Functions
int	rc_servo_init (void)
	Configures the PRU to send servo pulses. More...
void	rc_servo_cleanup (void)
	Cleans up servo functionality and turns off the power rail. More...
int	rc_servo_power_rail_en (int en)
	enables or disables the 6V power rail to drive servos. More...
int	rc_servo_set_esc_range (int min, int max)
	Sets the pulse width range used by the rc_servo_esc_send_pulse_normalized() function. More...
int	rc_servo_send_pulse_us (int ch, int us)
	Sends a single pulse of desired width in microseconds to one or all channels. More...
int	rc_servo_send_pulse_normalized (int ch, double input)
	Like rc_send_pulse_us but translates a desired servo position from -1.5 to 1.5 to a corresponding pulse width from 600 to 2400us. More...
int	rc_servo_send_esc_pulse_normalized (int ch, double input)
	Like rc_send_pulse_normalized but translates a desired esc throttle position from 0 to 1.0 to a corresponding pulse width from 1000 to 2000us. More...
int	rc_servo_send_oneshot_pulse_normalized (int ch, double input)
	Like rc_send_pulse_normalized but translates a desired esc throttle position from 0 to 1.0 to a corresponding pulse width from 125 to 250us. More...
