If the position signal detected by other methods, will inevitably lead to the circuit design complexity, reliability decreased. The work theory of the controller, the hardware interface design between LS7266R1 and single CHip, and the flow chart of main program, are presented in this paper. The signal of the compression or tension power and displacement at working, which tested by power sensor and displacement sensor especially, is changed into electric voltage and electric pulse numerical signals. And these signals can be tested by A/D and counted by LS7266R1. Finally the test of the material properties can be controlled by itself, or controlled by the COM command of PC.
