XY-PWM 1Hz~150KHz PWM Frequency Meter Signal Generator Source Frequency Duty Cycle Adjustable Module

XY-PWM 1Hz~150KHz PWM Frequency Meter Signal Generator Source Frequency Duty Cycle Adjustable Module

Description:
XY-PWM signal generator is a device that provides electrical signals at a variety of frequencies, square wave, and output levels. It is used as a signal source or excitation source for testing. Widely used in production practice and technology.

Advantages:
1. With shell. LCD displays frequency and duty cycle, PWM output can set frequency and duty cycle separately;
2. Wide frequency range and high precision;
3. Serial communication.

Module Instruction:
Frequency and duty cycle can be set separately for PWM output.

Frequency is divided into four ranges, automatically switching:
1. XXX (no decimal point): The minimum unit is 1Hz, and the value range is 1Hz~999Hz;
2. X.XX (the decimal point is in the hundreds): The minimum unit is 0.01Khz, and the range is 1.00Khz~9.99Khz;
3. XX.X (the decimal point is in the tens place): The smallest unit is 0.1Khz; the value range is 10.0KHz~99.9KHz;
4. X.X.X (the decimal point is in the tens and hundreds): The smallest unit is 1Khz; the value range is 1KHz~150KHz.

e.g. Frequency display: 100 means PWM output 100Hz pulse;
1.01 means that the PWM outputs 1.01K pulses;
54.1 means that the PWM outputs a 54.1KHz pulse;
1.2.4 means PWM output 124KHz pulse;
Duty cycle value range: 0~100%;

All setting parameters are saved when power off.

Parameter Settings:
The module has 4 independent buttons to set frequency and duty cycle. It supports short press (increase or decrease by one unit) and long press (rapid increase or decrease), which is very simple. Parameters are automatically saved after setting, and parameters are not lost when it is power-off.

Applications:
1. Used as a square wave signal generator to generate square wave signals for experimental development and use;
2. Used to generate a square wave signal for controlling the motor driver;
3. Generate adjustable pulses for MCU use;
4. Generate adjustable pulses and control related circuits (applications such as PWM dimming and speed adjustment).

Serial Port Control (MCU TTL Level Communication):
- Communication standard: 9600 bps;
- Data bits: 8
- Stop bit: 1
- Check Digit: none
- Flow control: none

1. Set the frequency of PWM:
"F101": Set the frequency to 101 HZ (001~999)
"F1.05": Set the frequency to 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 to 105KHZ (1.0.0~1.5.0)

2. Set the duty cycle of PWM:
"DXXX": Set the duty cycle of PWM to XXX; (001~100).
For example: D050, set the PWM duty cycle to 50%.

3. Read setting parameters:
Send "read" string to read the set parameters.
Set successful return: DOWN.
Setting failure and return: FALL.
