Description
Features: 1. Two independent PWM outputs, which can set the frequency and duty cycle respectively; 2. Wide frequency range and high precision; 3. Serial communication 4. Two independent PWM outputs, which can set the frequency and duty cycle respectively; 5. The duty ratio ranges from 0 to 100; 6. The three frequency ranges share a duty cycle, and all setting parameters are saved after power down. Parameter: 1. Working voltage: 5--30V supports micro USB 5.0V power supply; 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 around 8--30ma; 5. Output amplitude: default 5V V-pp (can be changed by external power supply); 6. Ambient temperature: -30~+70C. Parameter Settings: The frequency is divided into three ranges: 1. XXX (no decimal point): the small unit is 1 Hz, and the value ranges from 1 Hz to 999 Hz. 2. XX.X (decimal point is ten): small unit is 0.1Khz; value range is 0.1KHz~99.9KHz 3. X.X.X. (three digits have a decimal point): small unit is 1Khz; value range 1KHz~150KHz Frequency display: (example) 100 denotes a pulse of PWM output of 100 Hz; 54.1 indicates that the PWM outputs a pulse of 54.1 kHz; 1.2.4. Indicates PWM output 124KHz pulse The module has three buttons: Set, Up, Down; 1. By short pressing the [Set] key, the display of four parameter values (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: PWM2 frequency; dU2: PWM2 duty cycle) there will be corresponding parameters before switching Name flashing prompt. 2. Press [Up] and [Down] directly to modify the current parameter value (long press can be added quickly or quickly). 3. The two PWMs are pre-configured with three kinds of frequency values. In the frequency display interface, the long-pressing [SET] key is used to switch, and the duty ratios of the three frequencies are the same. (XXX: range 1Hz~999Hz; XX.X: range 0.1Khz~99.9Khz; X.X.X.: range 1Khz~150Khz,). 1, set the frequency of the PWM "S1FXXXT": Set the frequency of PWM1 to XXX HZ (001~999) "S1FXX.XT": Set the frequency of PWM1 to XX.X KHZ (00.1~99.9) "S1F:X.X.X.T": Set the frequency of PWM1 to XXX KHZ (0.0.1.~1.5.0.) 'S1': PWM1 'S2': PWM2 'F': frequency 'D': duty cycle 'T' is the end marker 2, set the duty cycle of the PWM "S1DXXXT": Set the duty ratio of PWM1 to XXX; (001~100) "S2DXXXT": Set the duty cycle of PWM2 to XXX; (001~100) Set the success to return: DOWN; Setting failed to return: FALL. Serial Port Control: Communication standard: 9600 bps Data bits: 8 Stop position: 1 Check digit: none Flow control: none Application: 1. Used as a square wave signal generator to generate a square wave signal for experimental development; 2. Used to generate a square wave signal that drives the stepper motor driver; 3. Generate adjustable pulses for use by the MCU; 4. Generate adjustable pulses and control related circuits (applications such as PWM dimming speed regulation). Package Included: 1 x Wave Signal Generator Stepper Motor Driver
