Abstract: FPGA and ARM were used as the core controller, six SSI interfaces and one RS232 serial port hardware circuit were designed. By using Verilog HDL language to program the sequential circuit of SSI interface FPGA, the functions of sequential control and signal acquisition of six channel SSI interface absolute value encoder were realized. At the same time, the FreeModbus protocol stack was transplanted into the hardware platform of this paper to realize the data interaction with Kinco touch screen and display the six channel encoded data in real time in the human-computer interface. The engineering practice shows that the design scheme is stable and reliable.
