You
have to find the pinctrl
register in the TRM and then match the offset 0x150 to the table and
double check that it is SPI.
Request help for these trivial questions.

Thank you in advance.
If you're happy using C then libsoc[1] can do this for you in a simple C
program. If you wish to do it in another language looking at the gpio
code in libsoc will show you the basics of how to do it.
Cheers,

Hi,
I got my BBB few days ago and decided to do something to help the

real pain when using Linux and accessing them inside a C application, so
I decided to write an arduino

using the mainline kernel at the moment so you might be able to leverage
that to get some help.
Good luck!

I am afraid PU/PD settings are controlled by device tree, so you will
have to use them! You will be able to easily edit your current device
tree to change it, assuming you aren't using the default pin state. If
you are using the default pin state, then I would strongly recommend

The issue isn't really with _who_ turns the LED on and off, that is a

to the program telling it turn on/off an
LED. The C program runs as root and as such has control of the hardware
and your webapge never calls the C program, but only sends data on the
message bus, so as such it's a bit harder for anyone to do anything
untoward.

and executed in a real time deterministic manner. You could
also use a bare-metal implementation to gain real-time functionality, or
try Xenomai.
So the answer is Yes, and No. More research on your behalf is needed
into the requirements of your specification.
