QuickStart

Software Framework Configuration

Support IDE	Version
[ESP-IDF]	[V5.1/5.2/5.3]
[Arduino IDE]	[esp32 >=v3.1.0]
[Platformio IDE]

ESP-IDF Framework (Novice tutorial)

• Supported Versions: v5.1/5.2/5.3
• Download the example code from the repository and compile/run it directly.
• Repository Address: examples

Arduino Framework (Novice tutorial)

1. InstallArduino,Choose installation based on your system type.

2. Install the ESP32 core: Search for and download esp32(by Espressif >= v3.1.0) in the Board Manager.

3. Install the required libraries:

   • Search and install ESP32_Display_Panel (v1.0.3). Select Yes for automatic dependency installation.
   • Install the LVGL (v8.4.0) library.

4. Open the example: ESP32_Display_Panel-> examples -> arduino -> gui -> lvgl_v8.

5. Configure the esp_panel_board_supported_conf.h file:

   • 打开该文件的宏: #define ESP_PANEL_BOARD_DEFAULT_USE_SUPPORTED (0)——> #define ESP_PANEL_BOARD_DEFAULT_USE_SUPPORTED (1)
   • Search development board #define BOARD_VIEWE_UEDX24240013_MD50E，And first comment to make it work. Note that do not turn on multiple development boards.

6. Configure tool options :

   ESP32-C3

   Setting	Value
   Board	ESP32C3 Dev Module
   CPU Frequency	160MHz (WiFi)
   Core Debug Level	None
   USB CDC On Boot	Disabled
   Erase All Flash Before Sketch Upload	Disabled
   Flash Frequency	80MHz
   Flash Mode	QIO
   Flash Size	4MB (32Mb)
   JTAG Adapter	Disabled
   Partition Scheme	Huge APP
   Upload Speed	921600

7. Select the correct port.

8. Click "√" in the upper right corner to compile,If the compilation is correct, connect the microcontroller to the computer,Click "→" in the upper right corner to download.

9. If the color is abnormal after burning, please open the lv_conf.hfile in the example and modify the configuration:#define LV_COLOR_16_SWAP 0——>#define LV_COLOR_16_SWAP 1

firmware download

Firmware	Description	Picture
ESP-IDF	Original

1. Open the project file "tools" and locate the ESP32 burning tool. Open it.

2. Select the correct burning chip and burning method, then click "OK." As shown in the picture, follow steps 1->2->3->4->5 to burn the program. If the burning is not successful, press and hold the "BOOT-0" button and then download and burn again.

3. Burn the file in the root directory of the project file "firmware" file,There is a description of the firmware file version inside, just choose the appropriate version to download.

FAQ

• Q. After reading the above tutorials, I still don't know how to build a programming environment. What should I do?
• A. If you still don't understand how to build an environment after reading the above tutorials, you can refer to the VIEWE-FAQ document instructions to build it.

• Q. Why does Arduino IDE prompt me to update library files when I open it? Should I update them or not?
• A. Choose not to update library files. Different versions of library files may not be mutually compatible, so it is not recommended to update library files.

• Q. Why is there no serial data output on the "Uart" interface on my board? Is it defective and unusable?
• A. The default project configuration uses the USB interface as Uart0 serial output for debugging purposes. The "Uart" interface is connected to Uart0, so it won't output any data without configuration.
  For PlatformIO users, please open the project file "platformio.ini" and modify the option under "build_flags = xxx" from "-D ARDUINO_USB_CDC_ON_BOOT=true" to "-D ARDUINO_USB_CDC_ON_BOOT=false" to enable external "Uart" interface.
  For Arduino users, open the "Tools" menu and select "USB CDC On Boot: Disabled" to enable the external "Uart" interface.

• Q. Why is my board continuously failing to download the program?
• A. Please hold down the "BOOT" button and try downloading the program again.
