This article mainly introduces how to use webiopi to control the GPIO pin level of raspberry pie, which has a certain reference value. Interested friends can refer to it. I hope you can learn a lot after reading this article.

1, you must install the python development version, that is, python-dev, otherwise many of the software will not be installed successfully, prompting the directory can not be found and so on.

one

Sudoapt-getinstallpython-dev

Under normal circumstances, the above online installation commands can be installed successfully, but unfortunately, the author in the installation, the online command to install resource pack 404.

Python2.7-dev_2.7.3~rc2-2.1_armhf.deb can not be found, and then can only manually find the following package installation.

two

Wget http://ftp.debian.org/debian/pool/main/p/python2.7/python2.7-dev_2.7.3-6_armhf.deb

Sudodpkg-I python2.7-dev_2.7.3-6_armhf.deb

2. Install the GPIO module of python

four

Wget http://raspberry-gpio-python.googlecode.com/files/RPi.GPIO-0.4.1a.tar.gz

Tar-xvzf RPi.GPIO-0.4.1a.tar.gz

CdRPi.GPIO-0.4.1a

Sudopython setup.pyinstall

3. Install webopio

Google Code project address: http://code.google.com/p/webiopi/

four

Wget http://webiopi.googlecode.com/files/WebIOPi-0.5.3.tar.gz

Tarxvzf WebIOPi-0.5.3.tar.gz

CdWebIOPi-0.5.3

Sudo./setup.sh

4. First set or modify the password of webopio

one

Sudowebiopi-passwd

The user name is: webiopi

If you do not change the password, the default password is: raspberry

5. Start webopio

one

Sudopython-m webiopi 8000

Port can be modified by itself. Default is 8000.

6. Let webopio run in the background, otherwise pressing ctarl+c will break it.

one

two

three

Sudo/etc/init.d/webiopistart

And

Sudo/etc/init.d/webiopistop

7. Set webopio to start with the system

one

Sudoupdate-rc.d webiopi defaults

8. Open the IP address to access the management interface with a browser

Http://192.168.1.106:8000/webiopi/

Control method:

a. Click "IN/OUT" on the outside to switch the working mode of GPIO, input / output

b. In output mode, click the number on the inside to switch the output level, high / low

c. In input mode, the internal test numbers represent the input status of GPIO
