ABSTRACT
In many medical instrumentation systems, there exists a long distance between manipulation platform and host unit. Wireless data transferring between the platform and the host could be a feasible way to set parameters. This paper introduces wireless transmitter and receiver circuit based on encoder chip PT2262 and decoder chip PT22720, and presents some typical applications in medical instrument development.
ABSTRACT
When PT2262coder adopted,a lot of PT2272decoders have to be used to realize large capacity decipher.In this paper,a decode system by PIC16C57is developed to perform large capacity decipher by many PT2272decoders.Some information of the system is also presented,such as its hardware control circuit,software control flowchart and application to the call service system in ward.
