在嵌入式实现时间戳转日期的快速查找

import datetime,time
import os

time_base = datetime.date(1970,1,1)

second_fix = []

for year in range(2010, 2040):
	for month in range(1,13):
		time_set = datetime.date(year, month, 1)
		second_fix.append(int((time_set-time_base).total_seconds()))

print(second_fix)
cnt = len(second_fix)

fd = os.open("arr.c", os.O_RDWR|os.O_CREAT)

ret = os.write(fd, bytes("uint32_t arr[%d]={"%cnt,'UTF-8'))

for index in range(cnt):
	if index%12 == 0:
		ret = os.write(fd, bytes("\r",'UTF-8'))
	target_str = "0x%08X, " % second_fix[index] 
	os.write(fd, bytes(target_str,'UTF-8'))


ret = os.write(fd, bytes("\r};\r",'UTF-8'))

os.close(fd)

对了 一不小心用的python3.5的环境 2.7的朋友自己适配

以前用过一个很笨的办法、、后面换查表法了

生成的文件加工之后

#define REC_MAX 360

uint32_t month_timestamp_fix[REC_MAX]={

	}
	if(i == 10){
		APP_ERROR_CHECK(1);
	}
	return result;
}

然后附上使用方式

typedef struct{
    uint16_t year;   //direct year
    uint8_t month;
    uint8_t day;	//day begin with 1 not 0
    uint8_t hour;
    uint8_t minute;
    uint8_t second;
}clock_t;

typedef enum {
    week_mon = 0,
    week_tues,
    week_wed,
    week_thur,
    week_fri,
    week_sat,
    week_sun,
} week_t;

#define STAMP_TABLE_YEAR_START 2010

void stamp_to_clock(const timestamp_t timestamp, clock_t* p_clock_out)
{
    uint32_t start_index = get_index(timestamp, month_timestamp_fix, REC_MAX);
    timestamp_t tmp_stamp = timestamp - month_timestamp_fix[start_index];

    p_clock_out->year = start_index / 12 + STAMP_TABLE_YEAR_START;
    p_clock_out->month = start_index % 12;

    p_clock_out->second = tmp_stamp % 60;
}

void clock_to_stamp(const clock_t* p_clock_in, timestamp_t* timestamp_out)
{
	if((p_clock_in->year <= 2010)
		||(p_clock_in->year >= 2040)){

		return;
	}
    uint32_t timestamp = month_timestamp_fix[((p_clock_in->year - STAMP_TABLE_YEAR_START) * 12) + p_clock_in->month];

    timestamp += (p_clock_in->day - 1) * 86400;
    timestamp += p_clock_in->hour * 3600;
    timestamp += p_clock_in->minute * 60;
    timestamp += p_clock_in->second;
    *timestamp_out = timestamp;
}
week_t week_now_get(void)
{
    const week_t the_day_1970_1_1 = week_thur;
    uint32_t day_past_now = timestamp_now / 86400;
    week_t week_now = (week_t)((day_past_now + the_day_1970_1_1) % 7);
    return week_now;
}

为了省ROM 查表只映射了2010到2040年

import datetime
import os

time_base = datetime.date(1970,1,1)

second_fix = []

for year in range(2010, 2040):
    for month in range(1,13):
        time_set = datetime.date(year, month, 1)
        second_fix.append(int((time_set-time_base).total_seconds()))

print(second_fix)
cnt = len(second_fix)

fd = os.open("arr.c", os.O_RDWR|os.O_CREAT)

#ret = os.write(fd, bytes("uint32_t arr[%d]={"%cnt,'UTF-8'))
ret = os.write(fd, "uint32_t arr[%d]={");

for index in range(cnt):
    if index%12 == 0:
        #ret = os.write(fd, bytes("\r",'UTF-8'))
        ret = os.write(fd, "\r")
    target_str = "0x%08X, " % second_fix[index]
    #os.write(fd, bytes(target_str,'UTF-8'))
    os.write(fd, target_str)


#ret = os.write(fd, bytes("\r};\r",'UTF-8'))
ret = os.write(fd, "\r};\r")

os.close(fd)
