Template:FAQ/Questions/examples available on how

Are examples available on how to read/write the GPIO's ( not by /proc/gpio ... ) from a library?
Access the GPIOs should not be needed directly. The LCD driver in the linux kernel will do this. Compile in the LCD driver, and specify the LCD screen timing parameters that the driver needs to know about, which can be done on the kernel command line, or by hardcoding the parameters into the module.

However, it is still possible to access the GPIO pins directly. Examples can be found at GPIO
