Description
Product Description
1.Frequency is divided into three ranges:
1)XXX (no decimal point):the smallest unit is 1Hz, the range 1Hz~999Hz;
2)XX.X (decimal point in ten):The minimum unit is 0.1Khz;the range of 0.1KHz~99.9KHz
3) X.X.X.(there are three decimal point):the smallest unit is 1Khz:the range 1KHz~150KHz
2.Frequency display example:
1)"100" indicates that the PWM output pulse of 100HZ;
2) "54.1"indicates that the PWM output pulse of 54.1KHz
3)"1.2.4." Indicates that the PWM pulse output 124KHz
Duty Cycle in the range:0 to 100;
Three frequencies duty cycle is the same,all the parameters non-volatile.
3.Highlights:
1) Two independent PWM generators can set the frequency,duty cycle;
2) The wide frequency range,high accuracy;
3) Can serial communication.
Product Parameters1)Working voltage:5--30V,support micro USB 5.0V power supply ;
2) Frequency range:1Hz~150KHz
3)The frequency accuracy:±2%
4)Output Current:< 30mA
5)Output amplitude:Default 5vp-p (settable)
6)Operating temperature range:-30~+70°.
Parameter Settings:
Module has three buttons [Set], [Up], [Down];
1): Press [Set] key to switch the display four parameters
(FR1: PWM1 frequency; du1:PWM1 duty cycle: FR2:
frequency of PWM2;dU2:PWM2 duty cucle),before
the handover parameters, there will be corresponding parameter name flash.
2)Press [Up], [Down] keys to modify the current parameter value(long press can quickly add or subtract fast).
3)Two PWM each have three preset frequency,
the frequency display interface, long press [SET] key to switch between three types of frequencies,three kinds of frequency duty cycle is the same value.(XXX:range 1Hz~999Hz;XX.X: range 0.1Khz;X.X.X.:range 1Khz~150Khz,).
Serial Control
Baud rate:9600 bps.
Data bits:8.
Stop bits:1.
Parity bit:none.
Flow control:none.
1,set the PWM frequency.
"S1FXXXT":setting PWM1 frequency of XXX HZ(001~ 999).
"SIFXX.XT":set the frequency of PWM1 XX.X KHZ(00.1 ~99.9)
"S1F:X.X.X.T":setting PWM1 frequency of XXX KHZ(0.0.1~1.5.0.).
'S1':PWM1
'S2':PWM2
'F' : Frequency
'D' :Duty Cycle.
'T'is the end flag.
Set the PWM duty cycle
"S1DXXXT" : setting PWM1 duty cycle XXX ; ( 001~100).
"S2DXXXT" : set PWM2 duty cycle XXX;(001~100).
Setting successful return:DOWN;
Setting failback:FALL.
Scope Of ApplicationAs square wave signal generator which generates a square wave signal;
to provide a signal to the stepping motor driver;
Adjustable pulse generation for chip use;
produce variable pulse signal, the control-related circuit ( PWM dimming,speed).
