries

Do not upgrade the LVGL version, the lvgl software rotation has been forced to open.

• lvgl 8.3.0
• XPowersLib
