Design of Colorimeter Control System Based on NIOS II

According to the demand of industry for measuring color,this paper designed a sort of colorimeter based on Nios Ⅱ and provided with wireless conmunication function.The control system of colorimeter adopted the FPGA embeded Nios Ⅱ.AD control module,matrix keyboard module,LCD display module and radio frequency transmission control module were around the NiosII to collect,process,store,display and wireless transfer the signal of color.The paper explained the configure of Nios Ⅱ and the program designing and simulation of A/D control module and radio frequency wireless transmission module in detail.
