    Hello all,

     

    In Arduino environment global define ESP32 or ESP8266 are define depending target choice.

    I use it with compiler #if statement to select one header or an other depending the target.

    but in esp-idf with arduino as component, global define ESP32 or ESP8266 are not create by default.

    So, my question : where do I need to declare this  global define like it is propagated when compile then use it in headers to make code selection at compile time ?

     

    Thanks

    Regards

    Hi,

    For Arduino projects please use the first page of VisualGDB Project Properties to manage preprocessor definitions and other global options.

    For ESP-IDF projects please use the VS Project Properties of a specific ESP-IDF component to define exported preprocessor macros (those macros will apply to all components in a project, not just the selected component). You can access the properties of the main component via the Properties command for the project node itself.
