int setPPM(int channel, float frequency, float offset,
float duty, char invert, int bind_offset, int bind_duty);
Sets up a PPM output on the selected digital output channel with the specified
frequency and duty cycle. The PPM output of the PPM can be inverted. The offset and
duty of the PPM can be bound to a PWM/PPM on another channel on the same RIO
block so that they share an edge.

starts with the output low, goes high at the offset, and stays high
for the remainder of the duty cycle; inverted will start with the out-
put high, goes low at the offset, and stays low for the duration of
the duty cycle.
