Macro Definition Documentation¶

define FLT_FMT¶

#define FLT_FMT (
    _n
) `STRINGIZE ( PPCAT ( PPCAT (%c%d.%0, _n), d))`

Floating point output formatting string. Include in your printf-style format string example: printf("float value = " FLT_FMT(3) " continue like that", FLT_VAR(3, x));

define FLT_FMT3¶

#define FLT_FMT3 `FLT_FMT (3)`

Shorthand for 10^-3 fraction, output equivalent to %.3f

define FLT_VAR¶

#define FLT_VAR (
    _n,
    _x
) `/* multi line expression */`

Floating point output variable preprocessing Note: uses truncation instead of rounding -> the last digit may be off

define FLT_VAR3¶

#define FLT_VAR3 (
    _x
) `FLT_VAR (3, _x)`

Shorthand for 10^-3 fraction

define LOGGER_BUFFER¶

#define LOGGER_BUFFER `128`

size in bytes

define LOGGER_NEWLINE¶

#define LOGGER_NEWLINE `"\r\n"`

Logger configuration custom newline character sequence

define PPCAT¶

#define PPCAT (
    A,
    B
) `PPCAT_NX (A, B)`

concatenate tokens

define PPCAT_NX¶

#define PPCAT_NX (
    A,
    B
) `A##B`

Helper macros for string concatenation and macro expansion non-expanding concatenation

define STRINGIZE¶

#define STRINGIZE (
    A
) `STRINGIZE_NX (A)`

make a string

define STRINGIZE_NX¶

#define STRINGIZE_NX (
    A
) `#A`

non-expanding stringize
