esp-idf-devcontainer

This repository is a Dev Container version of espressif/esp-idf-template that supports:

For instructions on how to integrate dev containers to existing repositories, see this section.

Espressif IDF extension is already configured in the Dev Container and can be used for configuring and building the project but flashing with the extension is not possible.

Quick Start

Setup

Before opening the Dev Container, please set up your desired configuration:

  1. Choose ESP_BOARD and ESP_IDF_VERSION on .devcontainer/devcontainer.json and .gitpod.Dockerfile.
  2. Choose ESP_BOARD on run-wokwi.sh and flash.sh
  3. If you want to use some parts in Wokwi and want to use a custom Wokwi project, update WOKWI_PROJECT_ID on run-wokwi.sh.

    Note

    If no project is specified the selected chip will be used.

  4. If you want to have debugging support with IDE, select the proper gdbpath in launch.json

After setting the repository, run the Dev Container, see instructions:

  • Gitpod: Gitpod does not require any special setup, it only requires an account which can be created with Bitbucket, GitLab or GitHub.
  • VS Code Dev Containers: See installation and the quick start sections.
  • GitHub Codespaces: The user needs to be part of the Codespaces beta or the repository must live under an organization.

Build

  • UI approach:
    • Use the build button from the extension in the status bar.
  • Terminal approach: 
    idf.py build

Flash

  • UI approach:
    • From the Command Palette (Ctrl-Shift-P or Cmd-Shift-P) run the Tasks: Run Task command and select Build & Flash.
    • From UI: Press Build & Flash on the left side of the Status Bar.
  • Terminal approach: 
    ./flash.sh
  • Use idf.py (idf.py -p PORT [-b BAUD] flash) from the host device.
  • Use Adafruit ESPTool:
    1. Open the Adafruit ESPTool flashing tool.
    2. Choose the desired baudrate.
    3. Connect to the serial port of the ESP board.
    4. Upload the generated binary.
  • Any alternative flashing method from host machine.

Wokwi Simulator

Warning

ESP32-S3 is not available in Wokwi

  • UI approach:

    • From UI: Press Build & Run Wokwi Simulation on the left side of the Status Bar.
    • From the Command Palette (Ctrl-Shift-P or Cmd-Shift-P) run the Tasks: Run Test Task command
    • With Ctrl-Shift-, or Cmd-Shift-,

      Note

      This Shortcut is not available in Gitpod by default.

    • From the Command Palette (Ctrl-Shift-P or Cmd-Shift-P) run the Tasks: Run Task command and select Build & Run Wokwi Simulation.

  • Terminal approach:

    bash wokwi/run-wokwi.sh

Warning

The simulation will pause if the browser tab is in the background.This may affect the execution, specially when debuging.

Debuging with Wokwi

Wokwi offers debugging with GDB.

  • UI approach:
    1. Run the Wokwi Simulation
    2. Go to Run and Debug section of the IDE (Ctrl-Shift-D or Cmd-Shift-D)
    3. Start Debugging (F5)

    ** Note **

    If using another target be sure to modify gdbpath of .vscode/launch.json.

  • Terminal approach: 
    $HOME/.espressif/tools/xtensa-esp32-elf/esp-2021r2-patch3-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gdb build/app-template.elf -ex "target remote localhost:9333"

    ** Note **

    If using another target be sure to update the command, use gdbpath propierty of .vscode/launch.json as reference.

Integrating devcontainer in existing repositories

  • For Dev Container support in VS Code and GH Codespaces:
    • Copy the .devcontainer folder to your repository.
  • For Dev Container support in Gitpod:
    • Copy the .gitpod.yml and .gitpod.Dockerfile files to your repository.
  • For task and debugging integration:
