Hancheng Zhao：
已自行解决，方法Options / C/C++Compiler preprocessor / Defined symbols 中输入
ewarm
PART_TM4C123GH6PM
TARGET_IS_TM4C123_RB1
UART_BUFFERED
确认即可
xyz549040622：
回复 Hancheng Zhao:
这个宏定义没有的话，好多外设是找不到的。换个芯片的话，定义也要改变的。
Hancheng Zhao：
回复 xyz549040622:
如果换芯片我要改哪些宏定义呢，能否用tiva系列的其他芯片帮我举个例子谢谢
xyz549040622：
回复 Hancheng Zhao:
TM4C123GH6PM ，根据你对应的芯片，修改这个就可以
Hancheng Zhao：
回复 xyz549040622:
TARGET_IS_TM4C123_RB1
里面的RB1又表示什么呢，因为看到头文件里面有if define *_RA1什么的。。。谢谢
xyz549040622：
回复 Hancheng Zhao:
这个应该是主管ROM之类的函数的吧，我具体看看再给你回复。
Hancheng Zhao：
回复 xyz549040622:
哦哦，原来是版本差异啊
