摘要
本文介绍了基于LPC2148和MCP2510的USB-CAN接口卡。LPC2148是基于ARM7TDMI-S核的微控制器,处理器速度高,内置USB2.0全速控制器和SPI接口。MCP2510是独立的CAN控制器,支持V2.0A/B技术规范,通过SPI接口与微控制器进行通讯。接口卡能够实现计算机与CAN总线网络之间的高速数据交换。主要介绍接口卡的硬件电路设计及其详细编程。
This paper introduces the USB-CAN card based on LPC2148 and MCP2510. LPC2148 is an ARM7TDMI-S core microcontroller, that has high CPU-speed, with USB2.0 Full Speed Device Controller and SPI bus. MCP2510 is a full CAN protocol controller implementing CAN specification V2.0A/B. It communicates with microcontroller via SPI bus. The card can implemente communication between computer and CAN net with high speed. This article introduces the hardtware and software design in detail.
