 *
 * In your C/C++ file, enable/disable DEBUG_ENABLE macro, and then include this
 * header file.
 *
 * #define DBG_TAG           "MOD_TAG"
 * #define DBG_LVL           DBG_INFO
 * #include <rtdbg.h>          // must after of DBG_LVL, DBG_TAG or 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!");
