XY-LPWM Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display Module

XY-LPWM Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display Module is a two-channel PWM signal generator. It has dedicated switches for adjusting the frequency and duty cycle separately. Using this module PWM output, frequency and duty cycle can be set as per requirements.

Communication Standard:

1. 9600 bps Data bits: 8
2. Stop bit: 1
3. Check digit: none
4. Flow control: none
5. 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)
6. 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%
7. Read the set parameters Send a "read" string to read the set parameters. Set successfully return: DOWN; Setup failed to return: FALL.

Application:

1. This is used to drive a stepper motor driver’s square wave.
2. Generate an adjustable pulse for MCU.
3. Generate an adjustable pulse for controlling relative circuit (PWM adjust lightspeed, etc).
4. Used as a square wave signal generator for experimental development and use.
