Constructor Detail

Freqout

public Freqout(int pin)

Creates a Freqout object based on PWM. Does not start running.

Parameters:

pin - the pin to generate the PWM signal on.

Freqout

public Freqout(int pin,
               int frequency)

Creates a Freqout object based on PWM. Does not start running.

Parameters:

pin - the pin to generate the PWM signal on.

frequency - frequency in hertz/10 (1 - 12k)

Method Detail

setFrequency

public void setFrequency(int frequency)

Set output frequency. Accurate only to 8.68us timebase.

Parameters:

frequency - frequency in hertz/10 (1 - 12k)

freqout

public void freqout(int frequency,
                    int time)

Set output frequency for a fixed amount of time. It starts and stops the base PWM.

Parameters:

frequency - frequency in hertz/10 (1 - 12k)

time - amount of time in CPU.delay() units

freqout

public void freqout(int time)

Set output frequency for a fixed amount of time. It start()s and stop()s the base PWM.

Parameters:

time - amount of time in CPU.delay() units
