嵌入式HAL移植EasyLogger日志系统

添加头文件、源文件

然后编译处理报错

static const char *color_output_info[] = {
        [ELOG_LVL_ASSERT]  = ELOG_COLOR_ASSERT,
        [ELOG_LVL_ERROR]   = ELOG_COLOR_ERROR,
        [ELOG_LVL_WARN]    = ELOG_COLOR_WARN,
        [ELOG_LVL_INFO]    = ELOG_COLOR_INFO,
        [ELOG_LVL_DEBUG]   = ELOG_COLOR_DEBUG,
        [ELOG_LVL_VERBOSE] = ELOG_COLOR_VERBOSE,
};将上面语句替换成c99之前的标准实现

解决部分类型转换：

添加输出端

在elog_port.c添加如下return避免死机
