This post talks about how you can add the Heltec ESP32 library to the Arduino IDE and use it to test your Heltec ESP32.<\/p>\n\n\n\n\n\n\n\n

Adding board support for the Heltec ESP32<\/h2>\n\n\n\n

Before adding the Heltec ESP32 library to the Arduino IDE you should ensure the Heltec ESP32 series boards are added to the Arduino IDE.<\/p>\n\n\n\n

I talked about this in my earlier blogpost so if you haven’t done that follow those instructions<\/a>. This provides the binary files that you will need to compile for these development boards.<\/p>\n\n\n\n

Added the Heltec Library<\/h2>\n\n\n\n

To use the full features of the Heltec development boards you can add the Heltec library. To do this you can go to the main menu, then select Tools ->Manage Libraries.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This loads the Library Manager and the Heltec library can be installed by searching the Heltec ESP32.<\/p>\n\n\n\n

Testing the library<\/h2>\n\n\n\n

To test the library you can load up the WiFi_LoRa_32FactoryTest example which has been added by the library. To do this go to the menu and go to the following.<\/p>\n\n\n\n

File -> Examples -> Examples from Custom Libraries -> Heltec ESP32 Dev-Boards -> Factory_Test -> WiFi_LoRa_32FactoryTest<\/p>\n\n\n\n

Once this sketch has been loaded you should be able to select the COM port of the ESP32 board and then upload it.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The test will initialize various components and then send LoRa messages when you press the button. The screen is also used to display the work that is being done.<\/p>\n\n\n\n

Further examples can be found under the Heltec ESP32 Dev-Boards menu which can demonstrate how to use the board.<\/p>\n","protected":false},"excerpt":{"rendered":"
