PWM output, you can set the frequency, duty cycle;
Frequency is divided into four ranges, automatic switching:
1>. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
2>. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
3>. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
4>. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz
5> . e.g. frequency display:
100 indicates PWM output 100Hz 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;
6> . Duty cycle range: 0 ~ 100%;
7> . All set parameters, power-down automatically saved.
1>. LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;
2>. Wide frequency range, high precision;
3>. Serial communication, TTL level
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.
1>. Working voltage: 3.3 ~ 30V;
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 about 5 ~ 30ma;
5>. Output amplitude: PWM amplitude equal to the supply voltage;
6>. Ambient temperature: -20 ~ +70 ?.
1>. Used as a square wave signal generator, generate square wave signal for experimental development and use;
2>. Used to generate a square wave signal that controls the motor driver;
3>. generate adjustable pulse for MCU use;
4>. generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
5>. serial control (single-chip TTL level communication)
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.
Set successfully return: DOWN;
Setup failed to return: FALL.
