| Abstract: | In industrial real-time control system,the digital variables of embedded microcontroller can＇t be collected in real time.This is detrimental to system debugging,fault diagnosis and performance optimization.According to this problem,the paper discusses a solution based on isolated serial communication and a display with LabVIEW,and introduces the protocol of serial communication between real-time acquisition of microcontroller internal variable and PC as well as the graphical display of the data received by labVIEW.Finally the feasibility and effectiveness of the method is verified by experiment. |
