配置串口引脚函数GPIOPinConfigure(uint32_t ui32PinConfig);

编译就出现，请问一下怎么解决

user\chuankou.c(16): error:  #20: identifier "GPIO_PC4_U7Rx" is undefined
user\chuankou.c(17): error:  #20: identifier "GPIO_PC5_U7Tx" is undefined

    确认源码中包含了头文件：#include "driverlib/pin_map.h"

    增加器件型号定义，例如在CCS中：

    工程属性~Build~ARM Compiler~Advanced Options~Predefined Symbols

    增加PART_TM4C1230D5PM（和你的芯片信号对应上，这里是TM4C1230D5PM）
