  • The code size increased after using sprintf function with the standard library.
    Is there any way to compress the size?
    • The sprintf function executes the floating point type conversion processing, which results in increase of size.
      If the floating point type conversion is not executed, add the dummy function _Ldtob() to C source as shown below to compress the code size.
      　Example)
      #include <stdio.h>
      char buf[32];
      void main(void)
      {
      sprintf(buf, "test");
      }

      void _Ldtob(void *p, char code){} // Dummy function for code size reduction
