1、 Module Description


3-channel PWM output, wide frequency range, and independent real-time adjustment of duty cycle;


The frequency is divided into four ranges and automatically switches:


1. XXX (without decimal point): The minimum unit is 1HZ, with a value range of 1Hz~999Hz;


The minimum unit of X.XX (decimal point in hundreds) is 0.01kHz, with a value range of 1.00Khz~9.99kHz;


3.XX. X (decimal point to ten): The minimum unit is 0.1Khz; Value range 10.0KHz~99.9KHZ


4. X.X.X (decimal point in tens and hundreds): The minimum unit is 1kHz; Value range: 100KHZ~150KHz



e. G. Frequency display:


100 represents PWM output of 100Hz pulses;


1.01 represents PWM output of 1.01K pulses;


54.1 represents PWM output of 54.1K pulses with a ratio of z;


1.2.4 represents PWM output of 124KHz pulses;


The range of duty cycle values is from 0 to 100%, where 100% is represented by A0%.


All setting parameters are saved in case of power failure.



2、 Parameter settings


The module has 8 independent buttons for setting frequency and duty cycle, supporting short press (increase or decrease by one unit) and long press (quickly increase or decrease). It is very simple, and the parameters are automatically saved after setting, and will not be lost in case of power failure.



3、 Scope of application:


1. Used as a square wave signal generator to generate square wave signals for experimental development:


2. Used to generate square wave signals for controlling motor drivers;


3. Generate adjustable pulses for use by MCU;


4. Generate adjustable pulses to control related circuits (such as PWM dimming and speed regulation applications).



4、 Serial port control (single-chip TTL level communication)


Communication standard: 9600 bps Data bits: 8


Stop position: 1


Checkpoint: 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


"DX:yyy"; Set the duty cycle of PWM to x: (1-3) P \ M number, yyy: (000-100) duty cycle%; For example, at D1:050, set the duty cycle of the first PWM to 50%



3. Read the setting parameters


Send a 'read' string to read the set parameters.


Here is a special note: reading data returns can be formatted and stored in power-off mode.


Sending Change_Sead returns Read dataformat is one/two, which changes the data format returned by reading the data.

Setting successful returns: DOWN;

Setting failed and returned: FALL。
