Environment Configuration
Online installation requires the use of VPN software, while offline installation does not require the use of VPN software
Running the Program
- In the Resources section download the demo package, then unzip it and enter the
4.26inch_e-Paper_Gdirectory to see the following contents:
- Open the demo:
4.26inch_e-Paper_G\ESP32\ESP32.inoor4.26inch_e-Paper_G\ESP32\ESP32-S3.ino
- In the Arduino IDE toolbar (Tools), select the corresponding Board and Port:
- If using a core like the ESP32-S3 with PSRAM, please enable PSRAM
- Finally, click Upload. A successful upload is shown below (Arduino 2.2.1):
