1. Module description

Two independent PWM outputs, the frequency and duty cycle can be set separately;

The frequency is divided into three ranges:

1. XXX (no decimal point): The minimum unit is 1Hz, and the value range is 1Hz~999Hz;

2. XX.X (the decimal point is in the tens place): the smallest unit is 0.1Khz; the value range is 0.1KHz~99.9KHz

3. X.X.X. (three digits have a decimal point): the smallest unit is 1Khz; the value range is 1KHz~150KHz

e.g. Frequency display: 100 means PWM output 100Hz pulse;

54.1 means that the PWM outputs a 54.1KHz pulse;

1.2.4. Indicates PWM output 124KHz pulse

Duty cycle value range: 0~100;

The three frequency ranges share a duty cycle, and all setting parameters are saved after power-off.
