PIO testing

Hi guys, I'm new to the uClinux, just got it to work and ran the traditional "Hello World" app :rolleyes: now I'm trying something new so before I get tangled, quick q to access a PI...

hmmm no. I don't think it's created in the same folder

I made a simple "hello world" kernel module

it worked but I didn't see it's .ko file in the same folder either

btw, if I have a kernel module for pio (assuming it works)

do I use "fopen"/"fclose" in my app to open/close a device file (like /dev/pio_buttons)?

is it that simple? :huh:
