Detailed Description

Class to drive one servo in continuous rotation mode.

This class allows to drive one servo in continuous rotation mode.

Constructor & Destructor Documentation

HkxContRotation::HkxContRotation	(	uint8_t	ID,
		HkxCommunication &	herkXCom,
		HkxPrint &	print
	)

Constructor.

The constructor of HkxContRotation.

Parameters

[in]	ID	: id of the servo to drive. The value shall be [0 ; 253].
[in]	herkXCom	: Communication with the servos.
[in]	print	: Communication to print messages.

Example:

HkxPrint print = HkxPrint(Serial, 9600); 
HkxCommunication communication = HkxCommunication(HKX_115200, Serial1, print); 
HkxContRotation servo = HkxContRotation(10, communication, print); // ID=10, print can be different to communication

Member Function Documentation

uint8_t HkxContRotation::clearStatus ( )

Clear the status.

Clear the status of the servo to leave the "error state" and stop the LED blink and torque deactivation (see p.33 of the user manual for more details about LED and torque policies).

Warning: If the problem still present (e.g. low input voltage), the servo will switch again to error just after clearing.

Returns: 0 = OK
1 = Input not correct
2 = Servo not connected

Example:

... 
HkxContRotation servo = HkxContRotation(10, communication, print);
HkxStatus currentStatus;
byte error = servo.getStatus(currentStatus, true);
if(error==0 && currentStatus.isError(HKX_STAT_ALL)){ // check if any error
  servo.clearStatus(); 
}

uint8_t HkxContRotation::getBehaviour	(	HkxMaybe< uint16_t >	inputVoltage,
		HkxMaybe< uint16_t >	temperature,
		HkxMaybe< int16_t >	velocity,
		HkxMaybe< int16_t >	PWM
	)

Get the servo behaviour.

Get the current servo behaviour. See the user manual for more details about the parameters.

Parameters

[out]	inputVoltage	: Current servo input voltage. Its value is given in millivolts. This parameter is optional, either set the address of a `uint16_t` (or `unsigned` `int`) variable to return the value, or set `HKX_NO_VALUE` to ignore it.
[out]	temperature	: Current temperature of the servo. Its value is given in 10^-2 °C (degree Celsius). This parameter is optional, either set the address of a `uint16_t` (or `unsigned` `int`) variable to return the value, or set `HKX_NO_VALUE` to ignore it.
[out]	velocity	: Current angle velocity of the servo. Its value is given in degree / second. This parameter is optional, either set the address of a `uint16_t` (or `unsigned` `int`) variable to return the value, or set `HKX_NO_VALUE` to ignore it.
[out]	PWM	: Current PWM (load) of the servo. Its value is given in PWM (raw). This parameter is optional, either set the address of a `int16_t` (or `int`) variable to return the value, or set `HKX_NO_VALUE` to ignore it.

Returns: 0 = OK
1 = Input not correct
2 = Servo not connected

uint16_t inputVoltage, temperature;
int16_t velocity, PWM;
servo->getBehaviour(&inputVoltage, &temperature, &velocity, &PWM);

...
byte idOfMyServo = servo.getID();

hkxLEDControl HkxContRotation::getLEDControl ( ) const

inline

Get LED control.

Get the current LED control (colour) of the driven servo (see hkxLEDControl for more details about the options).

Returns: Return the LED control.

Example:

hkxLEDControl ledControlOfMyServo = servo.getLEDControl();

uint8_t HkxContRotation::getStatus	(	HkxStatus &	statusED,
		boolean	update
	)

Get the status.

Get the last received status from the servo.

Parameters

[out]	statusED	: Last received status of the servo.
[out]	update	: `true` to update the status, then to get the current status. `false` to get the last received status.

Returns: 0 = OK
1 = Input not correct
2 = Servo not connected
3 = Data not consistent

Example:

... 
HkxContRotation servo = HkxContRotation(10, communication, print);
HkxStatus currentStatus;
byte error = servo.getStatus(currentStatus, true);
if(error==0 && currentStatus.isError(HKX_STAT_VOLTAGE)){ // check voltage error
  print.errorPrint(F("Please check input voltage")); 
}

hkxTorqueControl HkxContRotation::getTorqueControl ( ) const

inline

Get torque control.

Get the current torque control of the driven servo (see hkxTorqueControl for more details about the options).

Returns: Return the torque control

Example:

... 
HkxContRotation servo = HkxContRotation(10, communication, print);
hkxTorqueControl torqueControlOfMyServo = servo.getTorqueControl();

boolean HkxContRotation::isStopped ( )

Reboot the servo. This action will erase the ram, then reinitialize the parameters with the EEP (ROM) values. Wait some time (> 500 ms) before asking any action from the servo.

Returns: 0 = OK
2 = Servo not connected

Example:

... 
HkxContRotation servo = HkxContRotation(10, communication, print);
servo->reboot();
wait(500); // wait for the servo to restart

[in]	newLEDControl	: LED control to apply. This parameter is optional, either set a hkxLEDControl variable, the value (list below), or set `HKX_NO_VALUE` to ignore it. `HKX_LED_OFF`, `HKX_LED_GREEN`, `HKX_LED_BLUE`, `HKX_LED_RED`, `HKX_LED_CYAN`, `HKX_LED_YELLOW`, `HKX_LED_PINK`, `HKX_LED_WHITE`,
