| Abstract: | An electronic coded lock based on in system programmable (ISP) technology and complex programmable logic device(CPLD)is introduced in this paper. The operation principle and design of hardware and software of electronic coded lock are introduced in detail. It adopts the in system programmable large scale integrated chip of lattice corporation to integrate the periphery circuits and uses a CPLD to implement the function of tens of separated chips. Thus it reduces the system structure and enhances the reliability and cost performance of the system. The electronic coded lock is suitable for hotel, office building, warehouse and so on. |
