ucos2 can总线通讯

说明：  编程实现MCP2510 的CAN 总线通讯；两个UP-NetARM3000 通过CAN 总线相连接。ARM 监视串行口，将接收到的字符发送 给另一个开发板并通过串口显示（计算机与开发板是通过超级终端通讯的）。即按PC 键盘通 过超级终端发送数据，开发板将接收到的数据通过CAN 总线转发，再另一个PC 的超级终 端上显示数据
(Programming MCP2510 CAN bus communication; Two UP-NetARM3000 CAN bus link. ARM surveillance serial port, will receive the characters sent to another development board and adopted Serial Display (Computer and development board through the Super Terminal Communication). According to PC keyboards through the Super Terminal send data, the board will receive the data transmitted through the CAN bus, then another Super PC terminals display the data)
