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 LilyGO AMOLED Series 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 Install from Arduino Library Manager (recommended)

1. Install Arduino IDE

7️⃣ 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. 1.47 inches AMOLED(T-Display-AMOLED-Lite) does not support hardware screen rotation function

4. If you use external power supply instead of USBC, please turn off the CDC option. This is because the board will wait for USB access when it starts.

   • For Arduino IDE users, it can be turned off in the options , Please note that turning off USB CDC will turn off Serial redirection to USBC. At this time, you will not see any Serial message output when opening the port from USBC, but output from GPIO43 and GPIO44.

   Tools -> USB CDC On Boot -> Disable

   • For Platformio users, you can add the following compilation flags in the ini file

   build_flags =
       ; Enable -DARDUINO_USB_CDC_ON_BOOT will start printing and wait for terminal access during startup
       ; -DARDUINO_USB_CDC_ON_BOOT=1
   
       ; Enable -UARDUINO_USB_CDC_ON_BOOT will turn off printing and will not block when using the battery
       -UARDUINO_USB_CDC_ON_BOOT
