[Gumstix-users] First time using Breakout-vx with Verdex-Pro XL6P

[Ben D. <bd...@kb...>]

I have some questions for this is my first time working with GPIO's as well
as the Gumstix. I see that there are 4 LED's that can be used on the
breakout-vx board. (Down by the RJ45) I also know that these 4 LED's go over
to the pin holes right next to them with the matching color. I have been
playing around with this for a couple days now and I think I know how to get
these LEDs to light up, correct me if I'm wrong. The way I got them to work
is by connecting a wire from a pin hole to a GND point and the LED would
light up. I hope that is the way they are supposed to work. Onto my
question, I want to hook 2 of these up to a GPIO and have one of them turn
on when a switch it pushed. Is this possible to do? If so would I need to
put in a resistor to limit the current to the GPIO? Can someone please
explain in detail how I would wire this up if it can be done.

Question 2:
I also want to install a external switch to a GPIO so that when it is
pressed the program will perform a task that is addressed with that GPIO.
How would I go about doing this as far as wiring it up. I have read stuff
about using a zener diode and resistors. Not sure what I really need to do
for this to work. Detailed steps would be great.

As far as the programing goes for this i'm not doing that, a programmer is
writing the program for the gumstix. I'm just working on the wiring of the
switches and LEDs. Any help would be great and thanks again.
