用AT89C52单片机实现RS-422到CAN总线的转换

Realizing Change from RS-422 to CAN Bus with AT89C52 Single-chip Computer

采用 AT89C5 2单片机 ,设计了 RS 4 2 2串行总线到 CAN现场总线的转换电路。该电路既可以将 RS 4 2 2数据格式转换为 CAN数据格式 ,又可以把 CAN数据格式转换为 RS 4 2

Use AT89C52 singlechip computer, and designed the RS422 serial bus change circuit to the bus at CAN field This circuit already can change RS422′s data format to CAN′s data format, and also can change CAN′s data format to RS422′s data format
