Hello User

This sketch is the first thing you see when starting the robot. It gives you a warm welcome, shows you some of its really amazing features, and lets you personalize some data.

Hardware Required

Arduino Robot

Instruction

Upload the example, you can keep the USB plugged.
After the starting screen, you'll see a sequence of slides, read through them to see how this example works.
When it comes to the input step, a virtual keyboard will show up on the bottom half of the TFT.
You can use the knob and buttons to select your input.
Use the knob to select key
Press the middle button to input the key selected
Press left/right buttons to move the cursor around
When you're done with an input, input "Enter" on the virtual keyboard
If you want to erase a character, move the cursor to the desired position, and input an empty space to make it disappear.
There's a secret hidden in this example, find it out!

/**

textManager mostly contains helper functions for

R06_Wheel_Calibration and R01_Hello_User.

The ones used in this example:

  textManager.setMargin(margin_left, margin_top):

    Configure the left and top margin for text

    display. The margins will be used for

    textManager.writeText().

    Parameters:

      margin_left, margin_top: the margin values

      from the top and left side of the screen.

    Returns:

      none

  textManager.writeScript(script_number,line,column):

    Display a script of Hello User example.

    Parameters:

      script_number: an int value representing the

        script to be displayed.

      line, column: in which line,column is the script

        displayed. Same as writeText().

    Returns:

      none

  textManager.input(line,column,codename):

    Print an input indicator(">") in the line and column,

    dispaly and receive input from a virtual keyboard,

    and save the value into EEPROM represented by codename

    Parameters:

      line,column: int values represents where the input

        starts. Same as wirteText().

      codename: either USERNAME,ROBOTNAME,CITYNAME or

        COUNTRYNAME. You can call Robot.userNameRead(),

        robotNameRead(),cityNameRead() or countryNameRead()

        to access the values later.

    Returns:

      none;

  textManager.writeText(line,column,text):

    Display text on the specific line and column.

    It's different from Robot.text() as the later

    uses pixels for positioning the text.

    Parameters:

      line:in which line is the text displayed. Each line

        is 10px high.

      column:in which column is the text displayed. Each

        column is 8px wide.

      text:a char array(string) of the text to be displayed.

    Returns:

      none

    textManager.showPicture(filename, x, y):

      It has the same functionality as Robot.drawPicture(),

      while fixing the conflict between drawPicture() and

      sound playing. Using Robot.drawPicture(), it'll have

      glitches when playing sound at the same time. Using

      showPicture(), it'll stop sound when displaying

      picture, so preventing the problem.

      Parameters:

        filename:string, name of the bmp file in sd

        x,y: int values, position of the picture

      Returns:

        none
