Electronic wooden fish

As a microcontroller enthusiast, I often encounter compilation errors, so I've decided to contribute to the microcontroller community through simple typing.
The solution uses an SG90 servo motor and an STC8H1K08 microcontroller, featuring automatic and manual modes, a menu function, real-time fine-tuning of the servo motor's angle, and EEPROM power-off memory .
A short press of the rotary encoder switches between manual and automatic modes, while a long press enters the menu. The first step adjusts the automatic timer, the second adjusts the angle value on the left side of the servo motor, and the third adjusts the angle value on the right side. The data can be adjusted by turning the knob left and right, and a long press exits the automatic mode. The automatic timer range is 0-99 seconds. The servo motor angle range is 0-200 degrees.
 
The code is written in 51C language and includes a system adjustment menu—it's quite fun.
