:).-----------------------------to spit out the installation experience-----------------------------------------------------Today, there is a project to do a self-running measurement system, thinking about how to implement automatic measurement when not connected to the PC. The previous day has been the Python GUI, so think of the idle raspberry Pi, perhaps with

Introduced The DHT11 is a cheap accessory that includes temperature and humidity sensors, and the code is easy to use. This article describes if you use DHT11 in a Raspberry Pi, the code is python.

linux applications. the reason is very simple. perl is fading out, ruby is not powerful, shell is not enough, php is not suitable, and java is not explained. I remember that the Redhat 7 character interface installer was written in python, which was almost the first time I heard about python. it was very powerful, easy to use, and easy to modify and adjust. Don't waste time and energy on things unrelated

RPI the compiler installed by default is gcc-4.6.2Now the latest C + + Libsockets library needs to use compilers that support the C++-11 feature, which requires 4.8.2. To do this, you need to upgrade the compiler before you can support compilation.You also need cmake to generate the makefile fileThe steps are as follows:1. Download the source code:2, installation CMakeInstall3, upgrade the compiler to 4.8.2Tutorial Links: http://www.cnblogs.com/sn-dnv
