As for how to burn Raspberry Pi's system to the SD card, we will not continue to talk about it here. There are many introductory articles to explain and explain. This article mainly introduces how to build a programming platform that facilitates interaction with the Windows platform, and operate GPIO

At this step, OpenCV should have been installed in/usr/local/lib/python2.7/site-packages.
However, to use OpenCV in the cv virtual environment, we first need to match the link to our site-packages directory:
$ cd ~/.virtualenvs/cv/lib/python2.7/site-packages/$ ln -s /usr/local/lib/python2.7/site-packages/cv2.so cv2.so$ ln -s /usr/local/lib
the cv virtual environment, we first need to match the link to our site-packages directory:
$ cd ~/.virtualenvs/cv/lib/python2.7/site-packages/$ ln -s /usr/local/lib/python2.7/site-packages/cv2.so cv2.so$ ln -s /usr/local/lib/python2.7/site-packages/cv.py cv.py
Step 11:
Finally, let's test the installation of OpenCV and Python:
$ workon cv$ python>>> import cv2>>> cv2.__version__'2.4.10'
OpenCV and Python have been successfully installed on your Raspberry

After buying the Raspberry Pi, what can I do with it? There are a few ideas to share with the beginner's teaching film, which is well worth a visit. Http://www.youtube.com/user/RaspberryPiBeginners 1.Plug in the expansion card, DIY or teaching.The main usage, of course, is to plug in a GPIO card, put on a noodle board, pull some electrical circuit, control what the LEDs are showing, or produce beer (http://
controlling physical devices over the Internet is a powerful and exciting thing, and the Raspberry Pi comes from this idea. There are a lot of great examples on our blog.Note: Not really in any place, of course you need to connect some things to the network, connected to the Internet computer and electricity. So don't give us a letter because of this:)# # How do
