E_stop and E-stop reset

Projects Programming
1

Hi,

I have two momentary switches one for E-stop and one for E-stop reset.

So I have two pins that go high when each of the buttons is pressed.

Anyone have an idea on how I can halt the program when the Estop is pushed and resume when the Estop reset is pushed?

I was thinking about using Switch/case but not sure how to actually do it. Any help would be appreciated..

Thanks
Dana

Momentary switch? That strikes me as a contradiction to "emergency". Are you building an emergency stop?

No, it is actually on a machine. I can switch it to a normal palm button, but I would like to keep it all original.

I got it to work with simple If statements, seems to work.`



if (in_platform_estop == HIGH)    
  {
    digitalWrite (e_stop_pin, HIGH);   
  }

if (in_platform_estop_reset == HIGH)
  {
    digitalWrite (e_stop_pin, LOW);
  }
