| Abstract: | In order to control the high-step LED cube, the control system model of 32-step LED cube was established, the theory, technology and system framework of this driver were investigated as well. Graphical programming was done by master computer, and the compiled dynamic graphic was written into the RAM. Every processing module of the display driver was introduced and a feasible way for the static state displaying and dynamic debugging was presented. The results showed that this driver could display graphic and text in a faster and more stable way, fulfilling the needs of the display system. There were 32 768 LED units, when compared with MCU Solutions, the graphic and writing could be designed in an easier way. |
