I am having trouble with the code for relays. I have defined them under Public Partial Class Program as “Static.GTM.Seeed.Relays LEDs;”
I have 3 Glide screens for UI on the T35 display held in index and I need to have certain relays on and off depending on what screen is showing on the T35.
When I use “LEDs.Relay1 = True;” whithin “if index == 0” there are no errors in the errors box but when I deploy the program to the Spider it throws an unhandled exception relating to the “LEDs.Relay1 = True” line.
Ok I tested the relays in separate solution and they work properly just using “relays.Relay1 = True;” and so on. The problem I having is finding the correct place to put my relay events. The program I am running is mostly related to the touch screens and Glide. I need certain relays to turn on and off depending on which of my 3 screens are up on the T35.
I need to find the correct place and way to say:
if window index = 0
relays.Relay1 = true

I have tried calling the relays within the Windows Index arguments and it red lines them.
I have tried defining the relays as GTM.Seed.Relays LEDs and then calling LEDs.Relay1 = True and it will accept that but then throw an unhandeled exception when I deploy to the Spider.
I don’t have the experience to know anything else to try.
The code I posted is the actual programming that is working without any code or deployment errors. I’m a beginner and I’m sorry but I don’t know to post code using code tags so it appears the same way as in the program cs.
The closest I’ve gotten to getting the relay code to work in this program is by adding this deffinition before “Program Started”;
// First window
if (index == 0)
{
UI.Button backBtn = (UI.Button)window.GetChildByName("backBtn");
backBtn.Enabled = false;
// Disabling a button reduces it's alpha to 1/3 it's current value.
// Simply invalidating a button won't show the alpha change because
// it's redrawing over the current bitmap. To show this change we need
// to clear the region it occupies (fill it with background color).
window.FillRect(backBtn.Rect);
backBtn.Invalidate();
LEDs.Relay1 = true;
I get no errors in the program cs doing this but when I deploy I get an unhandeled exception pop up and it highlights the LEDs.Relay1 = true; line.
but I cannot figure out how or where to put these events in order to get them sinc up with the windows index. I’ve tried if and while index = statements and they don’t produce erros but still once deployed, the relays do not change status when I advance forward and backward through the screens.
Here is what I’ve tried and the relays do not change state when I advance the screens. On boot up relay1 comes on and stays on no matter what screen I advance to.

windows[0] = GlideLoader.LoadWindow(Resources.GetString(Resources.StringResources.Window1));
windows[1] = GlideLoader.LoadWindow(Resources.GetString(Resources.StringResources.Window2));
windows[2] = GlideLoader.LoadWindow(Resources.GetString(Resources.StringResources.Window3));
// Activate touch
GlideTouch.Initialize();
// Initialize the windows.
InitWin1(windows[0]);
InitWin2(windows[1]);
InitWin3(windows[2]);
updateNavButtons();
// Assigning a window to MainWindow flushes it to the screen.
// This also starts event handling on the window.
Glide.MainWindow = windows[index];
Piezo = eBlockExpansion1.SetupPWMOutput(GT.Socket.Pin.Nine);
switch(index)
{
case 0:
relays.Relay1 = true;
relays.Relay2 = false;
relays.Relay3 = false;
relays.Relay4 = false;
break;
case 1:
relays.Relay1 = false;
relays.Relay2 = true;
relays.Relay3 = false;
relays.Relay4 = false;
break;
case 2:
relays.Relay1 = false;
relays.Relay2 = false;
relays.Relay3 = true;
relays.Relay4 = true;
break;
}
Debug.Print("Program Started");
}
I will try the second example as well. I wonder if it would be better to attach the relay events to the touch screen “next” and “back” tapOn events?
