Introduction to Microcontrollers Mike Silva. I’m sorry to bring up this topic, but it’s very similar to what I need so i’ll just add my question here. I guess a question can’t get any more basic than this one. Thanks for the PI link. I know there must be tons of people using embedded Linux for years that know the answer to this.

Rain dance time, IH. Or is that really the only way to drive linnux darn GPIO port high and low? Create free account Forgot password? Pls, can anyone provide directions what to do? One pin will be left arrow, other will be right: A91 i looked for the linuxkernel in my buildroot directorie and read these files: Chronological Newest First Hi this should be trivial – but still too much for me.
On top of this, GPIO keys functionality can be used for user space programs.
If I had to write an application, how would I control this port? What includes are required then? How do i find or where is this table definig the banks?
Hope my problem is close to the ogirin topic of the post, and there are many developers who would find useful the problem solution I need. I would be interested in seeing some application implementation examples as well.
That is exactly what I was looking for. And now I don’t know, who is to blame, the hardware or may be the driver.

I should have titled the subject, “The most basic Linux questions in the world” to get the most eyes. Before Asking I’ve reviewed these documents: Introduction to Microcontrollers Mike Silva.

Hello Caglar, thanks for the swift reply. I am sure something is done in linux 2. If your applications are not using any GUI libraries then using sysfs is the most straightforward method.
Who is online Users browsing this forum: How to read a button? Is there a low level command in Linux that can access already known ports that will allow me to drive this port or a way to accomplish this without adding a new device with it’s own Linux driver? I eventually will need to drive some GPIOs high or low depending on a condition very slow binary status stuff. Following code snippet is taken from board-sam I guess a question can’t get any more basic than this one.
I would kindly appreciate any help in the issue.

If you want to use that code you can do either of these: Many AT91 evaluation kits uses this interface. Let’s say we want to use GPIO5 as output. Protecting the IoT with Invisible Keys. Sign in Sign in Remember pgio Forgot username or password? Thanks for the PI link.
