摘要：Bio-sensor arrays for multi-channel recording have been developed recently and signal processing platforms for those signals have been studied *** it’s thereal situation which these technologies are generally developed and studied *** the interface design between recording array and signal processing platform is also an important issue to make bio-sensor signal processing *** this paper,we proposed interface which has unique protocols to control sensor array and operate *** are two types of protocols in the *** is between sensor array and MCU in platform and the other is between MCU and board for wireless ***,each protocol has two kinds of modes(single,frame)and it can be extended if needed.
