[#NETMF] .net Gadgeteer, HowTo: display a chart in a display

Buenas

After 2 days in Paris where I could write little and learn a lot; Today we are going with a pure and simple code example

How to paint a chart in a display pixel to pixel with. Net Gadgeteer .

In this example we will use the following

Organized with the following schema:

I must emphasise the application code

line 19, at the press of the Button in addition to stop and start the timer, turn on and turn off the LED of the button
line 32, the routine that draws the chart is the most simple, increases a counter between 20 and 40 and then it decreases. There is also a second flag to control the vertical advance

   1: using GT = Gadgeteer;

2:

   3: namespace GadgeteerApp6

   4: {

   5:     public partial class Program

   6:     {

   7:         private uint _axisX = 20;

   8:         private uint _axisY = 20;

   9:         private GT.Timer _timer;

  10:         private bool _modeUp = true;

11:

  12:         void ProgramStarted()

  13:         {

  14:             button.ButtonPressed += ButtonButtonPressed;

  15:             _timer = new GT.Timer(200);

  16:             _timer.Tick += TimerTick;

  17:         }

18:

  19:         void ButtonButtonPressed(GT.Modules.GHIElectronics.Button sender, GT.Modules.GHIElectronics.Button.ButtonState state)

  20:         {

  21:             button.ToggleLED();

  22:             if (_timer.IsRunning)

  23:             {

  24:                 _timer.Stop();

  25:             }

  26:             else

  27:             {

  28:                 _timer.Start();

  29:             }

  30:         }

31:

  32:         void TimerTick(GT.Timer timer)

  33:         {

  34:             _axisY++;

  35:             if (_axisY + 10 > display_T35.SimpleGraphics.Height)

  36:             {

  37:                 display_T35.SimpleGraphics.Clear();

  38:                 _axisY = 20;

  39:             }

  40:             if (_modeUp && _axisX > 40)

  41:             {

  42:                 _modeUp = false;

  43:             }

  44:             if (!_modeUp && _axisX < 20)

  45:             {

  46:                 _modeUp = true;

  47:             }

  48:             if (_modeUp)

  49:             {

  50:                 _axisX++;

  51:             }

  52:             else

  53:             {

  54:                 _axisX--;

  55:             }

  56:             display_T35.SimpleGraphics.SetPixel(GT.Color.Green, _axisX, _axisY);

  57:             for (uint i = 1; i < 15; i++)

  58:             {

  59:                 display_T35.SimpleGraphics.SetPixel(GT.Color.Red, _axisX + i, _axisY);

  60:             }

  61:         }

  62:     }

  63: }

And already tomorrow to Santa Pola to show these things live with friends of GuseNet .
