BCD binary clock

Overview

1. Introduction
The clock chip uses RX8025, and the main control chip is stc8G1k08A (refer to the big guy’s plan: clock based on TM1650 - Jialichuang EDA open source hardware platform (oshwhub.com))
, which displays hours, minutes and seconds in bcd code, where Four LEDs are used to display the ones digit, and 3 LEDs are used for the tens digit (there will be a light in the tens digit of the hour display that is not used, but it is added for the sake of symmetry). The

buttons on the back are used to control the LEDs to turn off or on.

Note: The first time use needs to be in the program. Perform time calibration in (directly uncomment the code that writes the time, fill in the time, and re-comment it after successful burning)
