For information about the capabilities of the formatters, see Formatters for printf and Formatters for scanf.

Printf formatter

If you select Auto, the linker automatically chooses the appropriate formatter for printf-related functions based on information from the compiler.

To override the default formatter for all printf-related functions, except for wprintf variants, choose between:

  • Printf formatters in the IAR DLIB Library—Full, Large, Small, and Tiny

Choose a formatter that suits the requirements of your application.

Select Enable multibyte support to make the printf formatter support multibytes.

Scanf formatter

If you select Auto, the linker automatically chooses the appropriate formatter for scanf-related functions based on information from the compiler.

To override the default formatter for all scanf-related functions, except for wscanf variants, choose between:

  • Scanf formatters in the IAR DLIB Library—Full, Large, and Small

Choose a formatter that suits the requirements of your application.

Select Enable multibyte support to make the scanf formatter support multibytes.

Buffered terminal output

Buffers terminal output during program execution, instead of instantly printing each new character to the C-SPY Terminal I/O window. This option is useful when you use debugger systems that have slow communication.
