ESP8266 RTOS SDK Error Problems

[PaulTsai111]

樂鑫您好:

我目前在編譯一個RTOS V1.4.0版SDK的Code,一直有出現一個小問題

我不知道真正問題是哪裡.能否給予一些使用上的提示或方向.

这个是C的一个基本语法问题，你做了typedef struct save_date *ptr1和typedef struct exec_date *ptr2，typedef是一个类型定义的关键字，你做了typedef以后， ptr1就相当于是 struct save data*,他是一个类型名称，而你调用Add函数时，传递的是一个类型名称，这就完全不对了，就相当于，你调用add(int,float),你应该用类型名称定义变量，然后在调用函数时传递变量名

我把碼改成這樣,仍會出現以下錯誤,我還是搞不懂這個問題點是?

我晕啊！！！
你应该这么写：

Code: Select all

#include "esp_common.h"
char *s1_year = "2016";
char *s1_mon = "06";
char *s1_day = "17";
char *s1_hour = "10";
char *s1_min = "18";
char *s1_sec = "30";

char *s2_year = "2016";
char *s2_mon = "06";
char *s2_day = "17";
char *s2_hour = "12";
char *s2_min= "00";
char *s2_sec= "00";

int total_save_sec;
int total_exec_sec;
struct date1{
   int save_sec;
   int save_min;
   int save_hour;
   int save_day;
   int save_mon;
   int save_year;   
};
struct date2{
   int exec_sec;
   int exec_min;
   int exec_hour;
   int exec_day;
   int exec_mon;
   int exec_year;
};
struct date1 save_date;
struct date2 exec_date;
struct date1* ptr1 = &save_date;
struct date2* ptr2 = &exec_date;


void set_value(struct date1 *ptr1,struct date2 *ptr2)
{
  //save_date.save_year = 
  //ptr1->save_year=atoi(s1_year);
  //exec_date.exec_year = 
//  ptr2->exec_year=atoi(s2_year);

    ptr1->save_year=5;
   ptr2->exec_year=10;
}
void user_init(void){

   printf("SDK version:%s\n", system_get_sdk_version());
   printf("user_init running ...\n");
   wifi_set_opmode(NULL_MODE);
   set_value(ptr1,ptr2);
   //Add(s1_year,s2_year);
