LCD Display Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module Description: LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle; Wide frequency range, high precision; Serial communication, TTL level First, the module description PWM output, you can set the frequency, duty cycle; Frequency is divided into four ranges, automatic switching: XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz; X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz; XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz frequency display: 100 indicates PWM output 100Hz pulse; 1.01 indicates PWM output 1.01K pulse; 54.1 indicates that the PWM output has a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is 124 kHz pulse; Duty cycle range: 0 ~ 100%; All set parameters, power-down automatically saved. Second, the parameter settings The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a unit) and long press (fast increase or decrease), set the parameters automatically save, power down Not lost. Third, the module parameters: Working voltage: 3.3 ~ 30V; Frequency range: 1Hz ~ 150KHz; Frequency accuracy: the accuracy in each range is about 2%; Signal load capacity: the output current can be about 5 ~ 30ma; Output amplitude: PWM amplitude equal to the supply voltage; Ambient temperature: -20 ~ +70 . Fourth, the scope of application: Used as a square wave signal generator, generate square wave signal for experimental development and use; Used to generate a square wave signal that controls the motor driver; generate adjustable pulse for MCU use; generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications). 5, serial control (single-chip TTL level communication) Communication standard: 9600 bps Data bits: 8 Stop bit: 1 Check digit: none Flow control: none 1, 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) 2, 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% 3, read the set parameters Send a "read" string to read the set parameters.
