编译时间

这里的编译时间指的是烧录文件的编译时间，它由编译环境的日期和时间共同决定。

设计目标

1、获取编译时间，默认是ASC码格式
2、将编译时间转换为HEX

程序修改

typedef struct
{
    uint16_t year;
    uint8_t  month;
    uint8_t  day;
    
    uint8_t  hour;
    uint8_t  minute;
    uint8_t  second;
}compile_time_st;

compile_time_st st_compile_time = {0,};


//调用以下函数时，将结构体st_compile_time的地址丢在入口参数上
void bsp_get_compile_time(compile_time_st * time_buf)
{
    const uint8_t   Month_Table[12][3] = {"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"};
    uint8_t i;
    const uint8_t   date[12] = __DATE__, 
                    time[9] = __TIME__;
    //日期 ASC-->HEX
    time_buf -> year    = (date[7]-'0')*1000 + (date[8]-'0')*100 + (date[9]-'0')*10 + (date[10]-'0')*1;
    for (i = 0;i <12;i ++)
    {
        if ((Month_Table[i][0] == date[0]) && (Month_Table[i][1] == date[1]) && (Month_Table[i][2] == date[2])){
            time_buf -> month = i + 1;
            break;
        }
    }
    //时间 ASC-->HEX
    time_buf -> day     = (date[4] == ' ') ? ((date[5]-'0')*1):((date[4]-'0')*10 + (date[5]-'0')*1);
    time_buf -> hour    = (time[0]-'0')*10 + (time[1]-'0')*1;
    time_buf -> minute  = (time[3]-'0')*10 + (time[4]-'0')*1;
    time_buf -> second  = (time[6]-'0')*10 + (time[7]-'0')*1;
}
