Description
Summary:The paper introduces a LED configuration design with Chinese characters prompt, which is based on P89LPC932 and widely applied in the field display of various card readers. Hardware circuit principles, design ideas of configuration LED, display and protocol and key codes are expounded here, all of which help solve the problem of poor compatibility in the system caused by too many card readerspsila devices and userspsila requirement of fast development of software in embedded system. The design has been verified in simulated environment and field and it has many merits such as low cost, interchangeability,flexibility and so on. Whatpsilas more, it also can be applied in all field display in industrial controlled environment etc.
