Detailed Description
IRI ROS Specific Driver Class.
This class inherits from the IRI Base class IriBaseDriver, which provides the guidelines to implement any specific driver. The IriBaseDriver class offers an easy framework to integrate functional drivers implemented in C++ with the ROS driver structure. ROS driver_base state transitions are already managed by IriBaseDriver.
The IriJoystickDriver class must implement all specific driver requirements to safetely open, close, run and stop the driver at any time. It also must guarantee an accessible interface for all driver's parameters.
The IriJoystickConfig.cfg needs to be filled up with those parameters suitable to be changed dynamically by the ROS dyanmic reconfigure application. The implementation of the CIriNode class will manage those parameters through methods like postNodeOpenHook() and reconfigureNodeHook().

Member Typedef Documentation
| typedef iri_joystick::IriJoystickConfig IriJoystickDriver::Config |
define config type
Define a Config type with the IriJoystickConfig. All driver implementations will then use the same variable type Config.
Definition at line 79 of file iri_joystick_driver.h.
Constructor & Destructor Documentation
constructor
In this constructor parameters related to the specific driver can be initalized. Those parameters can be also set in the openDriver() function. Attributes from the main node driver class IriBaseDriver such as loop_rate, may be also overload here.
Definition at line 4 of file iri_joystick_driver.cpp.
Destructor.
This destructor is called when the object is about to be destroyed.
Definition at line 110 of file iri_joystick_driver.cpp.
Member Function Documentation
| bool IriJoystickDriver::closeDriver | ( | void | ) | [virtual] |
close driver
In this function, the driver must be closed. Variables related to the driver state must also be taken into account. This function is automatically called by IriBaseDriver::doClose(), an state transition is performed if return value equals true.
- Returns:
- bool successful
Implements iri_base_driver::IriBaseDriver.
Definition at line 39 of file iri_joystick_driver.cpp.
| void IriJoystickDriver::config_update | ( | const Config & | new_cfg, |
| uint32_t | level = 0 |
||
| ) |
config update
In this function the driver parameters must be updated with the input config variable. Then the new configuration state will be stored in the Config attribute.
- Parameters:
-
new_cfg the new driver configuration state level level in which the update is taken place

| void * | param = 0 |
||
| ) |
Definition at line 77 of file iri_joystick_driver.cpp.
| std::string IriJoystickDriver::get_device | ( | ) | const |
return the physical device string from driver
Definition at line 105 of file iri_joystick_driver.cpp.
| int IriJoystickDriver::get_num_axes | ( | ) | const |
Definition at line 99 of file iri_joystick_driver.cpp.
| int IriJoystickDriver::get_num_buttons | ( | ) | const |
return the total number of buttons as int
Definition at line 93 of file iri_joystick_driver.cpp.
| bool IriJoystickDriver::openDriver | ( | void | ) | [virtual] |
open driver
In this function, the driver must be openned. Openning errors must be taken into account. This function is automatically called by IriBaseDriver::doOpen(), an state transition is performed if return value equals true.
- Returns:
- bool successful
Implements iri_base_driver::IriBaseDriver.
Definition at line 23 of file iri_joystick_driver.cpp.
| bool IriJoystickDriver::startDriver | ( | void | ) | [virtual] |
start driver
After this function, the driver and its thread will be started. The driver and related variables should be properly setup. This function is automatically called by IriBaseDriver::doStart(), an state transition is performed if return value equals true.
- Returns:
- bool successful
Implements iri_base_driver::IriBaseDriver.
Definition at line 54 of file iri_joystick_driver.cpp.
| bool IriJoystickDriver::stopDriver | ( | void | ) | [virtual] |
start driver
After this function, the driver's thread will stop its execution. The driver and related variables should be properly setup. This function is automatically called by IriBaseDriver::doStop(), an state transition is performed if return value equals true.
- Returns:
- bool successful
Implements iri_base_driver::IriBaseDriver.
Definition at line 59 of file iri_joystick_driver.cpp.

config variable
This variable has all the driver parameters defined in the cfg config file. Is updated everytime function config_update() is called.
