Parameter Settings:
The module features 4 independent buttons for adjusting the frequency value and the duty cycle value.
Supports short press (increase or decrease by one unit) and long press (rapid increase or decrease).
All set parameters will be stored upon power-off to ensure data retention.

Frequency Display Instructions:
The frequency is divided into 4 ranges and switches automatically.
1. XXX (no decimal point): the minimum unit is 1Hz, range is 1Hz~999Hz.
2. X.XX (decimal point in the same place): minimum unit is 0.01kHz, range is 1.00kHz~9.99kHz.
3. XX.X (decimal point in the decimal place): minimum unit is 0.1kHz; range is 10.0kHz~99.9kHz.
4. X.X.X (full decimal point): minimum unit is 1kHz; range is 1kHz~150kHz
e.g. Frequency 100 represents 100Hz; display 1.01 represents 1.01kHz;
display 54.1 represents 54.1kHz; display 1.2.4 represents 124kHz
