Application of Embedded Linux Boards in SSRF and SXFEL Control System

The embedded Linux boards, such as Raspberry Pi B+ and BeagleBone Black, are credit-card-sized single-board computer. They are low-cost and equipped with a huge array of GPIO (General Purpose Input Output), which can be used to take readings from sensors and control external devices. The active development community and opensource nature also make them ideal choices for many applications. They can be integrated with the accelerator control system and make more devices 'intelligent' via an economical way. It will be helpful to improve the efficiency of the accelerator. The details of the applications in SSRF and SXFEL control system will be reported in this paper.
