程序中出现warning C206: 'Date_dispaly':missing function-prototype

Answer 1

Date_Display要么没函数要么没声明，同页面void声明，不同页extern 或者放入共用的.h文件，
void Date_Display(unsigned char display , unsigned int data);
//最好数组最好采用地址指针方式， 后面的uint8_t data部分改成uint *addr
//你time_data的声明我记得没有这种 intuchar 吧，要么int要么char int四字节，char一字节

追问

添加之后有报错，但是并不明白哪里错了？
