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.
