Greetings all, I've been playing with software and hardware for 30+ years, but I'm new to Linux and embedded Linux systems. The code snippets I've been able to find for GPIO access all seem use file I/O functions. I've never seen this approach before -- I'm accustomed to reading and writing processor registers. The file I/O approach seems strange to me, but I'm new here, and there's a *lot *that seems strange.
So, can someone explain why the file I/O approach is used? Is this a typical technique for Linux systems, or something particular to ARM processors? I suppose it doesn't really matter, but I prefer to understand why things are done as they are. Thanks very much, folks.
