  • debug_printf and _printf with RTT

    What is the difference between using the technique described in the SES manual for using the debug_* functions and including the Segger RTT files shipped with EMBOS that seem to implement the regular printf?

    Thanks,

    Kenny

  • Hi,

    The DebugIO functions (e.g. debug_printf) use the configurable library functions in Embedded Studio for I/O.
    The library configuration can be Breakpoint (Semihosting), DCC or Memory Poll.

    The RTT file override printf directly to print via RTT,
    which is faster and does not affect the target system.

    It is recommended to use RTT instead of other I/O mechanisms on all Cortex-M devices.
