/*
 * The macro definitions for debug
 *
 * These macros are defined in static. If you want to use debug macro, you can
 * use as following code:
 *
 * In your C/C++ file, enable/disable DEBUG_ENABLE macro, and then include this
 * header file.
 *
 * #define DBG_SECTION_NAME    "MOD"
 * #define DBG_ENABLE          // enable debug macro
 * #define DBG_LEVEL           DBG_INFO
 * #include <rtdbg.h>          // must after of DEBUG_ENABLE or some other options
 *
 * Then in your C/C++ file, you can use LOG_X macro to print out logs:
 * LOG_D("this is a debug log!");
 * LOG_E("this is a error log!");
 *
 * If you want to use different color for different kinds log, you can
 * #define DBG_COLOR
