Brief description of function:

1, normal charging (charging power supply and battery are normally connected), the LED lights normal scrolling display, full of LED lights always on.

2、Remove the battery during the charging process (the charging power supply is still connected normally), the LED light will flash for 1S.

3, the charging process will be charging power out (battery is still normally connected), the LED lights stop scrolling display, only display the current battery power, 10S stop displaying, and the microcontroller into a sleep state.

4、During the hibernation process, connect the charging power supply, then the microcontroller is awakened and starts normal charging.

5、During the hibernation process, take the battery out and put it back in, the microcontroller detects that if there is no charging power supply, it will display the current battery level, stop displaying after 10S and go into hibernation.
