ARM与独立CAN控制器的时序适配

Timing Adaptor Achieved between ARM and Stand-alone CAN controller

随着嵌入式系统电子技术的发展,大量MCS-51产品由于时序、电压等的差异难以直接与ARM处理器直接相连,通过介绍ARM与独立CAN控制器SJA1000的适配实现,系统地分析了在ARM应用系统中基于MCS-51时序外设的扩展方法及各自的特点;结果表明对ARM应用系统外设的扩展具有典型性和现实意义。

With embedded system technology＇ s developing, a large number of MCS--51 products can＇ t directly link with ARM because of their discrepancy such as Timing, Voltage. The methods to achieve Adaptor between ARM and stand- alone CAN controller SJA1000 is introdued; expansion--methods of peripheral based on MCS--51 Timing in ARM application system are systematically elabora- ted, and analyzing their characteristics. The application result shows that the design has typicality and actual signification on the expansion of ARM application system＇s peripheral equipment.
