Configures and positions a servo in a given position (by degrees) The servo will lock its position as long as it is not stopped.
- Parameters
-
gptab | Servo channel (PWM GPT from 1-7) |
port | Port number to use as PWM |
pin | Pin number to use as PWM |
pos | Position to map the servo to (0-360ยบ, integer) |
- Returns
SERVO_SUCCESS
if successful, else SERVO_ERROR
