[HAO]Signal generator PWM pulse frequency duty cycle adjustable module LCDDescription:
100% Brand new and high quality
Size: 5.2*3.2cm
Color: Black,Blue
Package include: 1 x PWM Pulse Frequency Adjustable Module
Module Highlights:
-LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;
-Wide frequency range, high precision;
-Serial communication, TTL level
First, the module description
PWM output, you can set the frequency, duty cycle;
Frequency is divided into four ranges, automatic switching:
-XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
-X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
-XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
-X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz
Frequency display: 100 indicates PWM output 100Hz pulse;
1.01 indicates PWM output 1.01K pulse;
54.1 indicates that the PWM output has a pulse of 54.1 kHz;
1.2.4 indicates that the PWM output is 124 kHz pulse;
Duty cycle range: 0 ~ 100%;
All set parameters, power-down automatically saved.
Second, the parameter settings
The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a unit) and long press (fast increase or decrease), set the parameters automatically save, power down Not lost.
Third, the module parameters:
-Working voltage: 3.3 ~ 30V;
-Frequency range: 1Hz ~ 150KHz;
-Frequency accuracy: the accuracy in each range is about 2%;
-Signal load capacity: the output current can be about 5 ~ 30ma;
-Output amplitude: PWM amplitude equal to the supply voltage;
-Ambient temperature: -20 ~ +70 ?.
Fourth, the scope of application:
-Used as a square wave signal generator, generate square wave signal for experimental development and use;
-Used to generate a square wave signal that controls the motor driver;
-generate adjustable pulse for MCU use;
-generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
-serial control (single-chip TTL level communication)
Communication standard:
9600 bps Data bits: 8
Stop bit: 1
Check digit: none
Flow control: none
1, set the frequency of the PWM
"F101": Set the frequency to 101 HZ (001 to 999)
"F1.05": set the frequency of 1.05 KHZ (1.00 ~ 9.99)
"F10.5": Set the frequency to 10.5KHZ (10.0 ~ 99.9)
"F1.0.5": set the frequency of 105KHZ (1.0.0 ~ 1.5.0)
2, set the PWM duty cycle
"DXXX": set the PWM duty cycle to XXX; (001 ~ 100)
Such as D050, set the PWM duty cycle is 50%
3, read the set parameters
Send a "read" string to read the set parameters.
Set successfully return: DOWN;
Setup failed to return: FA
