我设计的CAN总线模块

bit can_Full=0;                     //CAN溢出标志

bit can_error=0;                  //CAN0错误标志
bit can_error_Appearance=0;       //CAN0错误状态
unsigned char can_error_ecc=0;    //CAN0错误类型
unsigned char can_error_rxerr=0;  //CAN0错误类型
unsigned char can_error_txerr=0;  //CAN0错误类型
bit can_error_es=0;                 //CAN0状态
bit can_exit_Appearance=0;        //CAN0脱离状态
bit can_ti=0;                     //CAN0总线发送完成

bit uart_data_w_Complete=0;//串口接收数据完成
unsigned char uart_data[50];
unsigned char uart_data_i=0;

unsigned char xdata can_data[700][10];
unsigned int can_w_data=0;  //写CAN接收缓冲区指针
unsigned int can_r_data=0;  //读CAN接收缓冲区指针

unsigned int id=2;


//i2c变量定义
