4. 角度: %.3f(三位小数) 5. 状态: INP(or MAXL or MAXR) EOPE(operation error) LIMI(over limit)
6. 角度帧头: $ 帧尾 '\r'
7. 状态帧头: # 帧尾 '\r'

C99 Error

The timespec comes from POSIX, so you have to 'enable' POSIX definitions:

#if __STDC_VERSION__ >= 199901L  
#define _XOPEN_SOURCE 600  
#else  
#define _XOPEN_SOURCE 500  
#endif /* __STDC_VERSION__ */  

#include <time.h>
int main()
{
    struct timespec asdf;
    return 0;
}

For the warning: implicit declaration of function 'usleep':

gcc -std=gnu99

motor-client

the client for control the server
