Servo

This driver is designed to control a servo motor via PWM (Pulse Width Modulation) signals. It allows for precise positioning of the servo arm by varying the duty cycle of the PWM signal.

Initialization

void ServoInit(Pwm_ChannelType ServoPwmChannel, uint16 MaxDutyCycle, uint16 MinDutyCycle, uint16 MedDutyCycle);

This must be called before any other servo function in your program. The function sets the servo to its neutral position after initialization.

Parameters:

· MaxDutyCycle: The maximum duty cycle, which corresponds to the servo’s maximum rotation angle.

· MinDutyCycle: The minimum duty cycle, corresponding to the servo’s minimum rotation angle.

· MedDutyCycle: The medium duty cycle, representing the neutral or center position of the servo.

Steering

void Steer(int Direction);

This function is used for setting specific steering angles. It takes integer values between -100 and 100, with -100 being full left and 100 being full right.

Parameters:

· Direction: Positive Direction values turn the servo right, and negative values turn it left.

Predefined steering angles

void SteerLeft(void);
void SteerRight(void);
void SteerStraight(void);

· SteerLeft: Moves the servo to its maximum rotation angle (left).

· SteerRight: Moves the servo to its minimum rotation angle (right).

· SteerStraight: Aligns the servo to its neutral position (center).
