下图是 Orange Pi 3 的 GPIO 引脚功能图
激活 GPIO 模块
modprobe gpio-sunxi
要安装正确版本 的 WiringOP
要先下载 安装git
apt-get install git-core
下载 wiringop
wiringop是基于wiringpi的适配版本 ，GitHub 地址 https://github.com/orangepi-xunlong/WiringOP
git clone https://github.com/orangepi-xunlong/wiringOP.git
cd WiringOP chmod +x ./build sudo ./build
即可安装 Orange Pi 3版本的 WiringPi
测试是否正常安装
gpio readall
出现引脚图说明正常安装
点亮一个小灯
随便找个地方 新建文件，文件名 test.c
#include <wiringPi.h> int main (void) { int a=122; //gpio口 wiringPiSetup () ; pinMode (a, OUTPUT) ; for (;;) { digitalWrite (a, HIGH) ; delay (500) ; digitalWrite (a, LOW) ; delay (500) ; } return 0 ; }
正极放在 pin 3，pin 3 的 gpio 编号为 122,可以随意更改
阴极放在 GND ，pin 6
编译运行
gcc -Wall -o test test.c -lwiringPi
sudo ./test
劝君别买OrangePi
I simply wanted to thank you so much once more. I am not sure the things that I would've made to happen without those ways shown by you relating to this topic. This was the troublesome situation in my view, nevertheless witnessing your well-written way you treated the issue took me to weep with joy.
