在代码里/** * LWIP_TCP_KEEPALIVE==1: Enable TCP_KEEPIDLE, TCP_KEEPINTVL and TCP_KEEPCNT
* options processing. Note that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set
* in seconds. (does not require sockets.c, and will affect tcp.c)
*/
#if !defined LWIP_TCP_KEEPALIVE || defined __DOXYGEN__
#define LWIP_TCP_KEEPALIVE              1
#endif
手动修改了宏定义为1,考虑到下次用cube生成代码该宏定义会还原，请问cube里面有相关设置吗？在哪里设置？谢谢啦！
