-
Download Arduino IDE from official site and install into your system. We have use Arduino IDE 1.8.19
-
Once installation done will add ESP32-Wroom-32 board support into IDE, for this first you need to add below link into preference:
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.jsonSelect File > Preference, and add link as show in below image,
-
Now will install ESP32 based boards as shown in below image,
-
Once done, keeping default settings select the ESP32 Dev Module with suitable com port (may be different in your case) as shown below,
-
In case you don't see com port then you will have to install CP2102 driver from Link. Download and install as per your operating system.
-
check below one recommended for windows user
-
Once installed correctly, it will look like the image below.
-
-
Download library zip file provided here in github.
-
Extract and copy files inside Document > Arduino > Libraries folder. Make sure to restart Arduino IDE whenever you update or add any libraries.
-
At this step you are all set to test codes, for easy getting started we have provided various demo example codes in github which you can download and try.
-
Open one example code in Arduino and make sure you have selected correct board ( ESP32 Dev Module) with suitable com port, click on upload button to transfer code on ESPi.
-
Checkout other examples below and build your own custom program codes using those references.
To compile and run Ethernet server codes without getting compile Error , You will have to replace default "Server.h" file comes when ESP32 board installed in Arduino, location is shown below
C:\Users\YourUserName\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.9\cores\esp32
Replace with file "Server.h" provided here in github.
The examples folder in repository includes ready to use and experimental code with ESPi, some listed below ->
- Example 1 : Display demo code
- Example 2 : WiFi Webserver application demo
- Example 3 : Combine test of EthernetWebServer and WiFiWebServer on ESPi board
- Example 4 : Application demo code to connect ESPi board with ThingSpeak cloud server using onboard ethernet facility
Play with it and create your own, Happy Coding!
