关于nsp430固件库使用问题

我在使用MSP430F5xx_6xx的driverlib时  在调用#include "timer_a.c"时会报错，错误如下：

Error[Pe020]: identifier "OFS_TAxCTL" is undefined F:\driverlib\MSP430F5xx_6xx\timer_a.c 79
Error[Pe020]: identifier "OFS_TAxCTL" is undefined F:\driverlib\MSP430F5xx_6xx\timer_a.c 183
。。。。。。。。

此类错误有十几个，把#include "timer_a.c“屏蔽  就ok了，请问大家是什么问题？源程序如下

哪位大哥指点一下？我问TI代理的技术支持，他没用过

看看你的头文件，OFS_TAxCTL有没有定义，或者程序里最后x有没有被替换成数字。

另外有时候头文件总变来变去的，很是烦人，而且变来变去也不一定没错误。

不如把timer_a.c贴出来看看
