基于ARM的加密锁设计

Design of Encryption Lock Based on ARM

介绍一种基于ARM的密码锁,它对系统的硬件设计和软件设计进行详细的描述。硬件方面,系统采用LPC2114为微控制器,CSI24WC02为E2PROM。LPC2114通过I2C总线与CSI24WC02通信以实现系统功能。软件方面,系统主要包括加密和解密两部分。

This paper presents a kind of encryption lock based on ARM technology,which describes hardware design and software design in detail.In the hardware,the system chooses LPC2114 as microcontroller,and CSI24WCO2 as E2PROM.LPC2114 communicates with CSI24WCO2 by I^2C bus for system function.In the hardware,the system is made of two parts,which are encryption and decryption.
