Display Description:
There are 3 display range:
1: XXXX-> Unit 1Hz, range 1Hz-999Hz
2.XX.X-> unit 0.1KHz, range 0.1KHz-99.9KHz
3.XXX-> unit 1KHz, range 1KHz-150KHz,
For example: 100-> 100Hz; 54.1-> 54.1KHz; 1.2.4 .-> 12KHz

Setting Description:
1. Short press "Set" key to switch to display 4 values ??(FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: PWM2 frequency; dU2: PWM2 duty cycle)
2. Press "Up" and "Down" to set the current value

Serial port control:
Baud rate: 9600pbs; Date bit: 8; Stop bit: 1;
1. Set the PWM frequency: "S1FXXXT": set the PWM1 frequency to XXXHZ (0001-999); "S1FXX.XT": set the PWM1 frequency to XXXKHZ (00.1-99.9); "S1FX.XXT": set the PWM1 frequency to XXX KHZ (0.0.1.-1.5.0.) (S1-> PWM1; s2-> PWM2; F-> frequency; D-> duty cycle; T-> stop bit)
2. Set the PWM duty cycle: "S1DXXXT": Set the PWM1 duty cycle XXX (001-100); "S2DXXXT": Set the duty cycle of PWM2 to XXX (001-100)
3.DOWN: set successfully; FALL: setting failed.
