1: How to Set Up Development Tools With Arduino IDE 1.x

1.1: Installing Arduino IDE 1.x

1.2: Installing Arduino core for the ESP32

1.3: Configuring Arduino core for the ESP32

1.4: Installing the MWings Library

This guide provides the steps to set up tools for TWELITE SPOT firmware development.

1 - How to Set Up Development Tools With Arduino IDE 1.x

Instructions for setting up a development tools with Arduino IDE 1.x

This guide explains the procedure for setting up a development tools with Arduino IDE 1.x.

Although you can upload sketches using the latest Arduino IDE 2.x just like with Arduino IDE 1.x, as of May 2023, Java-based plugins such as arduino-esp32fs-plugin and EspExceptionDecoder do not work, so the Legacy IDE (1.x) is recommended.

1.1 - Installing Arduino IDE 1.x

How to install the integrated development environment (IDE)

This guide explains the installation procedure for Arduino IDE 1.x.

If you have already installed Arduino IDE 1.x, you can ignore this article.

Download

Open the Arduino official download page in your web browser and download the Legacy IDE (1.8.X).

For example, the Windows installer is “Windows Win 7 and newer”.

Installation

Run the downloaded file and follow the instructions to install Arduino IDE 1.x.

1.2 - Installing Arduino core for the ESP32

How to install the toolchain for ESP32

This guide explains how to install the compiler and libraries dedicated to the ESP32 for Arduino.

If you have already installed the Arduino core for the ESP32, you can ignore this article.

For detailed installation instructions, please refer to the official documentation (in English).

Adding Board Information

Launch Arduino IDE 1.x and open File -> Preferences from the toolbar.

Enter the following URL into the Additional Board Manager URLs field and click OK.

https://espressif.github.io/arduino-esp32/package_esp32_index.json

Installation

Open Tools -> Board: “Arduino Uno” -> Board Manager from the toolbar.

The selected board may not be “Arduino Uno”, but please proceed with the same steps.

Type “ESP32” in the search box and install the esp32 board definitions.

Operation has been confirmed with version 2.0.5 or later.

1.3 - Configuring Arduino core for the ESP32

How to configure the toolchain for ESP32

This guide explains how to configure the Arduino core for the ESP32 required for TWELITE SPOT firmware development.

From here on, the content is specific to TWELITE SPOT.

Selecting the Board Type

From the toolbar, select Tools → Board → ESP32 Arduino → ESP32 Dev Module.

Board Settings

Please configure as shown in the image below.

By default, the Flash size is set to 4MB (32Mb).

Please change this to 16MB (128Mb).

1.4 - Installing the MWings Library

How to install the MWings library for using TWELITE

This guide explains the installation procedure for the MWings library used with TWELITE.

Installation

Open Sketch -> Include Library -> Manage Libraries…

Type MWings in the search box and install MWings.
