How to enable I2C device http://www.cnblogs.com/hangxin1940/archive/2013/04/02/2997077.html and build a python I2C Development Environment http://www.cnblogs.com/hangxin1940/archive/2013/04/03/2997094.html Quick2wire is a python library used for I2C communication on Raspberry Pi. It allows non-root users to read and write gpio pins conveniently. Why use it? Some

" and he found a way to solve it. And my approach is to migrate the system to Openelec. This is something.Third, the use of TV remote control kodiCec:consumer Electronic control, literal translation into consumer electronics. It provides the use of remote controls to control devices connected via HDMI. And our Raspberry Pi and RASPBMC systems have been supported from both hardware and software levels. The n

The card computer boom triggered by Raspberry Pi has also led to the development of small-sized card computers by embedded developers in China. The well-known embedded developer in China, tianyinao technology and Feiling embedded system, also developed card computers. Now, we will compare the basic parameters of the embedded E8 chip computer with the OK335xS-II
