Developing rc522 module based on c8t6 chip to realize breathing lamp

RC522 modular

 RFID , namely RFID yes Radio Frequency Ident ificat ion Abbreviation ,
 Also known as radio frequency identification , It's one . It's a communication technology , Specific target can be identified by radio signal and related data can be read and written ,
 There is no need to establish mechanical or optical contact between the recognition system and specific targets .

Work principle

 Just have a look  

RFID Middleware concept

 such as  linux  Of  cp  Instructions   cp xx.c xxx.c
xx.c  and  xxx.c  The stored directory may be different  
 That is, the attributes of each directory are different  
 This leads to the concept of a virtual file system  
 Virtual file system is to provide a common interface  
 Can be realized cp  Instructions 
 Middleware
