/*
|
|
* 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 dbg_log macro to print out logs:
|
|
* dbg_log(DBG_INFO, "this is a log!\n");
|
|
*
|
|
* Or if you want to using the simple API, you can
|
|
* 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
