| Abstract: | Aiming at the problem how to interconnect the CAN bus and PC safely,a CAN-USB interface adapter is designed based on ATmega128.At the same time,the hardware connection between MCU,CAN bus and USB interface,and the software implementation of CAN node and USB system are both provided.With the simple hardware structure and high reliability,the designed interface adapter can transmit data flexibly and high-efficiently in industrial control.This design also expands the supervision and management function of CAN bus in the industrial application,and expands the application of USB bus in the industrial control. |
