idf.py add-dependency "espressif/extended_vfs=*"

Examples

Please use the component manager command create-project-from-example to create the project from example template

idf.py create-project-from-example "espressif/extended_vfs=*:gpio_simple"

Then the example gpio_simple will be downloaded in current folder, you can check into it for build and flash.

Or you can download examples from esp-iot-solution repository:

1. gpio_simple
2. i2c_bh1750
3. i2c_tt21100
4. ledc_simple
5. spi_master_simple
6. spi_slave_simple

Q&A

Q1. I encountered the following problems when using the package manager

Executing action: create-project-from-example
CMakeLists.txt not found in project directory /home/username

A1. This is because an older version packege manager was used, please run pip install -U idf-component-manager in ESP-IDF environment to update.
