Parameter settings
The module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit)
and long press (fast increase or decrease), very simple, set the parameters automatically save, power failure Lost.
Module parameters
1. Working voltage:3.3 ~ 30V;
2. Frequency range:1Hz ~ 150KHz;
3. Frequency accuracy:the accuracy in each range is about 2%;
4. Signal load capacity:the output current can be about 5 ~ 30ma;
5. Output amplitude:PWM amplitude equal to the supply voltage;
6. Ambient temperature:-20 ~ +70 →.
Scope of application
1. Used as a square wave signal generator, generate square wave signal for experimental development and use;
2. Used to generate a square wave signal that controls the motor driver;
3. generate adjustable pulse for MCU use;
4. Generate adjustable pulse, control related circuit (PWM dimming speed and other applications)
Serial Port Control
Communication standards:9600 bps data bits:8
Stop bit:1
Check digit:none
Flow control:none
1. set frequency of PWM
F101:set frequency to 101HZ (001 to 999)
F1.05:set frequency to 1.05KHZ (1.00 to 9.99)
F10.5:set frequency to 10.5KHZ (10.0 to 99.9)
F1.0.5:set frequency to 105KHZ (1.0.0 to 1.5.0)
2. set PWM duty cycle
DXXX:set PWM duty cycle to XXX:(001 to 100)
Such as D050, set PWM duty cycle is 50%
3.read the set parameters
Send a inchreadinch string to read the set parameters.
Setup successfully return:Down;
Setup failed to return:FALL.
