通过NTP协议进行校准的时钟

使用的硬件：

Wemos D1 Mini
OLED 64x128
蜂鸣器
倾斜开关

网络时钟部分类似于我之前的项目Very Simple MicroPython ESP8266 / ESP-12网络时钟。主要区别在于它通过NTP（网络时间协议）而不是使用第三方API来查询时间。

所述ntptime 是MicroPython的内置库，其可以通过简单地调用被容易地用于将ESP8266 / ESP32板更新系统时间（本地时间）ntptime.settime（） 。（请注意，取决于您的WiFi连接质量，您的NTP查询可能并不总是成功。）

您从NTP获得的时间为UTC + 0；在代码中，变量timezone_hour 可用于设置时区调整。例如，如果您的时区为UTC + 8，则设置timezone_hour = 8。该项目还使用非阻塞式Web服务器来提供闹钟设置界面（它不会阻塞循环过程以等待新的客户端连接，因此时钟时间仍然可以正常显示）。我写了一段代码，可以将任何名称的任意数量的参数解析到URL 的列表para_array中。这对于想要建立类似项目的人可能很有用。

蜂鸣器用作警报，倾斜开关可用于通过摇动来关闭警报。0.96英寸的OLED显示屏显示时钟时间和警报时间，警报状态（启用“ o”而未启用“ x”）以及服务器IP（在您的本地WiFI网络上）。如果没有人摇动倾斜开关，警报将在一分钟后自动关闭。该代码已在MicroPython固件v1.11上进行了测试。

xiaoAAAAA

有个问题啊

根据usocket文档

This method is a shorthand for certain settimeout() calls:

sock.setblocking(True) is equivalent to sock.settimeout(None)
sock.setblocking(False) is equivalent to sock.settimeout(0)

你代码里的

s.setblocking(False)
s.settimeout(1)

是有问题的
