Display Instructions:
There are 3 display range:
1:XXXX->the unit is 1Hz, range is 1Hz-999Hz
2.XX.X->the unit is 0.1KHz,range is 0.1KHz-99.9KHz
3.X.X.X.->the unit is 1KHz, range is 1KHz-150KHz
e.g.:100->100Hz;54.1->54.1KHz;1.2.4.->12KHz

Setting Instructions:
1. Short press"Set" to interchange display the 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 Control:
Baud Rage: 9600pbs; Date Bit: 8; Stop Bit: 1;
1. Set the PWM frequency: "S1FXXXT": set the PWM1 frequency as XXX HZ(0001-999); "S1FXX.XT": set the PWM1 frequency as XXX KHZ(00.1-99.9); "S1FX.X.X.T": set the PWM1 frequency as 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 as XXX(001-100); "S2DXXXT": set the PWM2 duty cycle as XXX(001-100)
3.DOWN: set successful; FALL: set fail.
