The first utility has a comand line user interface, being an easy example with only two DLL dependencies to the Visual C++ runtimes.
The second example utility has a graphic user interface created with QT Creator.
Here you can find the bin executables and the projects with the source code.
This is the main function of the first example, the command line:
[sourcecode language="cpp"]
int _tmain(int argc, _TCHAR* argv[])
{
cout << "AXControl_v2_VS_CPP test v0" << endl;
bool quit=false;
MyBasicSystem::BasicSystem mySystem;
UI ui(mySystem);
do
{
ui.showMenu();
int selected=ui.selectOption();
if (selected==ui.OptionQuit)
quit=true;
ui.executeSelectedOption(selected);
}while (!quit);
mySystem.dynamixelCommunication.close();
return 0;
}
[/sourcecode]
[Update] Yesterday I discovered a subtle but ugly bug. Can you spot it? Send an email to
if you can't find it but you want to know the danger bug.It use two classes, the "BasicSystem" (in the library "VS_CPP_AXControl_lib.lib") and a simple "UI" class that receives the input from the user and use the operations offered by the "BasicSystem" class.
For example:
[sourcecode language="cpp"]
int UI::getPosition()
{
int position=0;
do
{
cout << "Type a value between 0 and 1023 to set the AX-12 in that position" << endl; cin>>position;
}while(!validRange(position, 0, 1023));
cout << "Position:" << position << endl;
return position;
}
...
void UI::doSetPosition()
{
int ax12Id=getId();
int position=getPosition();
mySystem.dynamixelCommunication.sendOrder(ax12Id, MyCommunications::GoalPosition,(short) position);
}
[/sourcecode]
And all the cource code:
[sourcecode language="cpp"]

The code for the Qt version is more complex, but as an example, the same operation that the example for the command line:
[sourcecode language="cpp"] int MainWindow::getAX12_1_Id() { // Get the value from the edit control for the first AX-12 QString qStr=ui->SB_AX12_1_ID->text();
int id=Util::convertToInt(qStr.toStdString());
return id;
}
...
void MainWindow::on_B_AX12_1_SET_POS_clicked()
{
int id = getAX12_1_Id();
// Get the target position from the UI edit control as string and a convert it to int
short position= ui->SB_AX12_1_POS->text().toInt();
// Send the order to the AX-12 with the "id" to go to "position"
pDynComm->sendOrder(id, MyCommunications::GoalPosition,position);
}
[/sourcecode]
