Hey all, I am pretty new to the BBB and I came across something pretty odd that I have been trying to figure out for a few hours now as I was creating a push button circuit:
P9_25 is a GPIO pin. I set it to input but noticed that it would not respond to my button. After some digging I realized that the pin itself was acting funky, so I isolated it to run some tests with BB's Bonescript tutorial on GPIO digitalWrite(). I ran this code below (apologies for the sloppy picture) with the adjacent circuit configuration shown as well. Obviously, the LED should turn off, but it doesn't: <https://lh3.googleusercontent.com/-UVZwTNBSR00/VZ3RjMNpQiI/AAAAAAAAAGM/mjWtyKl5LTw/s1600/20150708_212210.jpg> <https://lh3.googleusercontent.com/-lmn1_9_NGTM/VZ3PwVv6MLI/AAAAAAAAAF4/-yVeDLNf7fY/s1600/20150708_212158.jpg> I then tried the same tests on other pins, such as P9_26, and it worked perfectly, so that's where I'm startled. I have two theories: 1) I messed with P9_25 in the past, and it is reconfigured in a weird way; if someone has this hunch, could you please perhaps inform me how to reset the pin to its original glory? 2) The pin is busted. Fingers crossed for #1. If anybody has run into something similar, or has any idea what I should do, please let me know! Thank you for you time. -Joe -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
