Hello World Example

Starts a FreeRTOS task to print "Hello World".

(See the README.md file in the upper level 'examples' directory for more information about examples.)

How to use example

Follow detailed instructions provided specifically for this example.

Select the instructions depending on Espressif chip installed on your development board:

Example folder contents

The project hello_world contains one source file in C language hello_world_main.c. The file is located in folder main.

ESP-IDF projects are built using CMake. The project build configuration is contained in CMakeLists.txt files that provide set of directives and instructions describing the project's source files and targets (executable, library, or both).

Below is short explanation of remaining files in the project folder.

├── CMakeLists.txt
├── example_test.py            Python script used for automated example testing
├── main
│   ├── CMakeLists.txt
│   ├── component.mk           Component make file
│   └── hello_world_main.c
├── Makefile                   Makefile used by legacy GNU Make
└── README.md                  This is the file you are currently reading

For more information on structure and contents of ESP-IDF projects, please refer to Section Build System of the ESP-IDF Programming Guide.

Troubleshooting

  • Program upload failure

    • Hardware connection is not correct: run idf.py -p PORT monitor, and reboot your board to see if there are any output logs.
    • The baud rate for downloading is too high: lower your baud rate in the menuconfig menu, and try again.

Technical support and feedback

Please use the following feedback channels:

  • For technical queries, go to the esp32.com forum
