freertos移植easylogger

FreeRTOS移植Easylogger

获取EasyLogger代码以及添加至工程

1. 从github上git clone https://github.com/armink/EasyLogger

2. 将EasyLogger中的easylogger目录拷贝到工程中

3. 添加头文件和源代码至CMakeLists.txt中

   

修改elog_cfg.h

修改elog_port.c

测试

//! 在main中调用
void test(void)
{
    log_a("Hello EasyLogger!");
    log_e("Hello EasyLogger!");
    log_w("Hello EasyLogger!");
    log_i("Hello EasyLogger!");
    log_d("Hello EasyLogger!");
    log_v("Hello EasyLogger!");
}

//! 在线程中调用, 这里使用了letter shell组件；直接在线程中执行效果一样
void shell_cmd_elog(int argc, char *argv[])
{
    log_a("Hello EasyLogger!");
    log_e("Hello EasyLogger!");
    log_w("Hello EasyLogger!");
    log_i("Hello EasyLogger!");
    log_d("Hello EasyLogger!");
    log_v("Hello EasyLogger!");
}

结果
