### Tools & Debug Probes

Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions.

#### On-Board Debug Tools

Boards listed below have on-board debug probe and ARE READY for debugging! You do not need to use/buy external debug probe.

    [env:latest_stable]
    platform = titiva
    board = ...

    ; Custom stable version
    [env:custom_stable]
    platform = titiva@x.y.z
    board = ...

### Upstream

    [env:upstream_develop]
    platform = https://github.com/platformio/platform-titiva.git
    board = ...
