Detailed Description

MG996R servo motor API definition.

This file offers the API required for working with the MG996R servo motor.

Macro Definition Documentation

MSEC_TO_NSEC

#define MSEC_TO_NSEC

(

x

)

((x) * NSEC_PER_MSEC)

convert miliseconds to nanoseconds

SERVO_MAX_ANGLE

#define SERVO_MAX_ANGLE   180

maximum angle supported by the servo

SERVO_MSEC_LEFT

#define SERVO_MSEC_LEFT   MSEC_TO_NSEC(1.0f)

1ms PWM duty cycle means the servo is in the most left position

SERVO_MSEC_RIGHT

#define SERVO_MSEC_RIGHT   MSEC_TO_NSEC(2.0f)

2ms PWM duty cycle means the servo is in the most right position

Function Documentation

servo_set_angle()

int servo_set_angle	(	struct nxp_servo *	servo,
		uint32_t	angle
	)

Set the angle of the servo motor.

Parameters

servo	pointer to the structure representing the MG996R servo motor
angle	angle to set (between 0 and 180 degrees)

Return values

0	on success
negative	errno code if failure
