STC89C52 water lamp music circuit

Overview

The running light music circuit based on stc89c52 is the first project to learn single chip microcomputer. I searched a lot of information on the Internet and found that most of the online music and running light only account for one, so I modified it slightly. I think the difficulty lies in how to realize the running light and music at the same time. My solution is: put a switch to switch the light, and then use the timer interrupt of changing the frequency of music to change the size of the case value in the switch to switch the light mode.

When the ADC12 of the 430 microcontroller is converting, why do garbled Chinese characters appear on the display after the conversion time is changed?
First of all, it is stated that when writing Chinese characters, all interrupts have been turned off!
