Heltec ESP32+LoRa Series Quick Start

简体中文

Before all operation, please confirm whether the USB driver, Git and Arduino IDE has been installed correctly. If not, please refer to this two articles establish serial connection and Install Git and Arduino IDE.

There are two methods to install the development framework, choose one of they:

• Via Arduino Board Manager

• Via Git

 

Via Arduino Board Manager

Step1. Download Arduino-ESP32 Support

Open Arduino IDE, and click File->Peferences.

 

Input the last ESP32 package URL: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/releases/download/0.0.5/package_heltec_esp32_index.json

Click Tools --> Board --> Boards Manager..., search Heltec ESP32 in the new pop-up dialog, then click install

The source code of Heltec ESP series (ESP32 & ESP8266) framework available here: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series

Step2. Download the Heltec ESP32 Library

Open Arduino IDE, then Select Sketch->Include Library->Manage Libraries... Search Heltec ESP32 and install it.

The source code of Heltec ESP32 library available here: https://github.com/HelTecAutomation/Heltec_ESP32

 

Via Git

• For Windows: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/InstallGuide/windows.md

• For MacOS: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/InstallGuide/mac.md

• For Linux

  • Debian/Ubuntu: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/InstallGuide/debian_ubuntu.md

  • Fedora: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/InstallGuide/fedora.md

  • OpenSUSE: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/InstallGuide/opensuse.md

 

Example

This section for verifying whether you can program with Arduino or not. Now, The USB cable connects to Heltec ESP32 board, then select your serial port which is connected to Heltec ESP32 board.

Select a demo example, compile and upload.

Execute an example

Correctly select a board and relevant options in the Tools menu:

Then select an example likes XXXXXX_FactoryTest.ino

Compile & Upload

New a Heltec ESP32 program

Open Arduino IDE, create a new .ino file, then copy the below code.

#include <heltec.h>

// the setup routine runs once when starts up
void setup(){

  // Initialize the Heltec ESP32 object
  Heltec.begin(true /*DisplayEnable Enable*/, true /*LoRa Disable*/, true /*Serial Enable*/, true /*PABOOST Enable*/, 470E6 /**/);
}

// the loop routine runs over and over again forever
void loop() {

}

compile it and upload, the screen (if this board has a screen) will show and Arduino’s serial monitor will print something, it

Heltec ESP32 Based Dev-baords Develop Environment

We suggest you confirm whether the USB driver, Git and Arduino IDE has installed first. If not, please view this two articles establish serial connection and Install Git and Arduino IDE.

CONTENT

1. Setting Environment
   • Step1. Download Heltec Arduino-ESP32 Support
   • Step2. Download the Heltec ESP32 Library
2. Example

1. Setting Environment

(Only two steps to complete setting)

Step1. Download Arduino-ESP32 Support

Open Arduino IDE, and click File->Peferences->Settings

Input last esp32 board manager URL

Now the last board manager URL: https://docs.heltec.cn/download/package_heltec_esp32_index.json

Click Tools->Board:->Boards Manager..., search Heltec ESP32 in the new pop-up dialog, then click install

The source code of Heltec ESP series (ESP32 & ESP8266) framework available here: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series

Step2. Download the Heltec ESP32 Library

Open Arduino IDE, then Select Sketch->Include Library->Manage Libraries... Search Heltec ESP32 and install it

The source code of Heltec ESP32 library available here: https://github.com/HelTecAutomation/Heltec_ESP32

Example

This section for verifying whether you can program with Arduino or not. Now, The USB cable connects to Heltec ESP32 board, then select your serial port which is connected to Heltec ESP32 board.

Select a demo example, compile and upload

1. Execute a example likes FactoryTest.ino

Correct select the board you had connected to computer and the specified serial port: e.g. WiFi Kit 32, WiFi LoRa 32, COM3(my PC is COM3)

Then select an example likes XXXXXX_FactoryTest.ino

Upload it

2. New a Heltec ESP32 program

Open Arduino IDE, then new a .ino file, then copy the below code.

#include <heltec.h>

// the setup routine runs once when starts up
void setup(){

  // Initialize the Heltec ESP32 object
  Heltec.begin(true /*DisplayEnable Enable*/, true /*LoRa Disable*/, true /*Serial Enable*/, true /*PABOOST Enable*/, 470E6 /**/);
}

// the loop routine runs over and over again forever
void loop() {

}

compile it and upload, the on board screen (if have) will show and Arduino’s serial monitor will print something, it means Heltec ESP32 board is running successfully!

Enjoy!
