Error[Pe020]: identifier "namespace" is undefined F:\github\NUCLEOF411RE\Source\api\DigitalIn.h 23

No "namespace" defined.

The default configuration compilation language of IAR project is Auto, as shown in the figure below:

The suffix of the main file in your new project is.c, and IAR is automatically judged to be C language when compiled, so it will report an error.

Change main to.cpp suffix, IAR automatically judges C++ language when compiling, and compiles normally.

After reading the above, do you have any further understanding of what the problem is with mbed? If you still want to know more knowledge or related content, please pay attention to the industry information channel, thank you for your support.
