When using a custom Wokwi project, please change the WOKWI_PROJECT_ID in run-wokwi.sh. If no project id is specified, a DevKit for esp32 will be used.

• Terminal approach:

  scripts/run-wokwi.sh [debug | release]
  

  If no argument is passed, release will be used as default

• UI approach:

  The default test task is already set to build the project, and it can be used in VS Code and Gitpod:

  • 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.
  • From UI: Press Build & Run Wokwi on the left side of the Status Bar.

Wokwi offers debugging with GDB.

• Terminal approach:

  $HOME/.espressif/tools/xtensa-esp32-elf/esp-2021r2-patch3-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gdb target/xtensa-esp32-espidf/debug/esp_buddy_rs -ex "target remote localhost:9333"

  2. Go to Run and Debug section of the IDE (Ctrl-Shift-D or Cmd-Shift-D)
  3. Start Debugging by pressing the Play Button or pressing F5
  4. Choose the proper user:
     • esp when using VS Code or GitHub Codespaces
