I am looking for some help from some of you with unix/raspberry pi experience.
I have think that I have installed 7.0 rc 1 on my raspberry pi B+ properly. I
am trying to figure out how to play with the GPIO’s.
I am am able to execute the following to set up the IO
put shell("echo 12 > /sys/class/gpio/export") into dummy
dummy is empty, However the next statement:
put shell("echo out > /sys/class/gpio/gpio12/direction") into dummy
dummy contains the error message:
bin/sh: cannot create /sys/class/gpio/gpio12/direction: Directory
nonexistent
When I use the terminal, I can see that the directory does exist and I am able
to modify the contents to both set the IO direction and sucessfully turn the
LED on and off.
Could it be that I do not have the permission to create directories and modify
files from livecode? How can I check this from livecode and fix it? ….
assuming this is in fact a permission issue.
Thanks,
Mike
