Install Arduino IDE 1.8.19 on Raspberry Pi OS 32-bit buster, and setup arduino-esp32

Install Arduino IDE 1.8.19 on Raspberry Pi OS 32-bit buster


Visit https://www.arduino.cc/en/software, download Linux ARM 32 bits, and extract the downloaded file.

My usual practice rename extracted folder to arduino and move to Home Folder.

Open Terminal, switch to the arduino folder, run install.sh as su:

$ sudo ./install.sh

Setup arduino-esp32

In Arduino IDE, MENU > Preferences

Add the release link to Additional Boards Manager URLs.

Stable release link:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

or Development release link:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json

Open Boards manager, search and install "esp32 by Espressif Systems".

Done. Now you can program ESP32/C3/S2/S3 in Arduino Framework.
