| Abstract: | Because of the problems of Modbus communication between touch panel and singlechip, Modbus communication protocol is analysed, gives the hardware circuit and control procedures. By monitoring the communication process through control circuit, the debugging method is intuitive and easy to identify the existing problems. The method can been taken as reference for the project. |
