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

NanoPi S2 The NanoPi S2(S2) is designed and developed by FriendlyElec for professionals, enterprise users, makers, and hobbyists. It is a small board with WiFi, Bluetooth, and eMMC. It uses the Samsung Quad Core Cortex-A9 S5P4418 SoC with dynamic frequency scaling up to 1.4GHz. It has 1G DDR3 RAM, 802.11 b/g/n WiFi & Bluetooth 4.0 module. Its inbuilt power management unit uses the AXP228 chip which supports software shutdown.
