Arduino IDE is simple!
There are many development platforms for ESP32 (ESP-WROOM-32). In some situations, using Linux or cygwin in Windows are quite intimidating for beginners. Using Arduino IDE is a more user-friendly approach.
Step 1: Add the Board URL to Arduino IDE
Open Arduino IDE (I am using version 1.8.0).An installation tutorial for Arduino IDE can be found here.Navigate to File > Preferences and click the circled button as shown below: as pic1
Enter the following URL in the new pop-up window.
You should see this progress window: as pic2
After the input is completed, click OK.
Step 2: Update the Board List
After adding the mainboard URL of ESP32 (ESP-WROOM-32) to Arduino IDE, we need to update the board list, and use Arduino IDE to download ESP32 (ESP-WROOM-32) libraries.
Open Tools->Development board->Development board manager, as shown below:pic1
After opening the development board manager, the board list will automatically be updated, as can be seen below:pic2
Step 3: Install ESP32 (ESP-WROOM-32)
After completing the update, you should find FireFly-ESP32 Mainboard options which you can then edit.
Select “ESP32 (ESP-WROOM-32)” and click “Install”. The manager will automatically download the relevant libraries. as pic2,3
Step 4: Compiling a Blink Program
Now that our compilation environment is set up, we can upload a test program.
Open tools->development board，select Firefly-ESP32 mainboard, as shown in the following:
Navigate to Tools > Board and Select Firefly-ESP32 from the list.
Please Note: If you haven’t installed ESP32 (ESP-WROOM-32) mainboard you will not see the board in the list, so be sure you follow the steps above to install it first.
Open File->Example->Basics->Blink, as shown in the following:
Click the right button to start compiling.
