Hi,
I am trying to do some simple GPIO output, just to make sure that I can. So far, I have spent around three hours and still, no success. I have tried with both BoneScript and a Python library, and nothing has worked. So, now I have a few questions:
- Is there an easy way to figure out which pins are which? If so, how?
- How can I know which pins are reserved?
- Are we blocked from using pins that are reserved? If I addressed the wrong one, could I break something?
- How much power do the GPIO pins supply? Given what I would expect is a low amperage, could it break anything? (as I have probably demonstrated, I am not very experienced with electronics)
- Does the output change based on if the board is being powered off of USB or 5V barrel?
I hoe someone can supply some answers…
