wiringOP安装方法

1. 下载wiringOP 的代码

apt update
apt -y install git 
git clone https://github.com/orangepi-xunlong/wiringOP

2. 编译wiringOP

cd wiringOP
./build clean
./build

3. 测试
   
   gpio readall
   
   命令的输出如下
   
   

OrangePi.GPIO安装方法

官方版本 OPi.GPIO-0.5.2

#明显看出来是python3.6
root@orangepi:~# whereis python
python: /usr/bin/python3.6 /usr/bin/python3.6m /usr/lib/python3.7 /usr/lib/python3.6 /usr/lib/python2.7 /etc/python3.6 /usr/local/lib/python3.6
#先安装python3.6对应的pip3
root@orangepi:~# sudo apt-get install python3-pip
#根据官方文档安装：
root@orangepi:~# sudo pip3 install --upgrade OPi.GPIO
#官方OPi.GPIO 版本为 OPi.GPIO-0.5.2

非官方版本 OPi.GPIO-0.6.6

1.安装python 开发包,和git ,安装过的可以忽略

sudo apt-get install python3-dev git

如果python3-dev安装失败，请参考：


https://www.cnblogs.com/ymjyqsx/p/6194968.html



2.下载代码

git clone https://github.com/Pako2/OrangePi.GPIO.git
cd ./OrangePi.GPIO

3.编译安装

sudo python3 setup.py install --force-h5 #使用此方式失败
# H6是芯片型号 需要指定
#如果编译失败,python 请试下
sudo python3 setup.py install_lib #可以编译成功

python调用例子

blink_led.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import OPi.GPIO as GPIO
from time import sleep          # this lets us have a time delay

GPIO.setboard(GPIO.PCPCPLUS)    # Orange Pi PC board
GPIO.setmode(GPIO.BOARD)        # set up BOARD BCM numbering
GPIO.setup(7, GPIO.OUT)         # set BCM7 (pin 26) as an output (LED)

try:
    print ("Press CTRL+C to exit")
    while True:
        GPIO.output(7, 1)       # set port/pin value to 1/HIGH/True
        sleep(0.1)

        sleep(0.5)

except KeyboardInterrupt:

    GPIO.cleanup()              # Clean GPIO
    print ("Bye.")

并测试针脚电压变化后的响应情况

# !/usr/bin/env python3

import OPi.GPIO as GPIO #引入刚刚我们安装的GPIO包
import time

touchPin = 5 #测试的针脚

# 定义一个回调函数,当检测到指定口的电压出现变化时触发
def getResonse(self):
    print("getResonse")
    if GPIO.input(touchPin)==1:
        print("Rising")
    else:
        print("Falling")

GPIO.setboard(GPIO.LITE2) #指定开发板型号
GPIO.setmode(GPIO.BOARD) #指定使用 BOARD 编号系统
GPIO.setup(touchPin, GPIO.IN) #设置为输入模式

GPIO.add_event_detect(touchPin,GPIO.BOTH,callback=getResonse,bouncetime=300)  #注册一个检测电压改变事件

print('开始检测')

#开启循环防止进程结束
runTime=0
while True:
    time.sleep(4)  ##进行挂起4秒
    print("running")
    runTime=runTime+1
    if runTime>5:
        break

GPIO.cleanup() #脚本结束后进行清理
print('Finish')
