NanoPi S2 GPIO Mapping to access using SysFS

May 13th, 2017 No comments

In this post, I have mapped all the pins of Nano Pi S2 so that the GPIO can be easily accessed using SysFS.

This post is all about GPIO pin numbering to use with SysFS. In this post, I have mapped all the pins of Nano Pi S2 so that the GPIO can be easily accessed using SysFS. The pins are mapped according to the following formula,

sysfs pin number- X(GPIOX)+Y(GPIOXY)
Where,
X value depends on the GPIO group and is like below
GPIOA: 0
GPIOE: 128
GPIOALV: 160
GPIOB: 32
GPIOC: 64
GPIOD: 96
and Y is the pin number next to GPIO group name
