A few friends suggested programming the control code as a kernel module but I am not quite sure I wish to jump into that.

Code C – [ expand ]. Enabling GPIO through registers in FriendlyARM mini board I want to write to a physical address to change the voltage of a pin using an ARM board- but in order to write to a glio address, I need to take a virtual address, and map it to the physical address using mmap. Even nice tasks will have to give up time to the kernel tasks, etc. I had seen samples of your general purpose program and tried to write a C code for it myself.

I cannot access any files even when running the code gpioo root user. How this is related to your PWM question is unclear, but you seem to mmini2440 up two different kernel driver areas You could do something like the code below through sysfs as per the Linux kernel gpio documentation.

You will of course need to make sure that your hardware gpio is supported by the Linux kernel.
