can.h

本程序是针对Infineon公司的XC167CI处理器而编写的CAN网络程序。CAN（控制局域网）协议是一种广泛的应用于汽车电子的网络协议。本程序建立了三个CAN节点

///  -------------------------------------------------------------------------

// The following data type serves as a software message object. Each access to
// a hardware message object has to be made by forward a pointer to a software
// message object (TCAN_SWObj). The data type has the following fields:
//
// uwMsgCfg:
// this byte has the same structure as the message configuration register of a
// hardware message object. It contains the "Data Lenght Code" (DLC), the 
// "Extended Identifier" (XTD), the "Message Direction" (DIR), the "Node
// Select" and the "Remote Monitoring Mode".

//
// ulID: 
// this field is four bytes long and contains either the 11-bit identifier 
// or the 29-bit identifier
//
// ulMask: 
// this field is four bytes long and contains either the 11-bit mask 
// or the 29-bit mask
//
// ubData[8]:
// 8 bytes containing the data of a frame
//
// uwCounter:
// this field is two bytes long and contains the counter value
