[Hangshun Training Camp] Based on Hangshun HK32F030M network clock

This is the second time. The last time I drew the board by myself, I still used AD. At that time, I drew all the packages and schematics by myself. I originally wanted to practice, but now I feel it is unnecessary. It is super convenient to call the schematics and packages here at Lichuang. Before painting, I looked at the group chat, and it turns out that many big guys have done a lot of interesting and targeted things in it. I'm not very familiar with it personally, so let's make it simple first, and then I'll make something better than this next time.

It still feels good when laying out, but not when wiring. The ground wire makes me feel that this board will not be that good. I have not studied hardware before, but I have been exposed to software, so there should be a lot of room for improvement.

The esp8266 on the board can be debugged independently, because I led out its serial port and needed to communicate with the hkf030 and then connect it back, and finally completed the functions I needed. There is a network clock, a watchdog reset is added, and the four blue lights can be used as night lights. I like this night light very much. I don’t need to buy a night light. The brightness is just right. You can also adjust the light switch according to the time. . The code is also shared here. The esp8266 is connected to wifi separately, so there is no entry in the code. The knowledge in the code describes how to get the time. ESP8266 uses AT instructions. ~~~~

Thank you again to Jialichuang for this opportunity!
