[SOLVED] Pins controlled by udoo thats needed by arduino?

Hi,
So i finally have started building my 3d printer, using udoo quad and radds 1.5. There is ofcourse some bugtesting to be done. And one of the problems im having now is that the udoo is restarting itself, when im activating MIN-Y and MAX-Y endstop.
Im using the reprap mechanical endstops:

Connected with 3 wires to the radds. I know there was something about only needing signal and gnd in the radds documention. But i figured you needed the last one to get the led to work. And for the X-Axis. they seem to work fine. Lighting up when i click it.

I had someone on another forum guessing that it might have something todo with pins being reserved for udoo when its needed for arduino.

anyone have any idea why this is?

 

On which OS are you running? And to what pins are the switches connected?

 

Its running udoobuntu 2.0
Its connected into an arduino shield so im not sure on what pins, how do i figure that out?

 

In the manual I guess. What if you do not connect the third wire of the switch as the manual states?

 

Well i feel like a propper idiot now.... In all my haste i didnt realize that the 3 pin connector was 180 degrees wrong on those that made it reboot :<

But it is working now!

thanks for the help

 

It had to be something that simple. Good that it works now.
