The GPIO utility - Wiring Pi

Hellow I'm enthusiast newbie in linux kernel modules development. I started writing basic kernel modules that control Pi's gpio. But i came in to sticky situation i need to set pull up/down of pins and i can't find any function for that (I've been searching /include/linux directory whole day).

Which gpio pins have pull-up/down resistors? - Raspberry

When a GPIO pin is set as an input it is “floating” and has no defined voltage level. For us to be able to reliably detect whether the input is high or low we need to tie it so that it is always connected and either reads high or low. To tie the pin we connect either a Pull Up or Pull Down resistor.

Cheat Sheet - Physical Computing with Raspberry Pi

Remember that Raspberry GPIO pins are only 3. 3 V tolerant (so, do the pullup to 3. 3 V, not 5 V on the Raspberry Pi)!!! Here's an example of a pull-up resistor schematics. A pull-up will make sure the pin is up without taking in too much current.

Raspberry Pi GPIO Access - Raspberry Pi

The Raspberry Pi's GPIO pins are in two rows of 13 pins next to the RCA video socket. and there's another jumper cable linking that negative supply rail to a GND pin on the GPIO header. The resistor is used to pull up the voltage on pin 23 to logic 1. Without it, pin 23 would have an indeterminate value. See also: ://code. google

Introduction to accessing the Raspberry Pi's GPIO in C++

The Raspberry Pi offers up its GPIO over a standard male header on the board. Over the years the header has expanded from 26 pins to 40 pins while maintaining the original pinout. GPIO.
