Adding ESP32 to Arduino IDE

see [1]

• Note: Link to JSON file has changed to https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json, see [2]
• in Arduino IDE Preferences add the following URL as Additional Board Manager URLs
  https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
• in Arduino IDE Board Manager install "esp32"
• Select Board "ESP32 Dev Module"
• Delete or rename C:\Program Files (x86)\Arduino\libraries\WiFi library, as the ESP32 brings his one lib
• Set Tools->Upload Speed to 115200 baud

Reduce Logging

To hide the

DEBUG StatusLogger 

messages in the log, in file

c:\Program Files (x86)\Arduino\arduino_debug.l4j.ini

add

-DDEBUG=false

Coding

see C++ for Arduino coding

Alternative Software

Visual Studio Code

Installation

You really should use this one!
See How to Use Visual Studio Code for Arduino for a good install guide.

My current settings can be found in my GitHub reposititory.
Here (maybe old) copies:

Note "arduino.logLevel": "info" to reduce the logging output

Platform IO

Alternativly Platform IO VSCode Plugin can be used, but I decided to stick to stay compatible to Arduino IDE, see Platform IO Plugin

Debugging

Not tried so far: Creating and Debugging Arduino Programs in Visual Studio Code

HyperTerminal

HTerm is better than the one included in Arduino IDE
