摘要
本文介绍了以Motorola公司生产的MC9S12DP256B为核心,采用液晶．数码LED以及步进电机仪表为显示器件,设计了一种新型数字式重卡组合仪表。系统还预留了CAN和LIN总线接口,便于功能扩展或者与汽车其他电子系统连接通信。系统的软件采用了以μC/OS-ⅡV2．00为内核的嵌入式实时操作系统,提高了系统软件的稳定性和实时性。
A new type digital assembled instrument based on MC9S12DP256B （produced by Motorota ） and LCD, numeral LED and stepper motor display are development, The bus interface of LIN and CAN is obligated in this instrument system, The aim of doing this is to make this system can easily expand system function and can connect and communicate with other automobile electrical control systems. Furthermore. the RTOS （Real Time Operating System） based on μC/OS-Ⅱ V2.00 is also applied in the design, And it improves the stability and the accuracy of the system.
