基于ARM S3C2440的CANBUS总线的驱动程序，can 主IC为MCP2510，CAN 正负脚应该接120R 跨阻-Based on ARM S3C2440' s CANBUS bus driver, can the main IC for MCP2510, CAN feet should take positive and negative cross-resistance 120R

本驱动程序在s3c2440上实现了两路基于SPI的CAN总线控制器。两通道可以并行，并使用外部定义的两个信号量来通知接收任务收到CAN总线帧，并将其存入预先定义的队列中（帧定义在CAN总线控制器驱动程序的头文件中）。CAN总线控制器的中断引脚分别连接到ARM的EINT3和EINT8_23上-The driver s3c2440 achieved a two-way SPI-based CAN bus controller. Two channels can be parallel, and us
