Module Description
PWM output, you can set the frequency and duty cycle separately;
Common mode:
Frequency range 1HZ~150KHZ Duty cycle 000~100%, duty cycle step 1%
Fine mode:
Frequency range 1HZ~15KHZ Duty cycle 00.0~100%, duty cycle step 0.1%.
Frequency is divided into four ranges with automatic switching:
1.XXX (no decimal point): the smallest unit is 1Hz, value range 1Hz~999Hz;
2.X.XX (decimal point in hundredths): the smallest unit is 0.01Khz, value range 1.00Khz~9.99Khz;
3.XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range 10.0Khz~99.9Khz
4.X.X.X (decimal point in tenth and hundredth place): the smallest unit is 1Khz; the value range is 1KHz~150KHz.
e.g. Frequency Display:
100 means PWM outputs 100Hz pulse;
1.01 means PWM outputs 1.01K pulse;
54.1 means PWM outputs 54.1KHz pulse;
1.2.4 means PWM outputs 124KHz pulse;
Duty cycle value range: 0~100%;
All setting parameters, power-down save.
