Function Documentation

◆ Dynamixel_Action()

void Dynamixel_Action ( Dynamixel_HandleTypeDef * hdynamixel )

Implementation of the ACTION instruction.

This triggers the instruction registered by the REG WRITE instruction. This way, time delays can be reduced for the concurrent motion of several motors

Parameters

hdynamixel pointer to a Dynamixel_HandleTypeDef structure that contains the configuration information for the motor

Returns: None

◆ Dynamixel_EnterJointMode()

void Dynamixel_EnterJointMode ( Dynamixel_HandleTypeDef * hdynamixel )

Sets the control registers such that the rotational angle of the motor is constrained between the default values.

Parameters

void Dynamixel_EnterWheelMode	(	Dynamixel_HandleTypeDef *	hdynamixel,
		float	goalVelocity
	)

Sets the control registers such that the rotational angle of the motor is not bounded.

When the angle limits are both set to 0, then motor will attempt to rotate with maximum velocity. To prevent undesired behaviour, the goal velocity should be set right after calling this function

A value of 0-1023 gets translated into a counterclockwise load (positive), and a value of 1024-2047 gets translated into a clockwise load (negative). The results are written to hdynamixel -> _lastLoad, and hdynamixel -> _lastReadIsValid is set if the checksum is verified, and is cleared otherwise
