Macro Definition Documentation

NAMEDVALUE

#define NAMEDVALUE

(

x

)

F(DEBUG_STR(x) " = ") << x

Macro for printing an expression as a string, followed by its value.

The expression string is saved in PROGMEM using the F(...) macro.

Examples

Debug.ino.

Definition at line 69 of file Debug.hpp.

DEBUG

#define DEBUG

(

x

)

Value:

do {                                                                       \
        DEBUG_OUT << x << DEBUG_ENDL;                                          \
    } while (0)

Print an expression to the debug output if debugging is enabled.

Examples

Debug.ino.

Definition at line 75 of file Debug.hpp.

DEBUGREF

#define DEBUGREF

(

x

)

Value:

do {                                                                       \
        DEBUG_OUT << F(DEBUG_LOCATION) << x << DEBUG_ENDL;                     \
    } while (0)

Print an expression and its location (file and line number) to the debug output if debugging is enabled.

The location is saved in PROGMEM using the F(...) macro.

Examples

Debug.ino.

Definition at line 84 of file Debug.hpp.

DEBUGFN

#define DEBUGFN

(

x

)

Value:

do {                                                                       \
        DEBUG_OUT << DEBUG_FUNC_LOCATION << x << DEBUG_ENDL;                   \
    } while (0)

Print an expression and its function (function name and line number) to the debug output if debugging is enabled.

The function name is saved in RAM.

Examples

Debug.ino.

Definition at line 93 of file Debug.hpp.

DEBUGTIME

#define DEBUGTIME

(

x

)

Value:

do {                                                                       \
        unsigned long t = millis();                                            \
        unsigned long h = t / (60UL * 60 * 1000);                              \
        unsigned long m = (t / (60UL * 1000)) % 60;                            \
        unsigned long s = (t / (1000UL)) % 60;                                 \
        unsigned long ms = t % 1000;                                           \
        const char *ms_zeros = ms > 99 ? "" : (ms > 9 ? "0" : "00");           \
        DEBUG_OUT << '[' << h << ':' << m << ':' << s << '.' << ms_zeros << ms \
                  << "]:\t" << x << DEBUG_ENDL;                                \
    } while (0)

Print an expression and the time since startup to the debug output if debugging is enabled.

Format: [hours:minutes:seconds.milliseconds]

Examples

Debug.ino.

Definition at line 104 of file Debug.hpp.

DEBUGVAL

#define DEBUGVAL

(

...

)

DEBUGVALN(COUNT(__VA_ARGS__))(__VA_ARGS__)

Print multiple expressions and their values to the debug output if debugging is enabled.

For example, DEBUGVAL(1 + 1, digitalRead(2)) could print 1 + 1 = 2, digitalRead(2) = 0. A maximum of 10 expressions is supported. The expression strings are saved in PROGMEM using the F(...) macro.
