What's needed to work with the GPIO on RPi?
I'd like to work with a motion sensor, and would prefer to work with LC
instead Python if I can.
Not LC, but I came across a very nice Forth for the pi: supports C-code
primitives and has a GPIO example
Currently I ran

There is also Ubuntu Server Minimal 16.04 for Raspi3 ...

Too bad, since the Pi is

Thanks. Bookmarked for when I get back to that.
Right n
Forgot to mention, in case you are interested in WebIOPi,
there is a patch:
WebIOPi-0.7.1 Patch for Raspberry B+, Pi2, and Pi3

I had it running on Raspi2, but not yet on Raspi3.

Perhaps the best "library" to Raspi-GPIO, that may also
answer most of your technical questions (in the C-part).

Note the line in the C example that explains how to
make this "Raspi 1"-code working on a Raspi 2.
Especially for you the WebIOPi may be also i

I think you have to poll. This would be another feature that might go
on the list to be done with LCB.

What is "the file method"? How do I treat GPIO connections as file
paths? Somewhere in /proc?
Earlier you wrote:
Look at the comments
Richard,
You initial gut reaction is STILL correct. Currently the only solution
available to livecoders is the file method. The performance of this
solution is terrible and limits the types of real world problems that
can be solved with livecode and raspberry pi.
It would be wonderful if

I'll see if I can find that one on the DVDs.
What is the LC syntax for something like:
open file GPIO pin 6
Richard, Take a look at the code in the MasterLibrary. Look at the
comments in the library it self for how to solve the Accessing the GPIO
(of a raspberry pi) without "sudo" problem.

Using the GPIO is nothing else than writing zeros or ones to a file.
Nobody needs a library for that?
[Also there was a talk about that at the last LC US-conference.]
The problem is to use the *correct* files or pins numbering
respectively. This is hardware dependent, not a problem of using
LC or
It looks like you could do this very easily in script. A good community project
to write a library and see what you can do with it!
