Some test code for sending commands to the EBB

Test.cpp

//Hi Brian
//I'm running into those same issues, hopefully you might be able to point out something basic I'm doing wrong.
//To give you an overview, during this testing phase I've created a container that will hold a list of the string commands I want to execute, it's called mCommandStack.  Pressing any of the arrow keys pushes the corresponding command onto the stack.

//This is the code in my keyDown method:

        case 273:

            cout << "Moving up!" << endl;

            //mSerial->writeString("SM,1000,0,3000\r");

            addCommand("SM,1000,0,3000\n\r");

            break;

            

        

        case 274:

            cout << "Moving down!" << endl;

            //mSerial->writeString("SM,1000,0,-3000\r");

            addCommand("SM,1000,0,-3000\n\r");

            

            break;

        

        case 275:

            cout << "Moving right!" << endl;

           // mSerial->writeString("SM,1000,3000,0\r");

            addCommand("SM,1000,3000,0\n\r");

            break;

        

        case 276:

            cout << "Moving left!" << endl;

            //mSerial->writeString("SM,1000,-3000,0\r");

            addCommand("SM,1000,-3000,0\n\r");

            break;



//where my addCommand() method is as follows:

void DrawBotTestApp::addCommand(string _command)

{

    mCommandStack.push_back(_command);

    cout << "number of commands in stack: " << mCommandStack.size() << endl;


}



Once I've cued up the desired number of moves, I invoke the executeStack() method, which looks like this:

void DrawBotTestApp::executeStack()

{

    

    cout << "executing " << mCommandStack.size() << " commands" << endl;

    for (int i = 0; i < mCommandStack.size(); i++)

    {

        mSerial->writeString(mCommandStack[i]);

        cout << "sending: " << mCommandStack[i] << endl;

    }

    

    cout << "flushing serial buffer" << endl;

    mSerial->flush();

    

    cout << "clearing stack" << endl;

    mCommandStack.clear();

    

    cout << mCommandStack.size() << " commands left in stack" << endl;

    


}



//If for example I'd like to "draw a square", I hit the arrow keys in this order:  Up, Right, Down, Left, then press the 'e' key to invoke the executeStack() method.

//The issue is that sometimes the board only executes three commands, or two, or only one. It seems to be random, although I will say that it never seems to execute all four.  The debug console messages look like this:

executing 4 commands

sending: SM,1000,0,-3000

sending: SM,1000,-3000,0

sending: SM,1000,0,3000

sending: SM,1000,3000,0

flushing serial buffer

clearing stack

0 commands left in stack

//Another interesting thing that happens is that often when I close the application, my "printhead" moves, almost as if it is executing a lost command stored internally somewhere on the board..

//any thoughts?
