It looks like you need to set the DISPLAY environment variable so that
tkinter knows which display to use.
Is X11 installed on the BBB?
On my linux machine, when I try echo $DISPLAY, I get ":0.0" without the
quotes.
What happens if you run that command?
You might check out some of the info on t

That's because it's the wrong test. type 'which test' and it'll probably
say /usr/bin/test. If you don't specify the path, it's using the PATH

First thing one needs to understand. Just because the hardware is a
beaglebone, does not mean it needs anything special in regards to
toolchain's. As long as the tools have an ABI compatible binary, we're
fine. The ABI it's self we do not really need to worry about. It's already

Hi Silwester!
What happens when you load the kernel module manually (sudo modprobe
uio_pruss)?
Does it create the interrupts (ls -l /dev/uio*)?
If not, do you get any messages in dmesg?

Not to belabor the point but I am in about the same situation as Brainiac.
Is there a cookbook guide to compiling, linking, and running C programs on
beaglebone? It seems that most BB folks are comfortable with linux
toolchain but many people come to this board with little linux knowledge,
eg. f
Hello friends,
I'm compilited this code for interface BBB with DHT11(temperature-humidity
sensor) this code is compiled and run successfully but OUTPUT
is

You do not have to. I've been trying to tell you all that umask is already
set by default. Screwing around with umask passed that is a recipe for
disaster. Unless you know exactly what you're doing, and then you do not
need to listen to me.
Again, it was a terrible idea to even bring up umask, as
Strange. I’m not sure there is a way to not use umask. With umask=022, the
purpose is to set the default permission for newly created files or
directories, so only the owner has write permissions. How is that a security
flaw? I guess you can always make umask=000, but then you are enabling every
