Preface Raspberry Pi (Raspberry pi,rpi) is designed for students ' computer programming education, only card-sized card computers that can run Linux or Windows IoT core operating systems. This article uses the Raspberry Pi and UWP (Universal Windows Platform) development technology to build a weather station system that can be monitored in real time. Hardware and technology involved 　　 Hardware section: Raspberry Pi 2 or 31 blocks, 8G or more m

Transferred from: http://blog.csdn.net/mirkerson/article/details/8464290An overviewThe Gpio in the Linux kernel is the simplest, most common resource (and interrupt, Dma,timer) driver, the application is able to use the corresponding interface using Gpio,gpio to use the integer ID between 0~max_int, can not use negative numbers,

Through the Sysfs control Gpio, first access to the/sys/class/gpio directory, the export file to write the Gpio number, so that the Gpio operation interface from the kernel space exposed to the user space, Gpio operating interface including direction and value, etc. The dire

If it returns -1 then the initialisation of the GPIO have failed, and you should consult the global errno To see why.The differences between the setup functions is as follows: Wiringpisetup (void); This initialises the WIRINGPI system and assumes, the calling program are going to be using the WIRINGPI pin n Umbering scheme. This was a simplified numbering scheme which provides a mapping from virtual PIN number
