Software Setup and Programming

Note: All of the examples in this tutorial assume you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE. If you have not previously installed an Arduino library, please check out our installation guide.

To get started with the MicroMod ESP32 Processor Board, you'll need to install the ESP32 Board Definition. Open the Arduino IDE (must be v1.8.13 or later) and navigate to File->Preferences, like so:

Arduino Preferences, under File

In the "Additional Board Manager URL" box, make sure you have the following json file included. If you do not have it, add it to your preferences.

language:c
https://raw.githubusercontent.com/sparkfun/Arduino_Boards/main/IDE_Board_Manager/package_sparkfun_index.json

If you have more than one json file, you can click on the button outlined in red and add the json link at the end. It'll look something like the following:

Once you've got your preferences updated, go to Tools -> Board and select the Boards Manager like so:

Search for "ESP32", and you should find the SparkFun ESP32 Boards board package. Make sure the latest version is selected and click Install.

Once the board definitions have been installed, you should see the SparkFun ESP32 MicroMod Board under your Tools -> Board -> SparkFun ESP32 Arduino menu.

Note: Our board definition package should install all of the tools needed to compile code for the ESP32. If you run into trouble having code compile or downloading due to tools not being found, you may need to install Espressif's Arduino ESP32 package manually.

Voila! You're ready to rock your ESP32 MicroMod Processor Board!
