Developing of CAN-bus Nude Based on PIC18F458 |
| |
| Abstract: | The CAN-bus has strong rectify ability,long distance and high transmission speed,allowing for communications within noisy environments.The design of CAN-bus communication nude based on the PIC18F458,the hardware structure and software flow chart were introduced.The communication nude explored in this study maintains a simple structure,strong expansibility,high communication reliability,and strong anti-jamming ability,etc.,as a result,many devices can be easily developed on this nude.To be a universal long-distance communication,data-collection and control platform,it will have a wide application in the mine automation field. |
