*
* You should have received a copy of the GNU Lesser General Public License
* along with this library; if not, write to the Free Software Foundation,
* Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
*
* This library is really just two files: 'tinyprintf.h' and 'tinyprintf.c'.
*
* They provide a simple and small (+400 loc) printf functionality to be used
* in embedded systems.
*
* I've found them so useful in debugging that I do not bother with a debugger
* at all.
*
* They are distributed in source form, so to use them, just compile them into
* your project.
*
* Two printf variants are provided: printf and the 'sprintf' family of
* functions ('snprintf', 'sprintf', 'vsnprintf', 'vsprintf').
*
* The formats supported by this implementation are: 'c' 'd' 'i' 'o' 'p' 'u'
* 's' 'x' 'X'.
*
* Zero padding, field width, and precision are also supported.
*
* If the library is compiled with 'PRINTF_SUPPORT_LONG' defined, then the
* long specifier is also supported. Note that this will pull in some long
* math routines (pun intended!) and thus make your executable noticeably
* longer. Likewise with 'PRINTF_LONG_LONG_SUPPORT' for the long long
* specifier, and with 'PRINTF_SIZE_T_SUPPORT' for the size_t specifier.
*
* The memory footprint of course depends on the target CPU, compiler and
* compiler options, but a rough guesstimate (based on a H8S target) is about
* 1.4 kB for code and some twenty 'int's and 'char's, say 60 bytes of stack
* space. Not too bad. Your mileage may vary. By hacking the source code you
* can get rid of some hundred bytes, I'm sure, but personally I feel the
* balance of functionality and flexibility versus code size is close to
* optimal for many embedded systems.
*
* To use the printf, you need to supply your own character output function,
* something like :
*
* void putc ( void* p, char c) { while (!SERIAL_PORT_EMPTY) ;
* SERIAL_PORT_TX_REGISTER = c; }
*
* Before you can call printf, you need to initialize it to use your character
* output function with something like:
*
* init_printf(NULL,putc);
*
* Notice the 'NULL' in 'init_printf' and the parameter 'void* p' in 'putc',
* the NULL (or any pointer) you pass into the 'init_printf' will eventually
* be passed to your 'putc' routine. This allows you to pass some storage
* space (or anything really) to the character output function, if necessary.
* This is not often needed but it was implemented like that because it made
* implementing the sprintf function so neat (look at the source code).
*
* The code is re-entrant, except for the 'init_printf' function, so it is
* safe to call it from interrupts too, although this may result in mixed
* output. If you rely on re-entrancy, take care that your 'putc' function is
* re-entrant!
*
* The printf and sprintf functions are actually macros that translate to
* 'tfp_printf' and 'tfp_sprintf' when 'TINYPRINTF_OVERRIDE_LIBC' is set
* (default). Setting it to 0 makes it possible to use them along with
* 'stdio.h' printf's in a single source file. When 'TINYPRINTF_OVERRIDE_LIBC'
* is set, please note that printf/sprintf are not function-like macros, so if
* you have variables or struct members with these names, things will explode
* in your face. Without variadic macros this is the best we can do to wrap
* these function. If it is a problem, just give up the macros and use the
* functions directly, or rename them.
*
* It is also possible to avoid defining tfp_printf and/or tfp_sprintf by
* clearing 'TINYPRINTF_DEFINE_TFP_PRINTF' and/or
* 'TINYPRINTF_DEFINE_TFP_SPRINTF' to 0. This allows for example to export
* only tfp_format, which is at the core of all the other functions.
*
* For further details see source code.

/**
* @brief Logging library
*
* Log library has two ways of managing log verbosity: compile time, set via
* menuconfig
*
* At compile time, filtering is done using CONFIG_LOG_DEFAULT_LEVEL macro, set via
* menuconfig. All logging statments for levels higher than CONFIG_LOG_DEFAULT_LEVEL
* will be removed by the preprocessor.
*
*
* How to use this library:
*
* In each C file which uses logging functionality, define TAG variable like this:
*
* static const char *TAG = "MODULE_NAME";
*
* then use one of logging macros to produce output, e.g:
*
* LOGW(TAG, "Interrupt error %d", error);
*
* Several macros are available for different verbosity levels:
*
* LOGE - error
* LOGW - warning
* LOGI - info
* LOGD - debug
* LOGV - verbose
*
* To override default verbosity level at file or component scope, define LOG_LEVEL macro.
* At file scope, define it before including esp_log.h, e.g.:
*
* #define LOG_LEVEL LOG_VERBOSE
* #include "dxx_log.h"
*
* At component scope, define it in component makefile:
*
* CFLAGS += -D LOG_LEVEL=LOG_DEBUG
*
*
