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-EPD47 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

7️⃣ FAQ

1. Which one does the sleep current measurement example use? ?

   Sleep current test measured by demo example

2. How to fix afterimages?

   Please upload examples/screen_repair to try to remove afterimages. It is not 100% able to remove afterimages.

3. 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(IO0) button , While still pressing the BOOT(IO0) button, press RST
   3. Release the RST
