The output duty cycle can fine-tune;duty cycle and frequency is not separately adjustable;adjusting the duty cycle will change the frequency.As a square wave signal generator,generates a square wave signal used for experimental development. Features: As a square wave signal generator,generates a square wave signal used for experimental development. Used to drive a stepper motor for generating a square wave drive signal. Generate adjustable pulse for MCU. Generate adjustable pulse,to control circuitry associated
