Uv Led Controller Man-machine Interactive Display Module Software Design

With the development of high-precision industrial technology, especially high-precision light soldering technology, UV-curing technology is became more and more broad in the market. High-power UV-LED technology is getting mature, which has an unparalleled advantage in the application of UV light source. Therefore, that high-power UV-LED light source is applied to the light-curing technology in order to achieve precise light curing welding technology, is now a study content in the area of light-curedAt present, most domestic and foreign light curing products designed by high-power UV-LED continued the previous high pressure mercury lamp function, which can not reflect the new features of the LED because there is no good intelligent control platform, as well as human-computer interaction module.The subject of the study UV-LED light source device, based on processor531ADI’s Blankfine Series, is equipped with DSP+FPGA structure, the intelligent UV-LED light source control test platform, as well as the appropriate human-computer interaction module.In this dissertation, the control platform of the system was be researched, mainly the hardware of display module drivers involved in human-computer interaction, as well as platforms of developing software and hardware, especially the memory management the system core processor Blankfin531.Based on Processor hardware, according to the hardware features of Blankfin531, detailed design, LCD drive is realized through the PPI interface; the two-dimensional data transfer software within system was designed by the DMA controller and the synchronous display of image data frame between the UV-LED intelligent control the processor; in order to realize full color display, color model is studied and RGB565color model structure was achieved according to the difference between the ADSP PPI interface bits wide and the data bits wide showed on the selected LCD display.On the basis of principles of Human-computer interaction system, firstly the most widely used embedded graphical systems are studied, classifying and comparing of their characteristics, which set up a valuable reference for the design man-machine interactive graphical of the dissertation.The menu structure study of human-computer interaction, a tree menu structure are chosen as the appropriate topic; and interactive programs is established according to the ideas menu interaction design; the return to menu and pop-up control in human-computer interaction are realized by software design.Finally in the stage of debugging of man-machine interactive display, according to the encountered problems and the characteristics of memory management controller of ADSP-Blanfkin531, and the transmission control features of DMA, data storage and transmission scheme were improved and finally solved the encountered problems.
