Abstract： In order to solve the problems of low system integration and the week anti-jamming capability in the human-machine interface of knitting machine，a method of developing computerized knitting machine control system human-machine interface based on SOPC technology was proposed. By extending touch screen controller through the SPI interface，the human-machine interface was established by configuring a Nios II CPU soft-core，SDRAM controller，LCD controller，JTAG debug module in the EP4CE115 FPGA chip. The software designing used Verilog HDL language to write，including LCD driver，touch-screen interrupt etc.. Study results show that the kind of human-machine interface has merits of high system integration，strong anti-jamming capability，low power consumption，and is more flexible.
