  • [SOLVED] print float with RTT viewer

    I try to print 'float' number using RTT Viewer.
    But I know that SEGGER_RTT_printf only accept 'int'

    So what's the solution to print the float numbers?

    Thank you

  • Hi,


    SEGGER_RTT_printf() is a minimal implementation of printf() and only supports the most basic format modifiers.
    If advanced functionality is required, use sprintf() into a buffer and output it via SEGGER_RTT_WriteString().
