VF EXPORT_SYM void disable_servo

VF EXPORT_SYM int get_servo_enabled

VF EXPORT_SYM int get_servo_position

(

int

servo

)

Parameters

servo

The port of the servo

Returns

The servo's position as a 10 bit integer (which is an integer between 0 and 1024)

Note

Thie method will return the last sent position, not the currently set position.

For example, imagine the following:

1. set_servo_position(0, 700);
2. ... Some time passes ...
3. set_servo_position(0, 300);
4. get_servo_position(0);

get_servo_position(int) will return 700 rather than 300, because 300 hasn't been sent to the servo yet.

VF EXPORT_SYM void set_servo_enabled	(	int	port,
		int	enabled
	)

VF EXPORT_SYM void set_servo_position	(	int	servo,
		int	position
	)

Parameters

servo	The port of the servo
position	The new servo position, between 0 and 1023

Note

Even though the servos have a theoretical range between 0 and 1024, the actual range is often less. Setting the servo to a position that it cannot physically reach will cause the servo to audibly strain and will consume battery very quickly.
