1 /******************************************************
2 **说明：此程序为Peli模式自测试程序，需要硬件四个LED，四个按键，
3 ** 当然按键可以不要，LED只用一个也行，只是不够直观。
4 ** 还有本程序是按一次按键，进入接收中断两次，也即是流水灯
5 ** 会流动两次，串口也会收到两次数据，原因未知，看来对CAN的体
6 ** 会还很有限。

9 **邮件：mozhenhua211@tom.com
10 **备注：不知道为什么用STC的单片机老是没反应，郁闷~由于本人毕设验收在即，
11 ** 所以暂时没继续寻找原因，待毕设完成再详细探讨。另外按键部分的处理
12 ** 以及SJA的驱动部分感觉十分累赘，编程风格目前正在形成中，望各位前辈
13 ** 指点一下。谢谢！
