1、keil重选则器件
2、 移植FREERTOS出错

分析原因:空间不足
解决方案：—>device 暂时选择一个大一点的器件
3, 编译警告，assert_param未申明
warning: #223-D: function “assert_param” declared implicitly”
分析原因：STM32XXXXX_conf.h 条件编译未执行
添加该定义。
4，弹窗提示
分析原因：
1，文件路径没成功
2，文件中没什么东西，编译为空
3，文件编译选项，文件格式未识别
解决办法：
1，移除后，添加文件，并修改。
2，检查路径是否有空格，中文等可能未被识别的路径，C/C++路径中正确选择编译路径
3，右键选择文件，魔棒中选择文件个，工程魔棒中选择文本格式未C99.
