Driver details for I2C,SPI and GPIO on Raspbian

[sumanharapanahalli]

Hello Guy's,

I have received my pi recently, I want to use the in built driver of the I2C and GPIO.
Can someone help me find how can I use drivers using C program, or is there any documentation on this drivers or the source code path of the same may also be helpful.

I am willing to interface a touch screen using the same.
Regards
Suman

and

Hello Joan,
thx for your quick response. But all examples are showing how to access the I2C bus with python or C.
I search for a way that allows the access with ruby on rails.

I know nothing of Ruby. Can't you open/read/write/close files in Ruby? If you can then use the same methods to open/read/write/close the I2C file. If Ruby can't work with files then I'd suggest you use a different programming language.
