Signal: Help button, with support message

[MisterChalmers]

set dial button as a support button

• if you hold down button for 5 seconds a special page comes up that says "SENDING FOR SUPPORT IN 5...4....3...2..1.."
  • then it sends chalmersproject a telegram message or something with the shelter name that asked for help

diagram on chalmers signal explaining you can hold down dial to send a HELP! SUPPORT message to chalmersproject

---

i've created a GuiSlice Page to trigger when button is pressed.
I'm creating an interrupt for when button is pressed.

added this to setup and also this interrupt

void ICACHE_RAM_ATTR encoder_button_trigger()
{
  encoder_button_pressed = true;
  Serial.println("encoder button pressed!");
}

//...

void setup()
{
//...
attachInterrupt(digitalPinToInterrupt(5), encoder_button_trigger, ONLOW);
//...
}
