ESP32 - Software Installation

To program for ESP32 board, we need:

A text editor to write the code (human-readable code)
A compiler to compile the code (human-readable code) to the binary code (ESP32-understandable code)
A programmer to upload the binary code to ESP32

It seems to be complicated ⇒ don't worry, The Arduino IDE does all for you. you just need to:

Install this Arduino IDE
Write the ESP32 code (human-readable code)
Click a button on the Arduino IDE to compile and upload the code to ESP32 board.

Arduino IDE is available for Windows, Mac OS X and Linux. We need to do the following steps:

Download the Arduino IDE via this link and install it.
After installing Arduino IDE, we can use it to program for Arduino immidiately. However, in order to program for ESP32, we need to do some environment configuration on Arduino IDE
Open Arduino IDE
Go to File Preferences on Arduino IDE

https://dl.espressif.com/dl/package_esp32_index.json

Paste the coppied text into the Additional Board Manager URLs field as shown in the figure below. Then, click the OK button

※ NOTE THAT:

Note: In case you use the ESP8266 and ESP32, you can separate the URLs with a comma as follows:

https://dl.espressif.com/dl/package_esp32_index.json, http://arduino.esp8266.com/stable/package_esp8266com_index.json

Open the Boards Manager by clicking on the Board Manager icon on the left navigation bar of Arduino IDE
Type “ESP32”, then click Install button for the “ESP32 by Espressif Systems“

The software installation is done. The next step is to run first program on ESP32 board: ESP32 - Hello World program.
