Because narrow band does not have frequency restriction on use,cause it to be easy to receive the disturbanc-e,as a result,its use is convenient,suits extremely in the short distance wireless applicat-ion.This designation uses UART to communicate with periphery equipment,SPI to configure CC1020's registers,and INT0 to finish data transmission.This article discusses a kind of data transmission module,using narrowband RF transceiver CC1020 and Single Chip Microcomputer Atmega88,for short distance trasmission.It analyses the principle and method of working ,also gives out design mentality,hardware circuit and programme. 摘要 I
