CC1310PWM报错

请教大家一个问题:

我用的SDK为1.60.00.21移植PWM例程时报错，

undefined first referenced
symbol in file ——— —————-
PWM_config <whole-program> PWM_count <whole-program>

查看PWM.c中发现 

extern const PWM_Config PWM_config[];
extern const uint_least8_t PWM_count;

这两个变量呗extern修饰，请问时在哪里定义的这两个变量呢？

Alvin Chen：

PWM_Config 只能在CC1310_LAUNCHXL.c里面设置。

您好：是需要我们自己定义一个吗？您可否举个例子？

我不太懂你的意思：

PWM的定义在CC1310_LAUNCHXL.c里面已经定义好了

CC13X0_LAUNCHXL.c

您好，附件是我的SDK中的CC1310_LAUNCHXL.c文件。没有查到您发的这段定义，

ok找到了，感谢您的回答，我是把这个PWM移植到Sensor例程中。再次感谢！！！
