INIT_1pulse

switches the prescaler to divisor 1 (highest frequency)

INIT_2pulse

switches the prescaler to divisor 8

INIT_3pulse

switches the prescaler to divisor 64

INIT_4pulse

switches the prescaler to divisor 256

INIT_5pulse

switches the prescaler to divisor 1024 (lowest frequency)

Timernumber

0 -5 = choise timer 0-5

DONEpulse

Spits a pulse when done

To use the node in your project you should have the gst/pwm-prescaler-set library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
