Getting started with VSCode & ESP-IDF & ESP32

Installation

1. At VSCode, add the following extensions:

• C/C++
• C/C++ Extension Pack
• CMake
• CMake Tools

2. At GitHub:

• Make a fork from https://github.com/liukiti/ESP32 to your personal github account;

3. At terminal:

• Install the following packages:

  $ sudo apt-get install git wget flex bison gperf python3 python3-pip python3-setuptool cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0​
  

• Clone the repository ESP32 from your account

  • Change the USUARIO to your github user

    $ git clone git@github.com:USUARIO/ESP32.git
    

• init submodule esp-idf @ 7eaeaaa

  $ cd ESP32
  $ git submodule update --init --recursive
  

• Install the ESP-IDF

  $ cd esp-idf
  $ ./install.sh esp32
  

Your Code

• Put your code inside the ESP32/myCodes directory;
• It's recommended to use an IDF example as a template. Copy one from ESP32/esp-idf/examples/

Open

• double click in edit.desktop;
• at VSCode, click on No Kit Selected at the bottom menu (blue bar);
• Select GCC 8.4.0 xtensa-esp32-elf .. at the dropdown menu;
• Open a new terminal in VSCode;
• Navigate to the project directory, like ESP32/myCodes/blink;
• Execute the following command to build the application:

  $ idf.py all
  

• If the previous step was successed, try to flash and monitor the device at /dev/ttyUSB0 serial port

  $ idf.py flash monitor -p /dev/ttyUSB0
  

useful commands

• At terminal, view if ESP-IDF is configured and ready to go

$ echo $IDF_PATH

• Check port on Linux

ls /dev/tty*

Adding user to dialout on Linux

• The currently logged user should have read and write access the serial port over USB.

sudo usermod -a -G dialout $USER

• Make sure you re-login to enable read and write permissions for the serial port

Change ESP-IDF commit/tag

$ cd ESP32/esp-idf

$ git fetch origin
$ git checkout <commit_id>

$ git submodule update --init --recursive
$ git ./install.sh esp32
