Parameter Settings:
1. Module has three buttons: [Set], [Up], [Down].
2. Press [Set] key to switch the display of four parameters (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: frequency of PWM2; dU2: PWM2 duty cycle), before the handover parameters, there will be corresponding parameter name flashing.
3. Press [Up], [Down] keys to modify the current parameter value (long press can quickly add or subtract fast).
4. Two PWM each have three preset frequency, and in the frequency display interface, long press [SET] key to switch between three types of frequencies, three kinds of frequency duty cycle is the same. (XXX: range 1Hz ~ 999Hz; XX.X: range 0.1Khz ~ 99.9Khz; X.X.X .: range 1Khz ~ 150Khz,).
