笔者在这个任务里卡了好久好久，笔者的ntptime这个库的例程在本次任务的W5500-PICO -evb 板子上无法使用，MPY文档里都是在8266等WiFi芯片里使用，W5500-PICO会显示没有对应的库。。。

用查询方法查找固件，也会发现没有对应的这个库文件

help('modules')

后来在看到其他大佬的帖子后才发现，W5500evb有专用的烧录固件，同理,使用PICO链接W5500模块也可刷这个库来实现NTP功能

传送门：MicroPython - Python for microcontrollers

烧录好新固件之后再试试：

这个MPY的官方固件就包含NTPTIME这个链接NTP的专用库了

使用HELP函数可以查看NTPTIME中的各类函数定义和结构：

import ntptime

help(ntptime)
help(ntptime.settime)
help(ntptime.utime)

运行后会看到PICO当前固件里的对应函数的各种功能，这个小技巧对于开发MPY还是蛮好用的

2.从NTP服务器获取时间并显示

从上文已知NTPTIME库中的HOST常量已经设置为pool.ntp.org,我们只需使用ntptime.settime()这个函数获取NTP服务器返回的时间数据即可。

在@StreakingJerry大佬的帖子启发下，还需要手动增加对应的秒数来确保校准成功。

在已经配好网络的情况下添加驱动和时间校准代码：

烧录到板卡中：

补充内容 (2024-2-24 02:09): 后续使用延时同时做出了电压检测和每分钟刷新的效果，参考文章https://bbs.eeworld.com.cn/thread-1272400-1-1.html

ntptime这个库应该不是基础库吧，看看例程里是不是有，放到文件夹里再import应该就可以了
